A new release of TriplifyPlugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data. (http://dl-learner.org/Projects/Triplify), a web app plugin that converts queries to relational databases into RDF, JSON and Linked Data, was announced yesterday. According to AKSW’s blog (Agile Knowledge Engineering and Semantic Web research group at Leipzig University), it comprises the following updates:

• update log functionality* added – allows Semantic Web crawlers to get incremental updates, see http://triplify.org/vocabulary/update
• linked data publication now also works without Apache’s mod_rewrite
• Syntax for indicating objectProperties added, e.g.:SELECT id,user_id 'sioc:has_creator->user'
• Additional metadata can now be added via $triplify[’metadata’]
• The configuration variable $triplify[’CallbackFunctions’] allows programmatic post processing of DB content
