Just a stray thought from last week's call. There was much talk about
scalability.  It's important to be clear that there are two completely
different kinds of scalability for us to worry about.  We need database
scalability to deal with large numbers of triples.  Entirely separately,
we need ontology scalability that will let us deal with hundreds of
different ontologies in the system.  The issue of database scalability
is relatively well understood, I think, but the issue of ontology scalability
is a mysterious one.  Our recent demo showed a plausible story for how
to cope with scaling from one ontology to two, but I think we are going
to have to work a lot harder at the UI and system architecture if we
want to get all the way up to hundreds---ie, we can no longer due extensive
per-ontology software development.
