OpenResearch:Copyrights

The content on is meant to be used freely (in a concrete legal sense specified below) by anybody who is interested. For this reason, we employ the following scheme of dual licensing that ensures possibility of broad reuse. If you do not agree with the below license terms, please do not contribute your text to this wiki. Also, please ensure that all contributed content respects the following license terms.

Licensing for text documents
All content of is licensed under the GNU Free Documentation License (GFDL) in version 1.2 of November 2002.

The full text of this license is to be found at Wikipedia. Wikipedia also provides an informal (and not legally binding) interpretation of this license.

Although GFDL is a free license, it imposes various restrictions on the possible reuse of content. Especially, derivatory works and publications must be available under the same license. This can be an obstacle to some envisaged uses of this wiki, and we therefore add the following alternative license:

Unless explicitly rejected in the respective article, all content of is also licensed under the Creative Commons Attribution License 2.0 that can be found online at http://creativecommons.org/licenses/by/2.0/de/deed.en_GB.

This enables users to use the content of in publications of different licenses or even commercially, given that the original authors and the source "" are given credit. The suitable way of realising this requirement is to provide a link to the originial source article on as part of derivative documents (e.g. web pages), together with the statement that content was (in part) derived from that source.

This dual licensing applies to most pages, with the exception of those that have been copied from sources that do not allow licensing under the above Creative Commons license. In particular, those are pages which contain content copied from Wikipedia, as will be discussed in the next section.

Copying content from Wikipedia and other GFDL documents
If you want to refer to content in Wikipedia, you can simply create a link by writing the title of the desired article

possibly in the form

text to display

and we strongly suggest to do this instead of copying content. If you still copy text, you are (partly legally) required to


 * 1) attribute the original source by adding a link to the original article on Wikipedia (e.g. at the page bottom),
 * 2) point out that a list of original authors is also found at Wikipedia,
 * 3) state that the given article as a whole is no longer licensed under the above dual licensing scheme, but that GFDL is the only possible license (you may want to add why, so that others can use at least parts of the article under the Creative Commons license).

These remarks also apply to other content that is licensed under GFDL only.

Weeeee, what a quick and easy soltiuon.

Licensing of the exported OWL, RDF, and other metadata
The exported OWL/RDF is generated automatically by from the textual content entered by the users. In principle, it could still contain short passages of text that are subject to copyright claims form other parties. will not make any claims on the generated RDF provided that it does not contain text passages that are longer than 256 characters, and grants permission to use the exported RDF at the user's own risk. does not guarantee the factual correctness of the exported RDF, or its fitness for any particular purpose.

Similar regulations apply to other metadata exports generated by.
