This is where new visualization tech may help.
Any attempt to define some name by a set of numbers
and letters is just an attempt to position it in some graph
with respect to others which may have some relationships.
When you can easily manipulate some familiar map
leading from the general to the specific, or vv,
then all you need to remember is how to access the map.

This is part of the idea of having the DKR provide a map
of its contents. The OHS would be able to access various
representations of this map and even derive a map of its
own. I still think of this as a node map because each subdivision
of content is a node, but the concept of topics also fits.

I am encouraged with this thought by association with the group that among other things is implementing
XML encoding of VRML. Along with this is integration of
w3c DOM interfaces. Naturally, the topics of heirarchy and
inheritance arise. This is allowing me to see the
opportunity to treat tremendously complex collections
of information as a node in a graph, that consists of other
nodes, some of which may be on other graphs, which may be
part of other graphs, all of which may be part of or referenced
by other nodes and graphs,
with navigational interfaces clearly defined.
That is, the node can consist of nodes and graphs and
may be a part of a node on a graph,
and they can all talk to each other.

Thank You and Best Regards,
