Abstract: The METS schema is a standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library. Topics to be discussed at this year’s annual board meeting include the development of METS Lite, METS RDF, relationship to other standards, and maintenance of the existing 1.0 schema.
The meeting is open to the public. Potential attendees include METS users and potential users, adopters of closely allied schemas, such as PREMIS and ALTO, as well as anyone with a general interest in formats that promote standards based description for the exchange of complex digital objects.

歴史資料デジタル記録として何を記述すべきか―日本とアジアと世界― (with translation)
Organizer: Makoto Goto (国立歴史民俗博物館 National Museum of Japanese History)
Presenter: John Ertl, Yoshiko Shimadzu, Shigeki Moro
Abstract: There are a variety of methodologies for preserving historical resources in Japan. Ultimately, the main point “What and how can we predict the future?” matters not only the original resources but also digital data. This session addresses underlying problems, “What do we record?” and “What are the outstanding issues for information record from historical resources” from the scope of archaeology, scientific studies on cultural properties, and digital.

Discussion (all participants):
Speaker: Ingrid Dillo (Data Archiving and Networked Services, Netherlands)
Title: FAIR Data in Trustworthy Data Repositories
Chair: Klaus Rechert
Abstract: National and international funders are increasingly likely to mandate open data and data management policies that call for the long-term storage and accessibility of data. Open data and data sharing can only become a success if we put the concept of trust central stage. The certification of digital repositories is an important means to provide this trust to the different stakeholders involved. In this keynote 1 will talk about data sharing, repository certification and the concept of FAIR data.

Ingrid notes that iPres is happening alongside meeting of the WDS - World Data System - Asia Pacific conference. Research data invites conversation about data sharing and trust, and certification. This allows us to link the discussions on digital preservation to current topics like FAIR and Open Data.
Links between Japan and Netherlands long established for trade but also learning. The shared history between the Dutch and the Japanese is based on trust, which should also the basis for scientific & data exchange.
Research Data Management (RDM) in the era of Open Science. Data sharing is important for transparency; replication of research; facilitates re-use of data, and in turn efficiency, return on investment etc. 19th c. Whaling logs used by climate scientists today are an example of the reuse of records outside the original domain for which they were created.
The Concept of Trust
What do researchers thing of open data? Most are supportive in a survey. However most researchers do not make their data available in a way in can be used by others. Intellectual property, confidentiality, misinterpreted, ethical concerns, attribution etc. Trust issues. If you create a system…“will [my data] be lost garbled stolen or misused?”
Data sharing is key to reducing data fraud - prominent cases in the Netherlands (worldwide).
As per survey, majority of researchers seem to approve data sharing … however, in reality the majority of them don’t. They keep data for future use on their computer at work or on portable storage carriers and are worried with intellectual property concerns, misuse concerns, etc. Data that is not shared typically sits on private disks or portable storage, immediately raises a derived preservation issue.
What can be data sharing incentives?
Sharing needs to become norm and there have to be professional rewards for data sharing. External drivers in this context are funder policies and publisher requirements.
Incentives for researchers – culture. Mostly affected by their peers/research circle, if sharing is the norm. Getting academic credits – reward for investment.
Pillars of trust - integrity, transparency, competence, predictability, guarantees, positive intentions. External acknowledgements.
Global certification landscape
There are two standards for repository certification ISO16363, DIN 31644; and there is the Data seal of approval.
DSA and WDS are lightweight, self-assessment, community review. Disciplinary & Geographical spread. Now replaced two with one set of requirements using best of both, two became one under the auspice of the Research Data Alliance => Core Trust Seal
DSA and WDS recently joined forces to form partnership for assessment - goal for partnership was to simplify assessment options and to stimulate more certifications.
CoreTrustSeal is the result - now contains common catalogue of requirements between DSA & WDS. Using best of both, two became one under the auspice of the Research Data Alliance.
Core Trust Seal:
Core Trust Seal is based on self-assessment. Peer reviewed.
16 requirements. Self-assessment (publicly available) . 3 year seal period.
When you receive a seal, info you’ve provided becomes public. This encourages ‘trustworthiness’ and common knowledge, shared learnings.
New requirements – need to have many people involved, insight into organisational structure, staff, funding.
Core level: World data system or Data Seal of Approval.
Lightweight standards. Self-eval, reviewed by committee. Originate in Europe.
One new certification body to replace WDS and DSA. New body is called Core Trust Seal (launched 11 Sep). (Perhaps unprecedented since the norm is for standards to replicate rather than be reduced coherently. A significant accomplishment in community cohesion[a])
Research Data Alliance (RDA). 23 things: Libraries for Research Data. Great resource.
Deeper dive into the new CoreTrustSeal standard. Three broad components of the standard - organizational infrastructure, digital object management and technology.
Why do institutions undergo certification?
· Why do repositories invest in certification efforts?
Builds stakeholder confidence/trust in the repository, raises awareness, improve communication within the repository, improve repository processes, and, to differentiate yourself from other repositories.
Importance of certification – seal holders & very god reward for investment. Many think ‘Core level’ is enough.
