PERSEUS RDF Binding

This page is under construction and requires cleaning

Each PService can be set up to use several data sources - configurations. Annotations each PService provides can either be used as is, in the form of RDF, or can be interpreted. Interpretation is provided by visualizers and syndicators. Both visualizers and syndicators do the same work, but at a different level of granularity. Visualizers only interpret a piece of annotation PService associates with resource or a feed. Syndicators in addition encapsulate access to the resource feed(s) in the form of user interface.
