Thomas, Thanks for noticing this RDf file issue. I have uploaded a latest RDF file http://www.w3.org/ns/ma-ont.rdf When I paste the RDF document into the text field of the RDF Validator http://www.w3.org/RDF/Validator/ It validates. but when I validate using the "Check by URI" with http://www.w3.org/ns/ma-ont.rdf It responds the following error "An attempt to load the RDF from URI 'http://www.w3.org/ns/ma-ont.rdf' failed. (Undecodable data when reading URI at byte 24574 using encoding 'UTF-8'. Please check encoding and encoding declaration of your document.) " I believe, there must be a W3C server issue with the encoding, I don't really understand the problem. I have also updated the spec with the latest RDF file http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/PR/ and for convenience, I have also added a link in the spec to the file http://www.w3.org/ns/ma-ont.rdf Best, Thierry.
