Title / Titel The Scalable Triple Store
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung The vision of the Semantic Web is to allow everybody to publish interlinked machine-processable information with the ease of publishing a web page. The basis for this vision is a standardized language for publishing these information called Resource Description Format (RDF) that uses typed graphs as its major abstraction. A number of toolkits for processing and storing RDF-based data exist. They are typically called triple stores, due to the 3-tuple (or triple) based nature of the building blocks of a typed graph, each triple storing one of the RDF elements (Subject, Predicate, Object). Most existing triple stores, however, scale rather poorly.

With the rapid growth of RDF based data on the Internet, it is becoming increasingly more challenging to query semantic data sources. Current solutions include crawling of Linked Open Data (LOD) or federated query (SPARQL) processing. Scalable methods to retrieve and process such information stil remain open problems to date.
