This document also defines the functional-style syntax, which closely follows the structural specification and allows OWL 2 ontologies to be written in a compact form. </p> <p><a href="http://billbreitmayer.com/drupal/node/89">read more</a></p> RDF-OWL Semantic Web Technology Fri, 31 Oct 2008 20:39:08 -0600 billb 89 at http://billbreitmayer.com/drupal Links - SWRL, OWL and the Inferencing Web http://billbreitmayer.com/drupal/node/190 <p>This is a new topic ... it is more abstract than most content on this site and may be moved to the Home site.</p> Inference Engines RDF-OWL Semantic Web Technology Fri, 03 Oct 2008 14:05:33 -0600 billb 190 at http://billbreitmayer.com/drupal Link - RDF API for PHP ( RAP ) http://billbreitmayer.com/drupal/node/124 <p><em>Updated Sept 24 2008: added features and SWCL link</em></p> <p><a href="http://billbreitmayer.com/drupal/node/124">read more</a></p> Inference Engine Projects PHP RDF-OWL Semantic Web Technology Sat, 20 Sep 2008 17:26:37 -0600 billb 124 at http://billbreitmayer.com/drupal Links - OWL/RDF Inferencing http://billbreitmayer.com/drupal/node/178 <p>More pattern matching and structural parsing than symbolic processing in a classical sense of an inference engine. </p> Inference Engines RDF-OWL Mon, 28 Jul 2008 13:54:39 -0600 billb 178 at http://billbreitmayer.com/drupal Links- Java RDF/OWL Tools http://billbreitmayer.com/drupal/node/174 <p>Of the <a href="http://www.mkbergman.com/?page_id=325">702 Semantic Web tools listed in Mike Bergman&#39;s masterlist</a>, 332 are implmented in Java .... and Java now being a fully open source and open licence language ... </p> <p>Stray link I&#39;ll find a home for: http://www.daml.org/tools/</p> <p>&nbsp;</p> <p><a href="http://sites.wiwiss.fu-berlin.de/suhl/bizer/ng4j/semwebclient/">SWCL - Semantic Web Client Library</a>:</p> <p><a href="http://billbreitmayer.com/drupal/node/174">read more</a></p> Java RDF-OWL Semantic Web Technology Thu, 10 Jul 2008 20:55:22 -0600 billb 174 at http://billbreitmayer.com/drupal Links - Drupal and RDF http://billbreitmayer.com/drupal/node/145 <p>Potential RDF use cases for Drupal - an excellent article about RDF in Drupal 6 - 7.</p> <p>The Drupal RDF module uses the recently-rewritten <a href="http://arc.semsol.org/">ARC2 RDF Library</a> if available but apparently does not require it.</p> <p>&nbsp;</p> Drupal RDF-OWL Fri, 21 Mar 2008 15:58:03 -0600 billb 145 at http://billbreitmayer.com/drupal Link - SemWeb Tools for PHP http://billbreitmayer.com/drupal/node/122 <p><em>Update 3/26/2008 - ARC completely reimplemented and released as ARC2.</em></p> <p><em>Update 7/25/2008 - added Triplify 0.3 section.</em> </p> <p>From the ARC site:</p> <blockquote><p>ARC is a lightweight, <a href="http://www.w3.org/TR/rdf-sparql-query/">SPARQL</a>-enabled <a href="http://www.w3.org/RDF/">RDF</a> system for mainstream Web projects.
