this may be way off base - I'm only getting up to speed on RDF
querying. Is there any reason why the Fresnel "Result Tree" can't just
be an enhanced version of the SPARQL query result format
(
http://www.w3.org/2001/sw/DataAccess/rf1/). For example, just add a
label attribute to head elements to support labels?
In the SPARQL standard they say: ""Results can be thought of as a
table, with one row per query solution. Some cells may be empty because
a variable is not bound in that particular solution."
An example in the SPARQL standard
(
http://www.w3.org/TR/2005/WD-rdf-sparql-query-20050419/#select) with
added label support?

</result>
</results>
