In W3C style, "status of this document" isn't numbered. Perhaps that's one of the small ones on your TODO list already... And I have a suggestion about the Intro... "Since there are no formal standards for an RDF query language, developers in industry and in open source projects have created many query languages for RDF data." Hmm... I don't think the lack of standards is the reason they created those languages; they created those languages because they're useful. How about: 1. Introduction The W3C's Semantic Web Activity RDF is based on RDF's flexibility as a means of representing data. Developers in industry and in open source projects have created many query languages for RDF data. While there is considerable overlap in functionality, it may be only a small exaggeration to say that there are as many different methods of accessing remote RDF storage servers as there are distinct RDF storage server projects. Even where the basic access protocol is a standard—HTTP, SOAP, or XML-RPC—there isn't much common ground upon which generic client support to access a wide variety of such servers might be developed. The existing languages also exhibit a range of extensibility features and builtin capabilities, including inferencing, distributed query, and domain-specific semantics. The use cases below characterize the most important and most common motivations behind the development of these query languages and protocols. They inform the decisions between requirements, i.e. critical features a standard RDF query language and data access protocol, and less urgent objectives. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ see you at the WWW2004 in NY 17-22 May?
