add support for XSPARQL
-----------------------
Key: CLEREZZA-317
URL: https://issues.apache.org/jira/browse/CLEREZZA-317
Project: Clerezza
Issue Type: New Feature
Environment: all
Reporter: Henry Story
XSPARQL [1] is the RDF equivalent of XQuery, and is in fact built on top of
XQuery usually.
It can be used to create XML from rdf stores using SPARQL like queries (called
lowering) and transform XML into RDF (called lifting).
This could be used for two purposes in Clerezza:
1. Lowering: for generating XHTML or other XML formats
this would be in addition to Scala Server Pages. Some things that could be
done more easily than in SSP is get information from different graphs.
2. Lifting: for transforming XML into RDF
This is where XSPARQL is really without equivalent. This can help write
transforms for any XML format into RDF for the store, making it much
easier to build integrating layers with existing web services
The DERI Team in Galway has just published the java code [2].
