Parsing RDFNode.toString()-s (back) to RDFNodes -- or parsing GROUP_CONCAT to RDFLists

[Martin G . Skjæveland]

Hi all,

in my application there is special support for lists (without going into 
further detail), and I would like to be able to have SPARQL queries that 
return lists. Since this is not supported in SPARQL, my idea is to 
exploit and consider GROUP_CONCAT "columns" in SPARQL result sets as 
lists and split and parse these part of the split to an RDFList (of 
RDFNodes).

Does this sound reasonable? Is there parsing functionality in Jena to 
handle this already? Perhaps there is something like  RDFNode 
parse(String)  which parses strings on the same format as 
RDFNode.toString() would produce back to an RDFNode?

Thanks!

Martin