NCDD report on perceived benefits of data seal of approval shows that there was a strong ratio between effort and rewards for the seal of approval. Almost no one aimed for certification at the higher level so the core trust requirements seemed to be sufficient for most participants. Report availble here: http://www.ncdd.nl/wp-content/uploads/2016/10/201611_DE_Houdbaar_Report_DSA-survey_2016.pdf
Certification like CoreTrustSeal says something about the quality of the repository, FAIR data principles say something about the datasets contained within.
Matrix was developed with 5 criterias / stars for each category (Findable, Accessible, Interoperable). Stars in the criteria shall automatically lead to R = Re-use. This is the first step towards an assessment tool.
FAIR and Open
FAIR data - Findable, Accessible, Interoperable, Re-usable
Guarantees of technical quality. Need licences, continuity plan, integrity checks, long term storage, sufficient metadata, IDs are mandatory.
A lot depends on depositor, eg metadata attached
FAIR Badge Scheme / Data Assessment Tool:
Core certification does not differ from concept of FAIR – tried to operationalize concept of FAIR.
Tried to come up with metrics for FAIR. Prototype being tested. Hard to define metrics for R, so we decided to add up FAI to get the R.
Have Survey Monkey questionnaire, user tested.
Some people say that FAIR data has nothing to do with OPEN data - however, Dillo says that there is a relationship because accessibility has a lot to do with openness. However, some data just can’t be made openly available so they won’t be able to achieve 100% It’s unfair! But that’s the way it is. Also Open is not necessarily the key to fairness. It’s a combination of Open and Fair that we should be aiming for.
Levels of openness – Datatags
New European laws around personal data (similar in other geo-locations). Sweeney & Crosas introduced the notion of datatags. Working on system of levels based on GDPR – GDPR DataTags. Researchers complete questionnaire (it’s currently in draft form).
Comment from William McBride: regarding GDPR (data protection regulations). If risk averse organisations hear a message that they should be reducing the amount of data they have, a strange consequence of this is that may be that we have less or no data to preserve. Lessons to take home - preservation is not an unrealistic thing to attain [great message Ingrid is giving]; and, data protection regulations – take account of that work. Strengthen relationship between data protection and digital preservation.
14:40-16:40 @ Main Hall
Abstract: Countries in the Asia-Pacific region are very diverse in terms of culture, language and economic environments. Long-term management, keeping and use of digital resources is a common and pressing concern for many of these countries which are producing more and more digital resources. However, reports on digital preservation activities are lacking, especially from the countries in East and South-East Asia. This session is aimed to share up-to-date information about developments of digital archives and digital preservation in East and South-East Asia and to discuss issues on digital preservation in this region with the audience from other parts of the world.
This session will first present five talks by invited speakers from Japan, Taiwan, Philippines, Thailand and Singapore about digital preservation at the speakers’ institutions and/or countries. Then, we solicit voluntary reports from other Asian countries followed by general discussions with the audience.
Moderator: Natalie Pang (Nanyang Technological University)
Invited Speakers: Shuji Kamitsuna (National Diet Library, Japan), Sophy Shu-Jiun CHEN (Academia Sinica, Taiwan), Lee Kee Siang (National Library Board, Singapore), Wararak Pattanakiatpong (Chiang Mai University, Thailand), Chito Angeles (University of the Philippines Diliman, Philippines)
Digitally endangered species - #bitlist
Philippines - digital archives from newspapers. Hard to track down, not a clear responsibility. Delighted to find materials archived in other countries
Japan - intangible cultural heritage preserved in local villages. Elderly populations.
Singapore - Social media, snapchat in particular for young people. Snapchat is a subculture so even when captured the context is lost.
Singapore New technology allows publishing to be fast but not good at capturing content for archives. These are our new real challenges
Japan - context for the photographs; games are lost too quickly, but Japan has a lot of expertise on this. Nintendo.
How to capture emotional response and experience of digital artefacts. Anyone doing this? Generational gap.
Disconnect between generation. How do we address this issue?
Cambridge, UK: depends on what kind of materials formative years. Gen X = old computer games, emotional responses. Material changes over time. I might not have the same response to an app, but my peers would. More pertinent, are the younger gen taught to look under the hood? They might know how to use tech superficially. They might not know the nuts and bolts.
Kee Siang (SG): Citizen archivist programme. Encourage citizens to contribute. Old gen and their kids input metadata related to the photo or manuscript. Aging population -> oral history, capture their memories. Training institutions to conduct oral history. Audio form. Audio to text conversion.
Taiwan: a lot of old photos. Historical maps. Digitise only historical maps with GIS. Combine photo and maps. Produce modern publication, walking into old taipei, old tainan. Young ppl can use the app, enjoy the digitised materials.
Dr Natalie Pang: Bukit Brown cemetery. Document tombs and Graves. Old cemetery, belongs to generation before Singapore was formed. But the idea was to layer maps (GIS) with tomb inscriptions and story of the descendents. Project didn't come to fruition but this is one idea to bridge the gap.
KAMITSUNA, Sjuki - National Diet Library, JAPAN
How can we use we archives? A brief overview of WARP and how it is used
WARP is the web archive of the National Diet Library
Harvesting at National Library - current size: 1 PB, 5 bio files, 130,000 captures.
85% of that is open access / freely available websites to the public via the internet.
Use Case for the WARP archive:
Use Case 1: Linking from Live websites
WARP can be used to push data into the web harvesting process of the National Diet Library. Many public agencies use this as a form of data back-up, where websites are pushed into WARP prior to update.
