The current Java implementation is GPL! That means that any derived work would need to be licensed with the same terms. So please, don't "get inspired" by that code base, don't even llok to it, since we'll have an intellectual property issue. If you find any example HDT file that does not parse with either the W3C Member Submission or the current spec http://www.rdfhdt.org/hdt-internals/ we should contact the authors of the format. Maybe we can start with that: collecting a set of files for the project testing. > I hope it's OK to stick to the original idea in the proposal.
