  * Ontology of Nexus. This is still Maven2 specific. Ideally, Nexus Ontology should contain three things only: path,

  * sha1 and last_modified. And Indexer should index _everything_, and Maven should be just "topping" extending these

  * informations. This would enable us to search and easily detect maven metadata files too, or to support non-maven

  * repository indexing, like P2 is.
