Agenda & Minutes
Present: Simon Poole, Oliver Kühn, Richard Weait, Michael Collinson
Minutes by: Michael
1. Adoption of Minutes of last meeting
Note: This minute link is for LWG members only. A read-only version is normally available at http://www.osmfoundation.org
2. MATTERS ARISING (open action items from previous meetings)
3. Finalise today's agenda
4. DMCA take-down procedure
Following feedback from the board, LWG will expand its initiative to produce public documentation describing what happens after a take-down notice is received to formally documenting the process for presentation to the board. This will act as an ISO 9000-like process whereby areas of risk can be pinpointed.
The following is a link to a draft document for editing by LWG and DWG members. It will be made public once some legal clarification is made on a couple of areas:

6 ODbl-Compatible Licenses
A question from a German government agency: How is a compatible license decided? Who decides it?
ODbL 1.0 states:
“4.4 Share alike.
a. Any Derivative Database that You Publicly Use must be only under the terms of:
i. This License;
ii. A later version of this License similar in spirit to this License; or
iii. A compatible license.
If You license the Derivative Database under one of the licenses mentioned in (iii), You must comply with the terms of that license.”
Note that ODbL also states:
“[4.4] d. Share Alike and additional Contents. For the avoidance of doubt, You must not add Contents to Derivative Databases under Section 4.4 a that are incompatible with the rights granted under this License.
e. Compatible licenses. Licensors may authorise a proxy to determine compatible licenses under Section 4.4 a iii. If they do so, the authorised proxy’s public statement of acceptance of a compatible license grants You permission to use the compatible license.”
LWG will ask OKF/OpenDataCommons opinion.
7 Dynamic Data
Simple example: The capacity of a car-park is static (or at least non-realtime) data. The number of cars parked in it at any one time is dynamic data, it is not of interest to OSM ... can it be formally exempted from Share Alike?
We look at creating a new Community Norm. This will need evolving with OSM community.
We also need to the address the issue of Community Norms changing in the future. Where does that leave users of data? They can probably continue to use data pulled from the OSM database before the change is made, (grandfathering), but should we also lessen their risk by adding a sunset statement, (“and you may continue using data for two years”)?
“Report on the International Expert Meeting on Crowdsource Mapping for Disaster Risk Management and Emergency Response carried out in the framework of the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER) December 2012” now available at
Sharing of data and licensing was a major concern and paras 50-54 deal directly with it. (Michael Collinson attended the 3rd - 5th December 2012 session as did Kate Chapman of HOT).
Next meeting: Tuesday March 5th at 19:00 GMT/UTC
