Graphs Task force

Skolemization of blank nodes: Revisit Steve Harris' proposal:

[[ Systems wishing to skolemise bNodes, and expose those skolem constants to external systems (e.g. in query results) SHOULD mint fresh a "fresh" (globally unique) URI for each bNode.

All systems performing skolemisation SHOULD do so in a way that they can recognise the constants once skolemised, and map back to the source bNodes where possible.

Systems which want their skolem constants to be identifiable by other systems SHOULD use the .well-known URI prefix. ]]

...which has received cautious approval on the mailing list.

Sandro's alternative proposal iterated by the Skolemization breakout at FTF1 was:

[[ If systems are going to reveal Skolemized bnodes, without doing damage to the graph, they MUST use a fresh URI (per bnode) and SHOULD follow the form http[s]://[domain]/.well-known/genid/[locally-uniq-id][#] or tag:[domain],[year]/.well-known/genid/[locally-unique-id] (or, someday, genid:...). Such IRIs are considered more disposable. "genid" to be reg'd with IETF. ]]

...but registering genid: at the IETF was determined to be infeasible in the time we have.

Cleanup Tasks

  • Leftover issues: There is a RDF active issue list left over from the previous RDF WG that has "postponed" issues. We may want to look at these to see if there are anything the new RDF WG would want to pick up. ISSUE-7.
