Hello,
I'm a software engineer for the Creative Commons and am working on our on-line license/RDF validator. We're currently working on adding <link> support for RDF retrieval, due in large part to Wikipedia's decision to use CC metadata to describe the FDL license. We have intial support working, but when we test with Wikipedia, we get a 403: Forbidden.
Our system parses the page and attempts to retrieve the metadata file seperately; specifically, http://en.wikipedia.org/w/wiki.phtml?title=Main_Page&action=creativecomm... for the Main_Page.
Does Wikipedia have non-browser requests for the metadata blocked? Is there something we need to do in order to retrieve the metadata? Thanks for any help you can provide.
Nathan R. Yergler
