Squish - complex RDF queries in Java version 0.3 http://swordfish.rdfweb.org/rdfquery/ Squish is demonstration software written in Java for making complex queries of RDF on top of Java RDF APIs such as Jena[1] and the Stanford RDF API[2]. The SQL-like query language it uses is similar in some aspects to that used by R.V. Guha's rdfDB [3], and allows you to make complex queries of RDF models instead of navigating incrementally around them. Squish also uses the JDBC API to make RDF querying easier over RDF stored in SQL databases (Postgres) or in in-memory models. An alpha release and demonstration is available from http://swordfish.rdfweb.org/rdfquery/ The distribution includes the Java servlet runner Tomcat[4], and sample JSPs for querying RDF databases using JDBC, including a JSP which allows you to generate and display RSS 1.0 channels. This implementation is intended to demonstrate the possibilities of this approach, and is only appropriate for extremely small scale use. Comments are very welcome.
