Hi, I'd like to make the following feature suggestion/raise an issue with the WG: Feature: Support contextual links from all query responses Feature Description The SPARQL XML Results format currently supports a <link/> element allowing references to additional metadata to be included in the response. However this feature is limited as there is no way for a client to select between the possible alternatives. A "rel" attribute similar to HTTP would be one way to enable this, as would allowing additional elements from extra namespaces to be included in the response. A typical example of using this feature would be to link back to the original endpoint, or to licensing metadata associated with the request. However currently this feature has no equivalent for CONSTRUCT/DESCRIBE queries. It is potentially legal for an endpoint to include additional statements that refer to the response document, but it is more likely that clients will simply treat these statements as part of the results, rather than separate metadata about the result document. Example: Allow, e.g.: <link rel="license" href="..."/> and/or <rdf:Description rdf:about="..."> ...statements about response document... </rdf:Description> ... query results ... Example Implementations None that I'm aware of. Use Cases * Make the protocol more RESTful by allowing hypertext linking, from all result formats * Allow linking to, or embedding of license statements relating to the data in the results * Allow linking to a service description for the endpoint and/or VoiD description of the dataset Cheers, L. -- Leigh Dodds Programme Manager, Talis Platform Talis leigh.dodds@talis.com http://www.talis.com
