22 * Ontology of Nexus. This is still Maven2 specific. Ideally, Nexus Ontology should contain three things only: path,
23 * sha1 and last_modified. And Indexer should index _everything_, and Maven should be just "topping" extending these
24 * informations. This would enable us to search and easily detect maven metadata files too, or to support non-maven
25 * repository indexing, like P2 is.
