I believe that, in order to properly/correctly solve this issue, SPARQL implementations could provide a mean to get for each bnode in a SPARQL query answer the data graph node *bound* to it, e.g., for each SPARQL query result  there could be a table with bindings: <result-bnode, data-graph-node>.
IMHO it would be wrong (and not necessary, in this case) to give persistent identifiers to bnodes.

I'd really like to see mandatory persistent blank node identifiers in
SPARQL - so I can easily do followup queries for blank nodes from a SPARQL
result. Is this a big deal? I think some triples stores can already do this.
Which issue do I upvote to get this?
