•
0 recomendaciones•1,682 vistas
MPTStore is a resource index for Fedora that uses a relational database to store RDF triples in a fast, scalable, and stable way. It maps predicates to tables to improve performance of queries and updates. Tests showed MPTStore had significantly faster datastream modifications than the existing Kowari triplestore and comparable query speeds. Its use of a relational database provided benefits like transaction support and ease of administration compared to other triplestores.
