RDF Path Languages And Templating
There have been many RDF Path languages. This is a non-authoritative list, begun because people have asked about them (or, indeed, invented them) periodically. RDF Path languages and template languages are used to transform RDF triples (or graphs) into another form, typically a web interface in HTML. This list helps you to find out which template languages and Path languages exist, perhaps with an implementation of it.
If you want to transform RDF to XML/HTML/Text, read on! You may also wish to read a 2007 survey of the state of the art of RDF templating, in the form of a morning-long discussion on #swig.
Versa
http://www.xml.com/pub/a/2005/07/20/versa.html (query only)
N3 Paths
http://www.w3.org/2000/10/swap/doc/Shortcuts.html (expressions usable as queries)
RDF Path
http://infomesh.net/2003/rdfpath/ (SBP) http://logicerror.com/RDFPathProposal (AaronSw) http://zoe.mathematik.uni-osnabrueck.de/QAT/RDFPath/Quick/Quick.html (Stefan)
None implemented (?), but many good ideas here, some of which can be found in other implementations.
RDF Twig
http://norman.walsh.name/2004/projects/rdftwig (outputs XML)
Provides XPath extension functions (for Saxon or Xalan, in Java) which lets you access RDF from XSLT. Roughly, one can create trees (breadth or depth first) from part of a graph, and then navigate over it using XPath. Uses Jena.
Graph Path
http://www.langdale.com.au/GraphPath/ (query only; but nifty)
ReoPath
http://www.xulplanet.com/ndeakin/arts/rpath-fns.txt (query only). See http://www.xulplanet.com/ndeakin/arts/reopath/rpath-templates.php for templating.
TreeHugger
http://rdfweb.org/people/damian/treehugger/introduction.html (outputs XML)
Tricks XPath into working over a Jena RDF graph (including RDFS and OWL inferred). XQuery and XSLT (1.0 and 2.0) support thanks to Saxon.
RDF Templates
http://www.semanticplanet.com/2003/08/rdft/spec (demo broken; outputs XML?)
RxPath
http://rx4rdf.liminalzone.org/RxPath (RxSLT can presumably output XML)
FSL
http://www.w3.org/2005/04/fresnel-info/fsl/ (language-agnostic output)
FSL implementations for Jena 2, Sesame 1.2.x and Sesame 2 are available. IsaViz also features a visual FSL debugger.

Wilbur Query Language (WilburQL)
Central to the Wilbur toolkit is a path query language.
