-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear group members, most of currently available RDF triple store implementations (Jena, 3store, sesame, etc.) use relational database systems as the underlying information system. Well, I guess this is because they are well known, have proven to scale and perform, you get existing features for data management, indexing, transactions, etc. and can use existing tools. However, are there any resources (papers/projects/links/...) where RDF storage in network/hierarchical databases is investigated? Would there be benefits? The bottlenecks with RDBMS are either huge joins over the same table => memory problem for large datasets or complex query processing which at the moment has to be done in the higher app level. There should be better support inside the DBMS in future like special join operations. If sb has pointers or comments, I'd appreciate! best regards, Andy - -- - ---------------------------------------------------------------------- Dipl.-Ing.(FH) Andreas Langegger Institute for Applied Knowledge Processing Johannes Kepler University Linz A-4040 Linz, Altenberger Straße 69 > http://www.faw.at > http://www.langegger.at -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGLx+oKk9SuaNc5+IRAhuRAKDVaCd+Gur+rWZlRH6ZC2HbePBVCgCg2iJ5 eGHDozDvl7EauBy06TFnsZ8= =H1Ia -----END PGP SIGNATURE-----
