Hi Ian: Thanks for providing this service! Unfortunately, however, schemapedia.com does not find entries that contain the search term in their rdfs:label property. Do you think you can fix that? Also, it is kind of problematic that there are no hints regarding the tool support and popularity of a vocabulary. The likelihood of broad adoption is a critical factor for choosing an ontology due to the strong positive network externalities.
