Hi All,

following on from many previous emails; here's something to ponder:

- multiple "quads" or named graphs in a single rdf graph
- an asserted named graph
- a quoted named graph
- never describing a subject directly

hopefully should allow a groundwork for provenance, trust, and many
other things I'm sure you are all aware of. Looks quite interesting when
you generate a visual graph of the data model too (using say w3c rdf
validator)

simply putting this forward to the group for feedback and thoughts:
