GMS uses dname : description name, or 'human readable name',
and name : an id number. Every instance of gms gets a id number too, so the
'Loci URI' is equalavent to gms's 'instance id + name', a 64bit number.

This is something gms wont touch, class 'types' wont exsist in this layer. They will
simply be handled as a node and passed to overflow.

Seems logical. There's no need to store x\y into the processing layer. But it wont
harm the GUI too, it can just ignore those values. Or is there a special reason to
have them inside the nodes?

OK, the overflow & loci people should define this definition. GMS will only use a few

lines where the gui and overflow layer will use every single line. Make it whatever
see fits best.
