Drupal is one of the world’s most popular open source content management systems. It already has good tradition of being an early adopter of Semantic Web technologies, such as RDFa which has been added to Drupal core with the release of Drupal 7 in January 2011; or the SPARQL Views module – a graphical tool for querying and displaying data fetched from SPARQL endpoints. Also, there have been already Drupal related IKS early adopter projects which have successfully shown how powerful the combination of Drupal and semantic technologies can be, e.g. test this demo of the Aloha Editor, Apache Stanbol and Drupal 7.
We continue this good relationship with our early adopter project by creating a tighter integration between Drupal and Apache Stanbol, a Java based tool that provides a set of reusable components for semantic content management. We leverage Apache Stanbol's RESTful web service to directly send Drupal’s content over to Apache Stanbol for indexing, possibly including all of Drupal entities and fields. Once Drupal’s structured data is indexed by Stanbol, it will become available to the rest of the IKS software stack to perform content enhancement tasks such as finding related content, suggesting relations as content is being authored, and improved search.
