It is desirable to be able to *see* from the URI which data is
stable, which is not, without having to look at the definitions.

For example, grepping for the experimental ns from a file would
give you a good idea whether your data is based on stable code.

The idea is also that conversion wouldn't be too often necessary:
the move from lava to real wouldn't require too much work, just a PEG
round.

Yes, it's more important to remind humans, who can't know without
referring to the vocabs unless it's in the name.

How about "rdfv"? Or something..

I don't like "terms" you use below, since it refers equally well to human
words - at least rdf is stuff about RDF, not a glossary.

Agreed.

You're right, that's better.
