License

In accordance with the Terms of use, data in PANGAEA are published Open Access, preferably under a CC-BY license.



The license is explicitly defined in the metadata.

Under which licenses can data be archived in PANGAEA?
Licenses available from the drop-down menu in the Data submission form (Create Issue/License):
 * CC-BY: Creative Commons Attribution 4.0 International
 * CC-BY-SA: Creative Commons Attribution-ShareAlike 4.0 International
 * CC0: Creative Commons Zero 1.0 Universal

Most of the Creative Commons licenses are used in Version 4.0, which addresses sui generis database rights (SGDRs) in addition to copyright and the other copyright-like rights covered in earlier versions. Because SGDRs can impede a user's ability to share, reuse, and modify a work in the same way that copyright can, 4.0 makes it clear that these permissions apply to works that would otherwise be restricted by SGDRs as well. These version have no country specific variants. Older data were published under 3.0 version.

Additionally, PANGAEA can accomodate community-specific license agreements.

Data sets can be password protected (under moratorium) on request of the author. In this case the data can be accessed via a login which is available from the author and metadata are public.

In unpublished data sets (with status "in review", "questionable " or "validated") the license is not shown.

 * Because PANGAEA does not specialize on software archivation, this license is not widely used (and cannot be chosen from drop-down menu in the data submission form)
 * In case you wish to license your submitted software under this license or any other Free Software compatbible license (e.g., ASF-2.0, MIT, BSD, LGPL,...), indicate it to the editor

Summary
Recommendation by PANGAEA is to use CC-BY, but also CC0 is possible. In general all CC licenses are allowed, but NC and ND licenses are discouraged as they limit usage. The chosen license must be in compliance with possible terms of usage inherent to the submitted data. In case of conflicts, data submissions cannot be processed.
