EasyRdf

Designed to be used by experienced and inexperienced RDF developers it is written in Object Oriented PHP code.

During parsing EasyRdf builds up a graph of PHP objects that can then be walked around to get the data to be placed on the page.

Data is typically loaded into a EasyRdf_Graph object from source RDF documents.

The source document could either be an RDF file on the web or the output of a Construct or Describe SPARQL query from a triplestore.
