In your example, it's {{PUT}} on {{/ds/data}} is a quads operation and it
clears the dataset . All named graphs will be removed.
If you want per graph control, it'll need to use {{?default}} or {{?graph=...}}

Ah, good point. Thanks!

> Reporter: Ian Dickinson
> Labels: fuseki2

> 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
