Standard project directories initialized by cvs2svn.
Added some dummy files.
Added a first example.
Added the lowering example for foaf.
Added xquery rewriting of foaf2xml_lowering.xquery version and
some typo fix in the xsparql version.
*** empty log message ***
XSPARQL
Remove stupid .svn stuff.
Fixed classpath
Fix classpath
Some fixes in the RDF. Also committed an XML version, since Joseki doesn't
seem to like Turtle/N3.
Pre-final, tested version.
The syntax we shall use for multiple variables in the lowering
syntax shall be like in select, i.e.

  for ?v1 ?v2 from

instead of

  for ?v1i,?v2 from

As we learned in the discussions today, "," rather stands for cartesian
product in XQuery.
New file (nonfunctional).
This should work somehow, but the full xquery grammar is just too big:
(a) either stay with this subset of xquery, (b) implement the whole
stuff, or (c) tweak the syntax s.t. we don't need to parse real xquery
flwr expression and only have to deal with xsparql for loops and dump
xquery flwr to stdout.
Put stuff in the paper and worked on examples.
Update xsparql lowering rewriter.
Fix the input parsing by handling ignored parts of the input outside the parser.
Small fixes in the rewriter.

Missing things:
- Testing (sparql endpoint setup)
- Accommodate the rewriting module to deal with substituting the
  possibly bounded vars in the graph pattern.
Fix example's syntax errors.
Namespace declarations use = instead of :=, grml.
Do not use fn:encode-for-uri, instead, encode the sparql query using python's urllib: this is easier to test the generated query.
