PSIMeter-Showcase: RDF-ize the flickr API

This is a demo to show alternative ways to RDF-ize the flickr API regarding machine tags. Three approaches are used to achieve the same result: to create an RDF graph that contains the requested property along with the specified value.

Select execution method

Approach A
(may take some 10s)

... uses the flickr API to retrieve photos of a user tagged with a certain machine tag, and adds the used tags to each photo, finally converting the result into RDF using a local XSLT.
Approach B
(may take some 50s)

... uses the flickr API to retrieve all public photos of a user, and uses local XSL transformations to generate the RDF graph;
Approach C
(may take some 2min)

... uses the flickr API to retrieve all public photos of a user. Then, for each photo an external service is invoked to generate the RDF graph.
