4. Ed Avis research - Does copyright apply to OSM data?

Ed has circulated to the LWG the report received from his US contact. UK one still to go.

5. Old and new LWG members

Oliver and Dermot are joining us from the board, with Oliver being the official board representative replacing Henk.  Henk will continue to join meetings and assist on a part-time basis.  Mike proposed a vote of thanks to Henk for all his work and for attending almost every meeting over a period of at least two years. The vote was carried unanimously.

6. Weekly or bi-weekly meetings?

For conformancy, we will go to back to a weekly, keeping some of them short and only dealing with some of our routine items once every two weeks.

7. imports

There has been correspondance between Michael Collinson and requesting permission to continue including their data given: that CC-BY requirements for users of OSM data to equally attribute all contributors, the impracticality of that and the fact that we will no longer be requiring such secondary attribution as teh result of a switch to another license. As a result, such permission has been given. point out that this only applies to datasets licensed under CC-BY (2.5 or 3.0).

The exact permission has been summarised as below. have actively reviewed earlier versions of the page and have been given opportunity to say if it is not accurate. So far, they have not done so.

“Contains data from Australian government public information datasets. The original datasets are available from the Australian government data website under Creative Commons - Attribution 2.5 Australia (CC-BY) and Creative Commons - Attribution 3.0 Australia (CC-BY). We have also been given explicit permission to incorporate and publish such CC-BY licensed geographic coordinate datasets under a free and open license, including the Open Database License, provided that primary attribution is made here and that each dataset used is also listed here in the format Dataset Name, Date Published, License, Agency Name, originally retrieved from “

8. ODbL implementation

  • Report

Voluntary accepts from older contributors are over 45k.  Voluntary accept rate is about
50/day.  Including new registrations, 238k+ users are using the new terms.
There was a small surge of 7 declines about three weeks ago, and three previous declines who have
since reconsidered.  Declines are 352 and remain below 0.8%

9. Database re-build

Mike has kicked off a document to capture technical needs that have come up in LWG conversations and related suggestions and questions that have come from Frederik Ramm and others. We can move it to when it has some structure.

10. Hall of Shame


These are *alleged* cases of violation of OSM copyright.


11. AOB

  • South African government data (Chief Directorate : National Geo-spatial Information, in the Department of Rural Development and Land Reform)

NGI has accepted Lance Burger draft but added some wording of their own.  Mike has reviewed. One change needs technical input as it potential puts a burden on OSMF to report to NGI changes made to data that  they have contributed.

12. Henk

  • AND. Henk has had a face to face to with AND, who contributed Netherlands, China and India data. AND is looking at strategic re-positioning. They have looked at the new license and were interested in difference between with collective and derivative databases. They will come up with some use-cases to further discussion.

Next Meeting:

Tuesday Oct 25th 11am PST / 14:00 EST / 18:00 UTC / 19:00 BST(UK) / 20:00 CEST AND/OR a date/time to suit Australian time zone.
