[topicmapmail] Logical File System - A model for a Topic Map UI?

[Thomas B. Passin]

This very intriguing work was just referenced on xml-dev. It discribes a
file system that is actually working today that used path expressions to
access files, and presents files in a virtual hierarchical view (just like
regular file systems).  But the views are constructed using logical queries
based on file attributes, and the steps in the paths are all virtual, made
up of keywords or temporary names you give to previous queries.

IOW, they have made a relational file database navigable as if it were an
ordinary system, but more effectively.  cd, ls, glob, etc all work on these
virtual paths.  They use a prolog engine, which does some inferencing, and
supposedly test resulst show little effect of query processing overhead.
