Description/Abstract

This report considers the requirement for fast, efficient, and scalable triple stores as part of the effort to enable the Semantic Web. It summarises relevant information in the background field of Database Management Systems (DBMS), and analyses these techniques for the purposes of application in the field of RDF storage. The report concludes that for individuals and organisations to be willing to use Semantic Web technologies, data stores must advance beyond their current state. The report notes that there are several areas with opportunities for development, including scalability, low latency querying, distributed and federated stores, and improved support for updates and deletions. Experiences from the DBMS field can be used to maximise RDF store performance, and suggestions are provided for lines of investigation. Work already performed by the author on benchmarking and distributed storage is described, and a proposal made to research low-latency RDF querying for the purpose of supporting applications that require human interaction. Work packages are provided describing expected timetables for the remainder of the PhD program.
