Release Name: activerdf_jena 0.1

Notes: This is the ActiveRDF adapter to the Jena RDF library. Features: * supports memory, file and database stores; database stores can be configured both with datasources and raw connection parameters. Jena currently supports Oracle, MySQL, HSQLDB, PostgreSQL, MS SQL, and Derby. * supports reasoners, including Pellet and the built-in Jena reasoners * supports Lucene query support in ARQ (since LARQ doesn't allow you to add statements and reindex only those statements, whenever we've add a statement to a triple store, we must rebuild the index at query time) Requirements: * JRuby is required to natively execute Jena * the application can only use pure ruby gems License: included LGPL license (version 2 or later). ------------ Installing and running Activerdf with Jena: ============================= Download the newest JRuby binary distribution from http://jruby.codehaus.org/ Unpack it somewhere, e.g. /usr/local/jruby Then set your environement: export JRUBY_HOME=/usr/local/jruby export JAVA_HOM=/path/to/java/home export PATH=$JRUBY_HOME/bin:$PATH check if you now have the correct jruby commands in your path: which jruby -> /usr/local/jruby/bin/jruby which gem -> /usr/local/jruby/bin/gem Now you can install rails and activerdf: gem install rails --include-dependencies --no-rdoc --no-ri gem install activerdf --include-dependencies gem install activerdf_jena --include-dependencies Create an instance of the jena adapter with simple file based persistence, and load some data into it: this_dir = File.dirname(File.expand_path(__FILE__)) adapter = ConnectionPool.add_data_source(:type => :jena, :model => "superfunky", :file => this_dir + "/jena_persistence") adapter.load("file://" + this_dir + "/test_data.rdf", :format => :rdfxml, :into => :default_model ) For more information please see the RDoc, the adapter source code and the unit tests.