Use Case 2: Analysis and visualization
WARP data is exploited to create aggregate and visualize information on Japanese websites, e.g. for relative size of data accumulated from each of the 10.000 websites archived in WARP.
Use Case 3: Curation
Creating a specific collection - e.g. around the earthquake
Use Case 4: Uncovering PDF Documents
WARP uncovers PDF files of book and periodical articles that are contained in websites - 1.5 mio PDF records were pushed out to the catalogue that way through WARP
Current indexes comprise 2.5 billion files in 17 TB of data - results contain much duplicate material archived at different times and other forms of “noise”. What is needed is a robust and accurate search engine specialized for web archive which must implement temporal elements.
Website of iPRES2017 is already archived in WARP
A Review of Current State of Digital Preservation in the Academia Sinica Center for Digital Cultures / Taiwan
Large scale Digital Library Initiatives in Taiwan data back to 1998. 100+ institutions (GLAM, Academia) have contributed to digital archive with over 5 mio digitized objects and over 750 websites & databases now in the archive.
Digitization Guideline Series has been put forth by Academia Sinica Center.
Linked Open Data principles have now been aplied to some websites (e.g. “Fishing in the Data Ocean Project” - https://summit2017.lodlam.net/2017/04/12/fishing-in-the-data-ocean/
Curating Tool: “DIGIMUSE System”. Includes Temporal and Spatial module for easy discovery along map / timelines.
Redundant storage - > 100 km apart, on file basis weekly.
Currently running pilot project on emulation.
Refreshment and Migration: on demand transfer of data between two types of same storage medium so there are no bitrate changes or alternation of data, esp. For digital objects of audiovisual, video, etc.
Overview of Digital Preservation National Library Board Singapore - Lee Kee Siang
Singapore is a very “wired” community - the #1 smart phone users in the world, where the average person carries 3.3 devices. Very high rate of internet access.
NLB oversees the Public Libraries (26), National Library (1.9 million visitors yearly), National archives (>40,000 visitors yearly).
“Digital Preservation” is a dedicated focus area within the national digital strategy. The goal is for every citizen to be able to access and personalize the data.
“Everything in the NLB Collection that is precious will be ingested and preserved beyond this generation”. This is achieved using:
NLB’s digital preservation journey started in 2005, moving things to different storage.
2011 - Rosetta was implemented as a digital preservation System.
2012 - the National Library and the National Archives of Singapore merged.
2018 - the Digital Act will be enacted which will clearly differentiate between mandatory and voluntary deposits. It will also allow web harvesting.
The Singapore webarchive started in 2006. Collection principle: websites about Singapore, from Singapore.
Web archiving Curation system includes pre-harvesting, harvesting and post-harvesting functions.
Ongoing efforts include streamlining preservation policies and strategies. Challenges include balancing between overwhelming content and limited resources. The lack of organizational responsibility, resources and infrastructure supporting active preservation activities.
Q/A: What about dynamic websites?
Audience recommendation: Webrecorder from RHIZOME - see webrecorder.io
Audience feedback: webrecorder is a great tool, but will fall short for use cases like NLB Singapore because it doesn’t scale as well. We need to fundamentally address that problem as a community where we are still working with tools and processes that are decards year all.
CMU’s LIbrary’s Digital Archives and Digital Preservation
CHiang Mai University Library, Thailand
CMD Digital Archives holdings:
Etds, e-heritage manuscripts from library’s holdings, microfilm digitization results, e-rare books, local newspaper and thai newspapers (digitized directly from 2015-present, digitized from microfilms for 1953-2014), e-commerce archive.
Academic records = approx. 27k, stored in DSpace repository with Dublin Core metadata.
Enruring Long-term Access to and Preserving the Cultural Heritage of the Philippines and the Institutional Memory of its National Univeristy
Digital Preservation Initiative at the University of the Philippines (P) and Collaborating Institutions
National University in the Philippines is only university in the country, founded in 1908 - divided into 8 campuses
22k students, 1.5k faculty at main campus
Material is collected based on “Decree on Legal and Cultural Deposit”, signed in 1975
“Within one month from the data of any printed book … is first delivered out to the press, the publisher of such book shall furnish, free of charge and in the same finish as the best copies of the same are produced, two copies thereof to the National Library, and a copy each to the UP Main Library, the UP Library at Cebu City, the MSU Library, …”
Additionally: Executive Order No. 13 which establishes University Archives to collect and maintain archival materials.
Milestones of digitization and preservation activities (2005 - present):
2005 - outsourced digitization project (microfilm)
2008 - first in-house digitization with hw purchased
2016 - digitization services expanded
Early 2017 - digitization and digital preservation services were expanded with the acquisition of new scanners and storage devices; also Digital Archives @UPD with ETD submission launched.
- The eLibrary Project
- UP’s institutional Repository Project - eprints to DSpace, then in-house development
- Digital Archives @ UDP containing thesis, records, personal papers, UP Presidents’ papers
- Digitization hardware: various scanners, AV converter
- Formats: JPEG for image, MP3 for audio, MP4, FLV for video
- Infrastructure, eg SAN
Challenges include IPR, technical obsolescence, data migration, interoperability, sustainability
Question to the panel:
William Kilbride, the Digital Preservation Coalition
“What is the most digital endangered material which the participants in the panel worry about?”
