RDF Application Samples

Using DC: Ref. Examples 30-32 in RDF Primer. We’ve already talked of Dublin Core Metadata Initiative. Take a look at Dublin Core Metadata Element Set. DC community tools and software

Use in/with programming languages (Example 33) : see W3C SVG (scalable vector graphics markup language). In an Airplane Under the Sea » SVG Viewer Demo If interested in SVG, try open source Batik Toolkit

Adobe’s XMP (Extensible Metadata Platform) for inclusion of indelible markup with media. See & listen to Gunar Penekis’s talk on The XML Metadata

Platform (XMP) at Ontolog. PRISM: Publishing Requirements for Industry Standard Metadat

RDF Applications: SEARCH AROUND

RDFWeb: Friend of a Friend (FOAF) developer site FOAF applications as we’ve covered in RDF Intro Have you set up TouchGraph Photos application in

Facebook yet? Also see TouchGraph homesite. While there, try graph

your homesite URL. Play with the graph. ESW Wiki: check Applications tab Run “RDF application” at Google. Run “RDF application” at Google Scholar.
