Hi Andy,


I thought about the jena list, but since someone recently posted inquiring about a command-line tools for inferring, I'm hoping this is relevant to other subscribers.


Your response doesn't my question just yet.  I know what RDFS is, :-), but I don't know what are valid values for VOCAB,


E.g.,


C:\Programs\apache-jena-3.1.0>infer

What values can I put in for VOCAB?

Probably better on the users@jena.apache.org mailing list.

The RDFS schema - subclass, subproperty range and domain declarations.

It is applied to FILEs to produce a stream of output of ground and
inferred data.
