Hi Danny, Toni-- (02)
I think you're talking about different things. Danny is talking about
users placing nodes explicitly on the screen, arranging them into
spatial structures (as in Ideagraph). Toni is talking about automatic
views as in Fenfire Loom (or Gzz/GZigZag), where the program
automatically arranges nodes on the screen to convey the underlying RDF
structure (or zzstructure). (03)
Indeed, in our Loom views, we regularly show the same node multiple
times: say that "noteA seeAlso noteB" and "noteB isReasonFor noteA" for
example; then, when we focus noteA, noteB is related to it in two ways,
and we show it twice because of that. (Sorry, I don't have a screenshot
program ready :-/ ) (04)
After reflection, I do think that placing the same node at two different
locations can make sense, though. In Spatial Hypertext, the arrangement
of nodes is used to convey structure as we would on e.g. a conventional
blackboard or scratchpad etc. (05)
Let's say a user is making groups of people by placing person nodes
together in different locations of the screen (spatial canvas). What if
a person is in more than one group? (06)
(Maybe these kinds of spatial structuring isn't what you're after in
Ideagraph; but on the other hand, why allow the user to hand-structure
the arrangement of the graph if not to have them make use of that
spatial arrangement? In any case, it would be nice if the same
vocabulary could be used by other tools that let users arrange things
spatially...) (07)
