The Open Database License (ODbL) v1.0 “Release Candidate” is now available at:

http://www.opendatacommons.org/licenses/odbl/

This updated version of the license incorporates a whole set of changes arising out of the earlier comments period and the main changes are summarized below.

As the naming suggests, we believe this text is now very close to a “production-ready” 1.0 license. To allow interested individuals and communities time to review the latest set of changes, as well as to provide an opportunity to catch any last minute “bugs”, there will be a 1 week comment period starting today and ending at midnight next Wednesday (6th May). Full details on how to comment can be found on the ODbL home page.

In preparation for the 1.0 release we have also prepared detailed instructions on how to apply the license which can also be found on the ODbL home page. Any feedback on these is also very welcome.

Finally, we’d like to take this opportunity to say a big thank-you to everyone who contributed to that process as well as a special thank-you to Jordan Hatcher, advisory board member and the person primarily responsible, not only for creating the original version of this license, but preparing this latest revision.