Chair: Unmil Karadkar
Katherine Thornton, Euan Cochrane, Thomas Ledoux, Bertrand Caron and Carl Wilson. Modeling the Domain of Digital Preservation in Wikidata
Chunqiu Li and Shigeo Sugimoto. Metadata-Driven Approach for Keeping Interpretability of Digital Objects through Formal Provenance Description
Metadata longevity should be ensured as well for future use. Provenance is crucial component of PDI defined in OAIS. Provenance of metadata describes change history, responsible agents, activities occurred on metadata objects. The changes of metadata definitions should be traced to prevent inconsistencies in the future use of metadata. Proposal of a model to describe provenance of metadata application profiles based on W3C PROV and Singapore Framework for Dublin Core Application Profile.
Provenance description should be machine-readable, traceable, and interoperable in the Web environment.
Digital Art ity - Building a Data Model for Digital Art Corpora
Celine Thomas, Bertrand Caron
3 year French research project, started in 2015, combining skills of digital arts & digital preservation
Includes interactive art exhibitions, with almost autonomous pieces; e.g. artworks based on algorithms displaying light cubes based on human interaction / movement; robot dogs fighting against each other based on random algorithms
Often involved custom made software / hardware
In France digital art is the most used use case for preservation of interactive objects
Creating entity map of (...some info missing…). Event / experienced artwork
How to get information on art works development / intention /experiences?
E.g. taping artist while interacting with their art work and explaining the work
If done with the captured environment (e.g. at BnF), artist con confirm whether preserved art work is working as expected or not (interview with artist as QA)
Project transformed entity map into ontology
How to capture information on art work in BnF’s catalog?
Intermarc format used: pros - very granular structure & evolving taxonomis; cons - fixed fields and not designed for the specificities of digital art description.
Challenging, but possible.
In the digital repository digital art objects are structured in METS files. Stored in different systems (on the agenda is migration of art works into the SPAR system).
SPAR system has little experience with preserving software - art work media img will be a first for img within SPAR.
Packages described in 2 METS files will include:
METS file 1
Two METS files are linked together
Q: impressive METS diagram - but what are your plans for how to get it all back out if you want to move it to a different installation?
A: we are just at the beginning of the reflection on emulation. The work we need to do is gather experience from the IT department, from the AV department that has a lot of experience with manual emulation. When currently some kind of multimedia document is requested by the reader in the reading room, the package was disseminated from the audiovisual-system and there was a totally manual operation by the engineer preparing the standard computer setup / virtual machine / emulator required. Due to this there is currently a large percentage of work that cannot be displayed to the public. Not sure what degree of automation we can reach.
Q: when you add the environments to your schema, do you use some kind of schema or are you looking at developing your own?
A: it’s based on PREMIS3 specification to add environments and the link / relationships between object & environment.
Q: with the installation plan you add to the plan - what do you add to that? How do you keep track of the installation? Capture all lines for example? Is there an automated process to confirm the installation instructions you captured?
A: There are standard processes for each package that we have, which will be included in the documentation. These are not really machine readable yet.
Q: Description - descriptive models we are using are just not concise enough (yet). If you would start from point 0, how would you build an access system that is flexible enough to allow for all access requirements to our digital objects for our users? E.g. in case of uncertainty about data, about provenance, about software, about hardware. Descriptive properties need to be flexible enough.
A: Big question, will have to think about that.
Problem: providing a secure remote access to restricted born-digital content
Solution: secure, trustworthy and portable emulation architecture for digital preservation
- protects the confidentiality and integrity the sensitive content against malicious IS
Trustworthy emulator-GameBoy prototype
Connection to emulator between user & server might be done using secure encrypted load cache
Goal: to seal emulator being used from end-user platform to run in a secure way so it can’t be compromised by malicious software etc.
Requirement for this: service providers trust secure hardware (in this case Intel SGX)
What the solution doesn’t protect against: side-channel attacks, displayed output could be captured via screenshots or audio recordings
How can you establish trust in a remote system?
How do you verifiably execute a program on a remote host?
In progress: checking into trustworthy non-emulation platforms
E.g for for PDF →
Xpdf and XpdfReader use following libraries: Qt (for UI), FreeType (for font rendering), libpng (for handling png images), Little CMS
In progress: More general purpose application, i.e. trusted full system emulator “Basilisk MacOS emulator”. Goal is to run encrypted content as VHD disk on Basilisk emulator
Q: Is Intel SGX needed on the client side? If so, it will really limit the usage on the user side.
A: Completly right, currently it is limited because it’s expected on the user side. But we think that this will be different in the future.
Software Heritage - Why and How to Preserve Software Code
Software Heritage - Roberto Di Cosmo, Stefano Zacchiroli
“The source code for a work means the preferred form of the work for making modifications to it” - GPL license
In the future, software code will be the only place to find all information about the software and it’s intention / structure.
In a sense, open software is common material / information. Are we as a cultural heritage community taking good care of this?
Where software is published on the internet is flux - many “fashion victims” exist (like Sourceforge). Projects tend to migrate from one place to another over time.
