3. Finalise today's agenda

4. IGN, French national mapping agency (Emilie)

Are considering using OSM data for verification purposes of administrative boundaries (nothing else for the time being).  Background: OSM has collated boundaries separately from the tax authority and resolved some discrepancies between different datasets.

1) Informally we have no objection to use of OSM data solely for verification purposes, provided that we do not not create any loop-hole for copying/derivative databases. I.e. if compare but not take, share alike is not triggered. We will consider some formal wording on this issue Mike - draft wording for discussion. We have discussed this before re UMP in Poland.

2) If IGN want to go the next step and use, (“take”), OSM data and create a derivative, we note that ODbL is already in use in France for government data and strongly encourage IGN to use the same license.

5 Content License for ODbL

We need to clarify the role of the DbCL in our ODbL licensing. We have a reference in our contributor terms (*) but not on our copyright page.

* Clause 3:  “OSMF agrees that it may only use or sub-license Your Contents as part of a database and only under the terms of one or more of the following licences: ODbL 1.0 for the database and DbCL 1.0 for the individual contents of the database; ...”

6. Trademark and branding IP policy (Simon)

7. DMCA take-down procedure documentation

No action, we are awaiting some input from legal counsel.

8. ODbl-Compatible Licenses

Still no useful answer from  OpenDataCommons coordinating group

9. Dynamic Data

Briefly discussed. This is the issue of whether dynamic data, (e.g. how full a car-park is at any time of day), of no formal  interest to OSM is used in conjunction with  our static data, (e.g. location of car-parks within a city), whether share-alike is triggered on the dynamic data. One interesting concept that came up is “related data”. Dynamic data is not related to mapping data and therefore cleanly outside the share-alike trigger, such as have a clear separation between text and a map in a book. We will put this to legal counsel.  For the record, it should be noted that LWG will take no position on this until the OSM community have a chance to discuss it.

10. AOB

  • UK agencies publishing data under OS Open Data license rather than OGL. LWG strongly against this, that is what the OGL is for. Mike will make this position clear to ODUG
