I'm about to start work on an(other) rdf browser. The idea is to
present rdf data in a 'coarse grained' way - eg vcard data as a box
containing name, tel no, photo etc.

The tricky bit will be the coarse graining. I'm considering
auto-generating classes which will pick out sub-graphs of an
underlying rdf model.

The question is - how? It seems like the best thing to use would be an
rdf query to a) express what subgraphs the class 'wraps' and maybe b)
represent the fields of the class.

eg for rdfDB [1] style queries the 'WHERE' clause corresponds to a)
and the SELECT clause (maybe) gives b).

I'm a lazy guy, so is anyone else doing something similar, or know of
similar projects? I've been looking at neoom [2] (thanks keo) and MDL
[3] (thanks danbri).

The problem of wrapping seems to crop up quite alot in rdf apps so any
work would help poor hackers. It also seems to relate to data
validation (eg Schemarama [4]).
