RDF-ISSUE-21 (Shared Node-IDs): Can Node-IDs be shared between parts of a quad/multigraph format? [RDF Graphs]

http://www.w3.org/2011/rdf-wg/track/issues/21

Raised by: Sandro Hawke
On product: RDF Graphs

Given N-Triples:

_x: <http://example.org/p1> 1 <http://example.org/id1> .
_x: <http://example.org/p1> 2 <http://example.org/id2> .

if id1 and id2 were merged, would the resulting graph have three nodes or four?

Use cases for allowing them to be shared include:

- SPARQL default graph being the merge of the named graphs
- proof trees, details of inference over graphs
- highlighting/annotating subgraphs, for provenance
