Neologism Web-based RDFS vocabulary editor

Neologism is a simple web-based RDF Schema vocabulary editor and publishing system under development at DERI. It looks like a great lightweight tool for developing Semantic Web vocabularies and publishing them on the Web following current best practices. It's goal is to "dramatically reduce the time required to create, publish and modify vocabularies for the Semantic Web." The system is not yet open for use, but there is a good online Neologism demo as well as a screencast of how to use it.
