I rewrote the ARC SPARQL Parser for PHP[1] this week.
The current version (v0.2.0) covers the SPARQL query
language features of the WD of Nov 23 2005[2]. There
are probably still some bugs in it as the parser was
manually written, not auto-generated from the grammar
rules. The gain of this approach is that turtle
abbreviations are expanded on the fly, and nested
patterns can partly be flattened to facilitate further
processing of the generated information.

Additional ARC components to turn the parsed
information into useful SQL statements are already
in the works and should be available soon.