Like all digital information,FOSS is fragile - due to inconsiderate / malicious code loss (e.g. Code Spaces) or business-driven code loss (e.g., Gitorious, Google Code) or obsolete code / physical media decay
Data structure of archive - a giant Merkle DAG with no loops
Archive is live - currently containing around 4 billion files (unique), 900 mio commits, 65 mio projects
GitHub, Debian, GNU, WIP: Gitorious, Google Code, Bitbucket
150 TB blobs, 5 TB database (as a graph 7 billion nodes + 60 billion edges
We believe this is the richest source code archive already
How to use the archive:
It is now urgent to preserve software source code itself
Software heritage is taking a very systematic approach, has synergies with cultural, research and industry needs
SW heritage is a shared infrastructure that can benefit us all … we should collaborate and pool resources to make it so.
Q: Are you planning to include virus code as well?
A: I’m sure we already have viruses in there - we’re archiving github after all. We’re complying with local regulations.
Q: Are you collaborating with blackduck?
A: we are not, they are aware of what we’re doing. They are more for a commercial use case in connection with license information. We are after an open provenance db approach. We would like to build shared data and infrastructure that these companies can build on.
Q: As source code is mostly text - if you are crawling repositories, are you just harvesting text or also the binary? And have you encountered any text encoding issues, e.g. by grabbing tar balls from old projects or for non-UTF-8 stuff.
A: No, we’re not discriminative against files, if you have binaries we take them. We haven’t find any encoding issues in archival, because what we are archiving is just bytes - of course in displaying them, there will be files that we cannot display on your browser and in that case we will just let you download that!
Q: What is your preservation part of what you are doing?
A: Right now 3 copies - 2 on premise, 1 with cloud provider. What we stored once is stored forever, if we are forced to download something it will only be taken down for download not for archive. Persistent internal identifiers. Healing copy mechanism is in place.
Adding Emulation to existing Digital Preservation Infrastructure
Emulation as a Service
EaaS - number of “base environments” (Win 95, 98, etc) were created and made available via the service
The METS record is created describing media installation and usage order (e.g. for multi-part discs)
Metadata gets embedded into Preservica which makes it available via its REST API
The EMIL Characterization tool which comes as part of the EaaS package is run for gathering the technical environment requirements
What are the current Barriers to widespread use?
IT’s currently not embedded in existing digital preservation off-the-shelf systems, because …
…. Technical: shifting lots of data around, big disks & big emulators. Ingest throughput. Validating less common platforms. Server based systems. Continuous updates. Future server based systems?
… Management: organizational limitations in personnel
… commercial barriers: protection by copyright law on so many levels (not just microsoft, but even the obscurest little package in Windows)
Phantoms of the Digital Opera: The need for long term preservation of born-digital actors and multimedia objects using methods that permit ongoing new creations
Dena Strong / U of Illinois
Problem: researchers on decade-long or multi-decade projects need to be able to preserve objects while still trying to work on them
→ is this a digital preservation problem? If not, who is going to take care of it?
Creators need to whole “opera house” - actors, sets, costumes, lights, sound … and each component needs to remain editable and “active”
SHINKAI Makoto: Hoshi no Koe (Voices of a Distant Star) - created in 2002, if re-released today, this would have to be recreated from scratch
Nina PALEY, Sita Sings the Blues / Book of Exodus - chose fossizilation and a digital divide within her own body of work; split her systems between first interview (2014) and second (2017)
David Fleming, professional translation for anniversary editions, DVD to Blu-ray series conversion. SubTitling requires sub-section exact work. SW/HW used is SubStation Alpha last updated in 2001, Excel plug-in compatibility needs Office 2003, Video converted from VHS no longer accessible in Win 9.1, Frame rate mismatches
What’s the path forward?
Four primary tactics and a dream:
Emulation - promising, but currently incomplete and difficult for users
Migration - rarely 1:1, significance depends on project.
Re-creation - redoing old work takes time away from new work
Fossilization: many creators only option, but fragile
My dream: easy-to-create, easy-to-use portable cloud-based emulation …. But how do we get there? (codecs, drivers, licenses, etc.). And what about software that now only runs in the cloud which you can’t own? (like Photoshop 2017)
Dream world includes easy to use, hardware independent bt hardware-clone-compatible containerized emulation; grandfathered licensing when old versions were owned but new ones are “rented”
The dream: “See this system I’m typing on at the moment? Make a containerized cloud copy of it for me. Oh, and do it in just a couple clicks. Then I can get on with my actual creative work / research work”
Q (from presenter): Is this preservation?
A (from audience): yes. At least personal preservation. Much content being preserved must still be re-used.
A (from audience): regarding dream world - we’re almost there
Sarah MASON and Edith HALVARSSON. Designing and Implementing a Digital Preservation Training Needs Assessment: Findings from the Bodleian Librariesʼ Institutional Repository (S)
Sarah background on DPOC, the training pilot:
Training pilot background:
Two rounds of semi-structured interviews
Round 1 Winter 2016, Round 2, Spring 2017-09-27
What do we mean by digital preservation skills?
Sarah & Edith did an extensive literature review
Selected DigCurV framework from lit review: it has three lenses, Executive, Manager, Practitioner with progression pathways. Also provides 110 different skills and attributes – used these to customise final list.
Next step: map DigCurV to other frameworks.
