  triple-store)
• Graph-based index includes
• Object properties and Dublin Core
• Object Relationships
• Object Disseminations
• RI Search
• Powerful querying of graph of inter-related
  objects
• REST-based query interface (using RDQL or ITQL)
• Results in different formats (triples, tuples,
  sparql)
