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.