Discovered during literature review: core DP skills – “technical skills”, metadata standards, communication skills, domain specific and digital preservation knowledge, project management and preservation planning skills, Understanding the “designated community’s access and research needs, legal frameworks
Round 1 Interviews: Findings & Trends
Edith on the first round of interviews:
Interview various staff from the Oxford University Research Archive (ORA) (Repository for scholarly outputs)
Practitioner questions used, and manager questions used for different staff levels
Findings: all staff were strong in traditional library skills (metadata editing, communication, legal frameworks, self-directed learning
Gaps: understanding how digital preservation fits into the ORA service, but had a good grasp of types of digital preservation risks.
On digital preservation specific knowledge: what this actually is is up for debate! The approach we took was random selection of terms – asked staff do you recognise these terms? Do you know what they mean? Only one member of staff recognised all of the terms, this person was the only one who had completed a post-graduate qualification in digital curation.
Sarah on round two of interviews:
Interviewed developers: 6 software developers from Bodleian repository. They had a good understanding of metadata standards, data models
None were familiar with digital preservation language - but knew it in different terms. Highlighted need for common language.
Key finding: communication has become a key skill across all roles, even more than technical skills.
Future work: developing an in-house training program based on the findings. Will give staff common language, and is a starting point for future education offerings.
Sarah: I’ve run some classes on personal digital archiving - has been a good starting point for awareness raising among staff.
Questions for the audience: what do you find is the most important digital preservation skill that you have? What digital preservation skill is lacking in your organisation?
Audience Q&A: Digital literacy is still a big problem, digital preservation is so far away from the basic upskilling for librarians etc. in some contexts.
DAM System put in place
Facilitates asset creation & cataloging of image & video & text files
Manages high-resolution master files & original documents
Tracks preservation actions
Has version control
Was hard to convince people that digital preservation starts at creation
Let’s look at PDF/A-a
Constrained version of PDF/A
We have to create a second structure tree parallel to the tree for drawing the pages in order to create structure
→ add 11 new objects (and altered 3) to our PDF document just to add the logical structure
Clearly shows that accessibility was specified as an afterthought for PDF
Creation vs Conversion
PDF/A A-level conformance depend on (structural) information available in creation context → if not present, the information CANNOT be generated
PDF2 - tries to remove ambiguities in spec, tagging support aligned with PDF/UA for better accessibility → will most likely result in PDF/A-4
Joost van der Nat and Marcel RAS. A Dutch approach in constructing a network of nationwide facilities for digital preservation together
Linked open data is likely a mechanism that can connect silos.
Goal of the project to increase effectiveness. Defining “completely effective” in a scenario where smaller institutions can keep digital materials for as long as required.
What is infrastructure when you’re talking about digital preservation? ICT component, OAIS box needs to be embedded in archive management – if you don’t start at the beginning, applying the correct metadata, you won’t find it easy to digitally preserve.
Building blocks for digital preservation
Angela DAPPERT and Adam FARQUHAR. Permanence of the Scholarly Record: Persistent Identification and Digital Preservation ‒ A Roadmap
Reuse over space and intent has the same problem shape as reuse over time: message is we need to use the lessons that we have learned in digital preservation – we’ve learned a lot in 15 years, and PID systems should take these lessons in board as there are gaps in current practice.
Pid services came to be with a clear purpose, when they reached a goal they expanded their practice/scope. – in digital preservation we’ve done the opposite – lots of thinking – what’s the concepts behind what we do – and because PID systems grow organically, the data models are not as extensible and interoperable as they should be.
We use premis as a main data model – agent, rights, events. We never talk about an object without clarifying what it is we’re talking about.
PIDs – don’t do this. Don’t do machine harvesting or machine interpretation. Recommendation: PId services need to rethink the underlying data models especially if we want to harvest the research output.
Technical metadata – tech metadata needs to be created as early as possible in the information network eg file types, creating software, computing platform
PIDs concerned with partial and dynamic datasets – researchers work with cleaned subsets of base data – if we use premis it can identify clearly the derived dataset – so that it can be computed on demand from the original data set.
Provenance information in the scholarly record: crossref and datacite events are no based on a common data model like we have in digital preservation
Lesson: need to translate digital preservation data modelling into deliberate design for PID services – locally, in apis, in web environment
The panel consists of Anthea Seles (US), Andrea Byrne (UK), Jones Lukose (Netherlands), Bertrand Caron (France), Dr. Xiaolin Zhang (China)
Question 1: What does digital preservation looks like if you do not have the skills available in your organisation? How can you do something, and what is good enough?
Andrea S.: Need to be clever around how we use our skills and decide what we will/will not support. These are hard questions which we need to ask ourselves.
In terms of my experience in Africa, and what my African colleagues are facing, there is no skills training. There is no infrastructure to train staff.
Andrea B: DP is a learning curve - you never know enough and there is always something new. The important thing is that we need to inspire staff to continue learning and being curious. Project management training with staff is the kind of thing we may want to focus on.
Jones: Grew up in Kenya (left 12 years ago), and there has been a large digital revolution at home in the last five years. Businesses etc. are moving completely away from paper. This is the right time to go back to Kenya to try and change the mindset of this new generation.
Bertrand: For us at the BnF, we need to become better at sharing. It would be good to be able to give staff something similar to a “competency map” to display what people's’ skills are. We also need basic training with all staff, go give them a minimum level of DP skills.
