WWW::DataWiki - RESTful read-write RDF repository
WWW::DataWiki is a RESTful read-write RDF repository. Powered by Catalyst, RDF::Trine and RDF::Query, it provides you with a wiki-like site where each page, rather than being a textual document is an RDF graph (actually, technically it's an N3 graph, so supports a slight superset of RDF).
Graphs are versioned, and each graph (each version in fact) acts as its own SPARQL endpoint. HTTP content negotiation serves up graph data as HTML, Turtle, RDF/XML, JSON; and query results as HTML, XML, JSON, CSV or tab-delimited data.
WWW::DataWiki is fully RESTful, using HTTP GET to retrieve the graph, HTTP PUT to replace the graph with a new version, HTTP DELETE to replace the graph with an empty graph (and there may be an option in the future to delete the graph and its entire history), HTTP POST to append RDF data to the graph, and HTTP PATCH to alter the graph using the SPARQL Update language. (SPARQL Query and Update can also be tunnelled over POST; and SPARQL Query can be tunnelled over GET.)
WWW::DataWiki exposes graph history using the HTTP headers described at http://www.mementoweb.org/.
WWW::DataWiki offers some rudimentary support for RFC 2324.
In the current release there is very little user interface, and to manage graphs you probably need to use a command-line tool like
There is currently no support for authentication or access control. You may be able to use external forms of access control.
