Hi, I have the following feature suggestion for the WG: Feature: Query By Reference Feature Description: Extend the SPARQL protocol to allow queries to be referenced by URL rather than being included in the query string. The query would be found by dereferencing the supplied URL and parsing the results. Just as an endpoint may decide to not process a query if its dataset is unacceptable (e.g. if query is over arbitrary data and endpoint used a fixed data set), the endpoint might also choose to not process queries of this form. This allows developers to address concerns over the protocol being used as a vector for potential DoS attacks. Caching of retrieved queries would also mitigate this. Example: E.g: /sparql?query-uri=http://www.example.org/queries/test.rq Existing Implementations: I have implemented support for this in the XMLArmyKnife endpoint (http://xmlarmyknife.com/docs/rdf/sparql) Use Cases: Allow queries to be more easily published and shared between developers. Cheers, L. -- Leigh Dodds Programme Manager, Talis Platform Talis leigh.dodds@talis.com http://www.talis.com