Xiaolin: Sometimes we are approaching this lack of skills problem in the wrong way. I am running a national DP project. Staff want simple, quick, hassle free training - they do not want to “become us” [as DP professionals]. Two hours maximum training is probably fine. Then when you put processes in place, you will end up forcing that skills up as well.
Comments from the audience:
Why was IO-OO model necessary in Denmark? Denmark wanted one central bit preservation system used by several organizations spread across Denmark. The joint project started in 2009. Goals was full independence within the system for the different organizations, multiple copies, etc.
OAIS was chosen as the common language to model the system - however, it became confusing when processes relating to the OAIS functional entities take place either within the shared bit storage system or within the repository system in use at the respective organization (e.g, where migration takes place).
Time has come now to audit the Bit Repository (IO level).
Examples of the audit.
IO should be independent personal - e.g. if someone has too many administration rights, this needs to be fixed.
Independent Operating systems - Windows and Linux servers
Independent Organisation - currently looking at the implication of libraries merging
Other examples of checks:
Preservation Planning: including media
Audit of Bit Repository - IIO level
Bit integrity challenge: Is the trigger for changing tapes set right?
Specific confidentiality challenge - e.g. external service provider has direct access to system, this is a no-go.
Other cases who use the OO-IO model / have been informed by DDP project: MetaArchive, BitRepository.org, DuraSpace, Chronopolis, etc.
IO-OO can be used for other processes as well, e.g. ingest
“Minimal effort ingest” (see iPRES2015 ) used in first step to be able to ingest quickly instead of having to wait for long curation time, etc.
This can be modelled as OO-IO as well - this can be modelled via IO-OO as well. When SIP is ingested via minimal effort ingest, is becomes an AIP in the Bit Repository but is still being worked on outside (e.g., to finish curation processes, gather metadata).
Helen Hockx-Yu - University of Notre Dame
Superb Stewardship of Digital Assets
Hockx-Yu job: based on the expectation that stewardship requires close collab between IT and library
Gap analysis has been done looking at the current status of data stewardship at the university
Digital assets are records, data, resources typically owned by the univerity & thought of as having value - no discrimination between born-digital & digitized
3 categories: uni records, research data, resource for teaching/learning/research
Gap analysis put forth that UND is in good position to address gaps but there’s currently a siloed approach with a lack of coordinated, cohesive view of digital assets and uneven use of tech across orga. There’s a strong focus on “now” and some assets have already been lost or are at risk.
Recordings at risks are things like student radio recordings on open reel tapes including performances from Alan GInsberg etc.; 1967 Sister Survey where coded responses from 130,000+ sisters were in an inaccessible file format.
Key challenges identified:
- Lifecycle management
- Digital archiving: collect and retain the assets (of critical importance to the future)
- Digital preservation: maintain these assets so that they remain accessible and usable
Recommendations based on analysis:
-Strategy, policy and organization
- add “digital” as new category of assets to University’s Strategic Plan for which superb stewardship is required
- move away from task-force or project based approach
- embed archiving and preservation considerations in business processes
-Storage and Cloud services
- immediate goal: reduce the use of direct-attached devices as a long term storage solution
- explicitly define treatment of data for services in the Cloud
LIbrary and Archive specific
- establish a digitisation and preservation centre, based at Hesburgh Libraries, to coordinate and serve campus needs
- make informed decision on archiving assets residing on the web & social networks
- build capability and transition to electronic records management
Recommendations were then prioritized using Prioritisation techniques
Now in the planning phase
Q: How are your relationships with various parts of the organization? Library? IT?
A: Nobody has been that rude to me … just yet. It’s important that people see me as part of the library AND part of the IT. Very important that I have support from top-down. And I’ve really taken some time to dig into the resources. I’ve also come across issues - digital requires cultural change.
Sustainability Program - is the Digital Preservation Program, but it was felt that “Sustainability” is more understandable
Starting point is understanding that Certification is beneficial. It’s rewarding for your own organisation. But it’s also beneficial for the preservation activities in the Netherlands in general. If you want to have a large cross-institutional infrastructure, you need to trust each other and it’s better if you can proof the trustworthiness. While Certification is currently voluntary, we except it might be required in the future, e.g. by research funders. Most Sustainability program partners are currently preparing themselves for the CTS (formerly DSA) or nestor Seal.
We have a roadmap to certification:
1. Selfassment score model (tool based, developed in conjunction with Flemish colleagues - tool asks basic questions like “how many objects do you have?”, “do you have two copies?” and also explains why these things are important - so in a way it’s a handbook as well)
2. Exploratory phase
4. Nestor / DIN
5. ISO 16363 Trustworthy repositories
DSA Survey was done asking those already certified how much time it took for them to receive the seal, what the hurdles were, if they intend on going for the other levels, …
Link to survey: http://www.ncdd.nl/wp-content/uploads/2016/10/201611_DE_Houdbaar_Report_DSA-survey_2016.pdf
Few people said they would go for the nestor seal, no one said they would go for ISO.
A huge achievement of this Program was that now a large digital preservation network in the Netherland exists with over 100 people.
Initially started in April 1998 as a personal project of Professor Koichi Hosoi
Objective was to create a research platform which allow scholars from multiple disciplines to study video games (e.g. economics, sociology, computer science, …) and to collect all types of resource about video games from hardware to software.
