PUBLIC MARKS with tags c & photo

Xapian is an Open Source Search Engine Library, released under the GPL. It's written in C , with bindings to allow use from Perl, Python, PHP, Java, Tcl, C#, and Ruby (so far!)

This utility uses the photos.getInfo API to interpret the description fields and the tags for a photo URI into RDF triples. If raptor is present, it will be used to provide proper serializing to RDF rather than the built in and hacky ntriples/turtle output. Machine tags when they are found are scanned for xmlns:prefix=uri and then all other machine tags with that prefix turn into triples. Several prefixes are also pre-defined by the library to automatically get turned into triples without an xmlns, such as blue:, cell:, filter: and geo:. Non-machine tags are not yet interpreted.
