ramm.x – Example This still image contains embedded Exif metadata. Using the RDFizer service http://www.kanzaki.com/test/exif2rdf , an RDF/XML representation of the Exif metadata ( exif_example.rdf ) can be obtained. Aim : Deploy the Exif metadata with ramm.x in an XHTML document Result : exif_example.html
Another RDF-based multimedia description vocabulary, as, e.g., hAudio RDFa ;
A declarative vocabulary – just as other standards ( SPARQL , GRDDL , etc.) standardise not only a vocabulary, but also behaviour, or put in other words: operational semantics. Hence, classes and properties are defined along with their procedural impact;
A replacement for other technologies, nor can it exist on its own; it always needs a host language, e.g., (X)HTML, SMILE, SVG, etc. due to its dependency on RDFa.
