Proposed SPARQL Endpoint

hi,

as mentioned in previous mails, we've setup a first draft of the proposed
upgrade of rya's sparql endpoint.. again note, that we've setup a small
debug/demo maven project using a sesame memory store to demonstrate the
proposed changes. if the proposed upgrade of the sparql endpoint is welcome
we would incorporate this with existing rya code to include all required
rya features.
features:

1. full support for content-negotiation (essential within the
linkeddata/semantic web realm)
2. SPARQL Service Description
3. more HTTP Status Codes (202 accepted, 400 bad request, 200 ok)
4. all RDF serialization formats available natively from sesame
5. customizable web endpoint (via a sesame MAVWriter (ModelAndView) + JSPs
+ Styles)
6. valid XHTML for the endpoint
7. valid XHTML+RDFa in a browser for construct queries
8. a future rdf4j upgrade will not seriously affect the whole endpoint

the project is very easy to build and you can checkout all features on your
local machine easily (examples are provided). the maven build will include
a tomcat hosting this sample endpoint, descriptions and code can be found
here:

any feedback, pointers, comments and wishes are highly welcome!

note: that wouldn't be a problem..

when merging those two efforts, old url mappings could still made be
available.. and also the user authentication would be implemented.
this is a first draft showcasing what would actually be expected from a
modern sparql endpoint..

I think we should probably keep supporting the old end point as well for legacy users.
