Split strings with SPARQL

Hi group,

I'm moving a lot of legacy data to RDF these days and in several, mostly
unrelated datasets I came across fields which had multiple values in it
which should be split up into multiple entries. Imagine multiple names
as an example.

This is quite common in SQL datasets which are not properly normalized,
which seems to be more common than I thought :-) Fortunately such field
often use separators so one could split that up pretty easily.

I googled around if there is anything I can do with SPARQL (to avoid
scripting) about this and found this posting:

http://answers.semanticweb.com/questions/19162/split-and-trim-strings-in-sparql

The most interesting answer is by Bob DuCharme, which showed how it is
done in TopBraid:

CONSTRUCT { :x :p ?member }
WHERE {
:x :p ?o .
?member spif:split (?o ",")

I found this a very useful function, is there anything like in in Jena?
Couldn't find anything documented so far.

regards

Adrian
