RE: New BNB sample data available

Simon,

 

We appear to be using the term "extension" in different ways. I assumed
you meant it in the OWL sense:

 

"Classes provide an abstraction mechanism for grouping resources with
similar characteristics. Like RDF classes, every OWL class is associated
with a set of individuals, called the class extension."

http://www.w3.org/TR/owl-ref/#Class

 

Do you have a reference I could check out for how the term is used
differently in KOS systems to indicate a set of documents instead?

	I'm confused by your statement "the Concepts have the same
extension".

 

The extension of a KOS Concept is the set of all documents that the
Concept is about.
