Instead of
e.g.http://lv2plug.in/ns/lv2core#ControlPort
you can just write lv2:ControlPort
That I understand. But:
1. The logic that allows this is hard coded in the LV2 host,
it is not the result of 'including' the @prefix. Checking
that the @prefix is present does not mean that whatever
is hard coded corresponds to what the @prefix is supposed
to imply. This is what I mean when saying that all this
just provides 'an illusion of conformity'.
@prefix is just turtle language. It's nearly the first you read about in
the introduction for RDF 1.1 Turtle
