Presentation Summary: “MPTStore: Implementing a fast, scalable, and stable RDBMS-backed triplestore for Fedora and the NSDL”

Chris Wilper gave this presentation on behalf of the work that he and Aaron Birkland did to improve the performance of the Fedora Resource Index.

Version 2.0 of the Fedora digital object repository software added a feature called the Resource Index (RI). Based on Resource Description Framework (RDF) triples, the RI provided quick access to relationships between objects as well as to the descriptive elements of the object itself. After about two years of use using the Kowari software, the RI has pointed to a number of challenges for “triplestores”: scalability (few triplestores are designed for greater than 100 million triples); performance; and stability (frequent “rebuilds”).

“Cautiously Optimistic”

During the cookies and lemonade break during JCDL this afternoon I surprised one of the well-respected elders of the field with this question: are we really making progress? are we winning a fight against entropy 1? I wasn’t out for a quote for publication at the time so I won’t reveal the individual’s name, but I will report that there was a chuckle then the reply “cautiously optimistic.”
