PUBLIC MARKS with tags api & curl

Flickcurl is a library for calling the Flickr web service API, handling the API signing and the token management plus providing wrappers for some of the APIs.

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.
