I have finally released the first WordPress plugin I have written as part of the LocaHero project. The plugin itself once installed adds a SIOC compliant RDF feed to a WordPress site.
The current RDF feed is deficient as it basically just rehashes the existing RSS feed as RDF XML. LH-RDF is an improvement as it exposes the internal post, author, and category objects as dereferencable URI thus publishing them in the semantic web.
Whilst this plugin is built on a standalone standalone it is built to work with and is enhanced by the LH-Relationships plugin. LH Relationships is a wordpress plugin that enables the creation of true semantic post to post relationships and when used in conjunction LH-RDF those triples will be published in the LH-RDF feed.
