The Ontopia product only accepts modules which are developed, tested, and documented to a commercial standard, which makes the bar for new submissions rather high. In order to make it easier for the community to share useful modules we have established the Ontopia Forge, which contains all kinds of modules related to Ontopia contributed by the community. Currently the following modules are available:

• An implementation of the Toma query language
• tmphoto, a web photo gallery based on Ontopia
• tmcl-owl, converters between RDFS/OWL and TMCL
• An Ontopia/Liferay integration
• A faceted search implementation using Apache Solr
• A TMCL reference implementation
• The TMQL4J engine (plugs into the Omnigator query plug-in)
• An SDshare implementation (see blog post)

If you want to contribute a module of your own, to be hosted in the Ontopia Subversion repository or externally, please contact us.
