[Semantic Web]Jena vs. Sesame

读书笔记,  科学研究 Lee 发表于 2006/2/23 23:27:22   Sesame  is a repository and querying facility based on RDF and RDF Schema. It features a generic architecture that separates the actual storage of RDF, functional modules offering operation on this RDF, and communication with these functional modules from outside the system. Sesame supports RDF/RDF Schema inference, but is an incomplete reasoner for OWL Lite. It can evaluate queries in SeRQL, RQL and RDQL. We evaluate two implementations of Sesame, main memory-based and database-based.   Jena , a Java framework for building Semantic Web applications. Jena currently supports both RDF/RDFS and OWL. Compared to Sesame, the most similar system to Jena here, Jena with RDFS reasoning was much slower in answering nearly all the queries. Some of the queries did not terminate even after being allowed to run for several hours. The situation was similar when Jena’s OWL reasoning was turned on.                             ---- from An Evaluation of Knowledge Base Systems for Large OWL Datasets
