Contributor Terms

Version 1.0 as amended on 12.Oct.2011

Thank you for your interest in contributing data and/or any other content (collectively, “Contents”) to the geo-database of the WELT2000 project (the “Project”). This contributor agreement (the “Agreement”) is made between you (“You”) and the Project and clarifies the intellectual property rights in any Contents that You choose to submit to the Project in this user account. Please read the following terms and conditions carefully.

  1. We respect the intellectual property rights of others and we need to be able to respond to any objections by intellectual property owners. This means that:
    1. (a) Your contribution of data should not infringe the intellectual property rights of anyone else. If you contribute Contents, You are indicating that, as far as You know, You have the right to authorize the Project to use and distribute those Contents under our current licence terms. If You do not have that right, You risk having Your contribution deleted (see below).
    2. (b) Please note that the Project does not have to include Contents You contribute in the Project, and may remove Your contributions from the Project at any time. For example, if we suspect that any contributed data is incompatible, (in the sense that we could not continue to lawfully distribute it), with whichever licence or licences we are then using (see sections 3 and 4), then we may delete that data.

Rights Granted

  1. Subject to Section 3 and 4 below, You hereby grant to the Project a worldwide, royalty-free, non-exclusive, perpetual, irrevocable licence to do any act that is restricted by copyright, database right or any related right over anything within the Contents, whether in the original medium or any other. These rights explicitly include commercial use, and do not exclude any field of endeavour. These rights include, without limitation, the right to sub-license the work through multiple tiers of sub-licensees and to sue for any copyright violation directly connected with the Projects rights under these terms. To the extent allowable under applicable local laws and copyright conventions, You also waive and/or agree not to assert against the Project or its licensees any moral rights that You may have in the Contents.
  2. The Project 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; CC-BY-SA 2.0; or such other free and open licence (for example, as may from time to time be chosen by a vote of the Project membership and approved by at least a 2/3 majority vote of active contributors.
    An "active contributor" is defined as:
    a natural person (whether using a single or multiple accounts) who has edited the Project in any three calendar months from the last 12 months (i.e. there is a demonstrated interest over time); and responds to a request to vote within 3 weeks.
  3. At Your or the copyright owner’s option, the Project agrees to attribute You or the copyright owner. A mechanism will be provided, currently a web page
  4. Except as set forth herein, You reserve all right, title, and interest in and to Your Contents.

Limitation of Liability

  1. To the extent permitted by applicable law, You provide the Contents “as is” without warranty of any kind, either express or implied, including without limitation any warranties or conditions of merchantability, fitness for a particular purpose, or otherwise.
  2. Subject to any liability that may not be excluded or limited by law, neither You nor the Project shall be liable for any special, indirect, incidental, consequential, punitive, or exemplary damages under this Agreement, however caused and under any theory of liability. This exclusion applies even if either party has been advised of the possibility of such damages.


  1. This Agreement shall be governed by English law without regard to principles of conflict of law. You agree that the United Nations Convention on Contracts for the International Sale of Goods (1980) is hereby excluded in its entirety from application to this Agreement. In the event of invalidity of any provision of this Agreement, the parties agree that such invalidity shall not affect the validity of the remaining portions of this Agreement. This is the entire agreement between You and the Project which supersedes any prior agreement, whether written, oral or other, relating to the subject matter of this agreement.
