W3C does not take a position regarding the validity or scope of any intellectual property right or other rights that might be claimed to pertain to the implementation or use of the technology, nor the extent to which any license under such rights might or might not be available.

Summary of patent statements for the RDF Core deliverables

This table summarizes patent statements for from RDF Core Working Group members who are in good standing and those in not in good standing. Either these members have provided patent disclosures and license commitments statements or have stated when joining the RDF Core Working Group that they do not have intellectual property rights relating to the working group. The 'license summary' column is a W3C Team characterization of the Member's statement into one of three general types of licenses: 1) Royalty-free, 2) Reasonable and non-discriminatory terms (RAND), or 3) no license offer because the Member claims it has no relevant patents. The RDF Core Working Group Intellectual Property declaration is the same as all working groups charted under the Semantic Web Activity and must be available on a royalty-free basis. A 'no license' in this case is by explicit default a declaration of Royalty-free. This summary is not offered to suggest the exact licensing terms. The precise terms of any license, however, are governed entirely by the Member's statement.
