If you are looking for a final set of all the documents, here they are:
- Contributor Terms - Individual contributors need to agree to these terms before contributing.
- Human readable summary of the Contributor Terms
- Database Contents License (DbCL) - Contributors waive all rights in the individual Contents of a Database licensed under the ODbL. In the text, 'Licensor' means the contributor and 'You' means the Foundation. This effectively means that end users of data published by the Foundation need to study only the ODbL rather than worrying about any special copyrights on individual elements of the database.
- Open Database License (ODbL) 1.0 This is the license under which the Foundation publishes the entire geodata set. End users of OpenStreetMap need to comply with this license.
- Human readable summary of the ODbL license
- Community Guidelines - Some of the terms in the ODbL need further clarifying in terms of geodata. This is a guide to end users created by the OpenStreetMap contributor community. It will evolve over time.
- 'We Are Changing The License' - Existing contributors will be asked to re-license their data under the new license, this gives them an overview of why.
- 'License Change Proposal' - this document is out-dated by gives a fuller overview of the perceived need for a license change and the primary goals.
- 'Why would I want my contributions to be public domain'. When new contributors sign-up, they can optionally tick a box "I consider my contributions to be in the Public Domain". This document gives them more information.
