I think we miscommunicated. I didn't mean the unstructured wide-ranging
textual search of Google, but rather a structured lookup like DNS or
LDAP. Something I can use to build a roster of forum members, or
directory of document/filenames, or diary of dated journal entries or
list of billable timesheet entries extractable by non-prearranged (i.e.
written originally in monthly journals) date range.
Xanadu was to encompass all information storage, not just word
processing. In some manner it is to subsume SQL databases, LDAP rosters
and spreadsheets, among others. Admittedly much of that functionality
is to be located in the front-end, but the back-end must contain
sufficient architectural features to let you build those things, in a
The concepts of text + links is very powerful, but if you combine text +
links + lookups, you get all of the applications I listed above.
Structured link queries, which Xanadu has, just barely miss the goal of
lookups, because of the inability to supply external content as the
variable in the search.
