I'm pleased to announce RDF-Source related Storage System (RDF-S3) version 1.1 beta! Open Source - Freeware - Java The RDF-Source related Storage System (RDF-S3) is a Java application for storing RDF statements into SQL databases using a schema specific storage approach. Each RDF statement keeps its relationship where it came from, more specific the system keeps the URI of the RDF file used to enter the statement into the system for each statement. The main motivation for it is the fact that also in real life we do not trust everything unless we know that the source is trustable. But there can be also other systems benefit from the source relational knowledge. Suppose you find a contradiction, you have the possibility to figure out the sources that are responsible for it, which makes it more easy to solve it and last but not least, if you have RDF embedded into HTML you might want to see the human readable HTML presentation of the statements. Without the source relation you are forced to start a new search. Features · stores the relationship of the RDF statements to their source · supports validation options by using VRP · only need JDBC-compliant RDBMS (supporting standard SQL) · automatic inclusion of missing (rdfs:Class & rdf:Property) type information · easy to use GUI (from the look and feel similar to RSSDB) · user friendly by using stored preferences Download RDF-S3 can be downloaded at: http://www.dbis.informatik.uni-frankfurt.de/~tolle/RDF/RDFS3/index.html RDF-S3 was developed by: Institute of Computer Science - Databases and Information Systems GERMANY and INSTITUTE OF COMPUTER SCIENCE Foundation of Research and Technology - Hellas GREECE Note: It is still a beta version and we expect frequently changes and will try to improve performance and scalability as well as defining access paths to the data after storage. Recommendations and comments are welcome! Best greetings, Karsten Tolle ___________________________________ Karsten TolleReceived on Tuesday, 18 November 2003 05:02:08 UTC