First Task completed in 2004: create a digital database for 1769 Famicom titles (Loaned from Nintendo) → no longer exist
3 fold approach:
1. Preservation of actual software and hardware
2. Preservation using emulator system
3. Preservation of playing screen images / filming
2003: Famicon Digital Library (FDL) - developed under the permission from Nintendo - the only outside party to do so (only 2 titles: Donkey Kong and Mario Brothers)
Launched Industry-Academic Collaborative Conference: Game++ Digital Ingeractive Entertainment Conference 2005 (brought together developers / creators from Atari, NES, Pacman, Super Mario, Zelda, Metal Gear Solid series, Half Life 2, etc.
Recording Play Images
In order to distinguish one title to the next, including the traits of each, recording visual image considered to be of significance. Aim at reusability for research, the game play control along with images of game players and the game play are recorded simultaneously and archived as one set of the game play record.
6263 Titles from approx. 14 consoles (PlayStation, SEGA Saturn, Super Famicom, PC Engine, FamilyComputer, PlayStations2, Dream Cast, Play Statio Portable, Nintendo DS, SEGA Mega Drive, Gameboy Advanced, Nintendo GameCube, Game Boy).
Status of data carrier/hw Video Game Preservation at Ritsumeikan:
Not emulated due to legal restrictions
- all products located at RCGS (3 rooms)
- one room designated for dedicated use of storage, 24C humidity 50% - this is for high priority preservation
- QR code placed on each item.
Since 2012 Game Archive Project has been selected as the official partner for creating game section of Media Arts Database, which currently includes:
38.042 console games
5.018 arcade games
1.623 PC games
In total: 44.683 titles
- project evaluating who collects Video games in Japan and beyond and of what years
(RCGS, Leipzig Univ., Meiji Univ., Strong Museum, NDL, Japan Game Museum)
- developing and analyzing ontology in Japanese video games titles (e.g. length of titles, number of hiragana, number of katakana, etc.)
- regional differences in perception of Japanese game titles
Q: what kind of strategy do you have for preservation of online games and apps like PokemonGo?
A: we have a master student currently doing some work on online games. Problem is version changes frequently, sometimes daily and you’re not even informed (e.g. patches). This is impossible to track and that’s a huge issue. Apps are probably even more difficult because there’s a higher server client dependence. Maybe for the online games we need to preserve them from a journalistic point of view - rather record and document experience etc. and not actual preservation of all version-ups. That’s most likely not possible unless the company will contribute to that.
Q: Do you see more commercial cooperations in the future?
A: Several years ago they gave us Donkey Kong because they thought it was old and there was no market - but since there have been re-releases and every game is still commercially available now. So no, I don’t see any more cooperations.

Q: Anyone uses wikipedia on top of Fedora?
A: Wikipedia pulling data, yes. As far as I know, no one has wikipedia reading and writing into Fedora. Theoretically it’s possible. Might need to implement locking to prevent multiple people editing at the same time.

.@vinaygo:"Just looking at header information in WARCs has helped longitudinal studies e.g. #webhistory #fileformat" #iPRES2017
WAT record is a WARC derivative, contains only metadata, stripped of main content.
A WAT file is a derivative file created from a WARC but more lightweight and containing only key data and not the full resource information (such as page text).

13:00-16:00 Tutorial 3 Understanding and Implementing PREMIS Karin BREDENBERG, Angela DAPPERT and Eld ZIERAU
Background and what is PREMIS
What is premis?
International de-facto standard for metadata to support the preservation of digital objects and ensure their long-term usability – if you want to support more services you may need more metadata. Implemented in digital preservation projects around the world, in commercial and open source digital preservation tools and systems.
PREMIS data dictionary: http://www.loc.gov/standards/premis/v3/
Digital objects must be self-describing.
Important questions: when you do your preservation metadata: where do put it and how do I encode it?
Using preservation pyramid from Priscilla Caplan
Availability: basis of being able to preserve. Object is in our control or in control of trusted accessible repository – cloud use depends on policy, legislation.
Identity: each relevant entity is persistently uniquely identified – file, work, person, organisation, licence – identifier type and identifier value
Understandability: file names not enough, files might not be readable –PREMIS offers ability to record physical structure, so does METS – can capture info like reading order to make sense, whether files are embedded in other files. Knowing about the logic to make sense – knowing title, etc to make sense. Need to know the context: where it came from – original source, related items.
Fixity: the object is unchanged – the order of 0s and 1s are the same, no bit rot over time or that it has been transferred properly.
Viability: the object remains readable. What data carrier is it stored on? Age of medium, date of recording, did I read and write on it a lot so it will decay sooner?
Renderability: able to render or execute the object – barrier of technology, lots of dependencies and need format information, rendering information (computing environment hardware software) – either you want to preserve the environment or you need enough information to see what the original was to see how it can be migrated to in a new tech situation.
Authenticity: digital objects are always undergoing object transformations and there is danger with changes like bit migration, content migration, replacing part of the rendering stack, forensic transformation actions.
Using PREMIS as a checklist: be able to think about what metadata you need for your repository to check if potential vendors can satisfy those needs. Understanding what your needs are according to policy, org context is very useful before checking vendors’ offerings.
