​

  • Aim: Allow actual data interchange between organizations by providing open licensed shared data models according to the principles of agile standardization

​

  • Smart Data Models is a collaborative program to provide data models for digital twins and data spaces
    1. Free and open-licensed data models for digital market (0€ cost)
    2. Multisector
    3. Based on real use cases and adopted open standards. Collaborative.
    4. At market speed
    5. Customizable to local needs
    6. Compatible with linked data

Glossary

5

  • Domain: Mostly a full sector of activity (i.e. Smart cities, Smart Agrifood)
  • Data model: Technical representation of a business object1 or entity
  • Subject: A subset inside a domain (i.e Streetlightning in Smart cities or device and Agrifood in Smart Agrifood)
  • Repository: Set of files in a directory controlled by a versioning system (i.e. git). It can be available online (i.e. github.com)

​

1 Business object refers to any entity related with the activities of the topic

Quick FAQ

9 of 20

1.- What is Smart Data Models program.

Smart Data Models initiative is a collaborative program to provide multisector agile standardized free and open-licensed data models based on actual use cases and open standards

​

2.- Who supports the program.

Currently FIWARE Foundation, IUDX, TMForum, and OASC are its steering board members. Other 120 organizations have already contributed.

​

3.- Can I use these data models for free?

Absolutely. They are open-licensed allowing you free use, modification, and sharing.

​

4-. Where do these data models come from?

They are based on real case scenarios or mapping of adopted and open standards

​

5.- Do I have to use the FIWARE platform or the NGSI standard to use them.

Not at all. They are compatible with it but we also export in several other formats (JSON, JSON-LD, CSV, SQL, DTDL, etc)

​

6.- I want to contribute with a new data model. What should I do?

Contribution is done by making a PR on the repositories. It would be good you have a look at the contribution manual (https://bit.ly/contribution_manual). You only need to create a JSON schema and provide some examples of use and one example. If you are not familiar with JSON schema this tool and these videos will help you.

7.- I guess that I need some support for creating the data model. How could I find it?

You can apply for the incubated repository where most of the data models are drafted before being approved. Just click on the green button on the front page or this link. See what is in progress on this list. You can always contact us or drop us an email.

​

8.- How could I find a data model?

The search tool allows you to search every property, data model, description, etc.

​

9.- My organization is willing to be part of the Steering Board. What do I need to do?.

A MoU is required and it is possible to collaborate globally or for some of the domains (environmental, robotics, etc). Let’s start with a mail at info@smartdatamodels.org

​

10.- How to deal with units of the attributes

NGSIv2 include units in the metadata associated with any attribute stored, while NGSI-LD has a built-in subproperty named UnitCode where the units should be included. For some of the attributes, there are recommendations about the units to be used.
