> Partly a question, and partly a suggestion for improvement: should HTTP PUT to the /data endpoint replace existing content in the graph? I'd like to suggest that it does, for the following reasons:
> * we already have POST to /data to add new content
> * it seems more consistent with the HTTP spec
> * it would support the use-case of 'get the current graph contents, edit it, put it back'
> Here's a test case:
> {noformat}
> ian@ian-desktop $ curl http://localhost:3030/foo/data
> { 
> }
> [~/workspace/jena-fuseki2] 
> ian@ian-desktop $ curl -XPUT -v -d '<http://example/foo> <http://example/p> <http://example/a>.' -H 'Content-Type: text/turtle' http://localhost:3030/foo/data
> * Hostname was NOT found in DNS cache
> *   Trying 127.0.0.1...
> * Connected to localhost (127.0.0.1) port 3030 (#0)
> > PUT /foo/data HTTP/1.1
> > User-Agent: curl/7.35.0
> > Host: localhost:3030
> > Accept: */*

> What I am suggesting is that the final GET returns a graph of one triple: :foo \:p :b
