GoodRelations Shop Extension for Joomla / VirtueMart
... an extension for VirtueMart, the popular Joomla shopping cart solution, which creates GoodRelations feeds (GoodRelations e-commerce vocabulary) of product offerings and thereby adds additional visibility and ties to your product sites by introducing Semantic Web capability (aka Web of Linked Data).
I just released a second version for this extension in July 2010. The project Web site is located at http://code.google.com/p/goodrelations-for-joomla/.
The latest code commit stems from July 28, 2010.
The GoodRelations ontology is currently supported by the Semantic Web search-engine Yahoo SearchMonkey.
