The RDF CP is a very simple, read-only IdAS Context Provider that can retrieve an RDF document from a URI and expose it as a Higgins Context.

Details

  • Javadoc: Javadoc
  • Status: first code in Higgins B-1-1-M3
  • Language: Java
  • Packaging: OSGI bundle

  • no plan

Configuration

The RDF CP expects a single configuration setting in its ContextId via the Configuration API: uri

Example configuration using an XML configuration file: 

<Configuration
	xmlns:xsd="http://www.w3.org/2001/XMLSchema"
	xmlns="http://higgins.eclipse.org/Configuration"
	xmlns:htf="http://higgins.eclipse.org/Configuration">
	xsd:schemaLocation="http://higgins.eclipse.org/Configuration Configuration.xsd ">
 
	<!--  The setting handlers are classes that consume Setting elements where the Type matches and generate an object of the Class -->

Service

  • The RDF CP does not require authentication materials. It assumes that anyone can retrieve the URI with the RDF data.
  • The RDF CP sends an "Accept: application/rdf+xml" HTTP header when retrieving the RDF data.
  • The RDF CP is suitable for reading RDF data from and Hash Cool URIs.
  • The RDF CP is useful in conjunction with IdAS_UDI_Resolution, since 303 and Hash Cool URIs are one type of Entity UDI. However, the RDF CP does not depend on UDI.
  • The recommended Context Type for contexts opened with the RDF CP is $context$mime*application*rdf.xml.
