Boy, does that sound interesting.
Had to check, yup, you own VDCG.
"a node has a different set of children in each graph."
That's the crux of what interests me, which I see as spatial
versus temporal versioning.
"here is the content of this node, next to it is this other thing,
above it is yet another ..."
as apposed to
"here is the content of this node, previously it was this thing,
in the future it will be yet another thing."
To specify a graph, a key for that graph must be known,
I just call the keys 'coordinates'
At least in my little mind the spatial model makes more sense.
Good luck with it.
Thanks,
Kent
