PROV-ISSUE-169 (TLebo): Motivating provenance services in PAQ [Accessing and Querying Provenance] http://www.w3.org/2011/prov/track/issues/169 Raised by: Timothy Lebo On product: Accessing and Querying Provenance "3.2.1 Specifying Provenance Services" has a note: "This is a new proposal. It needs to be reviewed as to whether it is useful." I didn't see the request to put this in, but I'd like to offer some independent motivation. Some capabilities that a provenance service could provide that a "baked in" rel link could not provide: 1) Send me (via POST) the file (or its cryptographic digest) back, * I'll find you the "closest" document I know about (in case yours was changed) * I'll point you to all newer versions of what you have. * I'll point you to others that have done something with what you have. Content-based manipulations can not be handled by hard coded rel links, but services can provide some assistance (through heuristics) that can inform the consumer about what they _have_, as opposed to what was _given_ at some point in the past. Thanks, Tim
