Don, OpenACS isn't, but AIESEC.net definitely is Oracle-only, right?
From reading it, Dirk's title on that working paper, "... specifically
in AIESEC.NET", is accurate but the description he gave when linking
to it above, "OpenACS Search proposal", definitely is not. It is only
about AIESEC's website, and is very brief even on that; it doesn't
really touch on the bigger OpenACS-in-general picture at all.
Dirk, it would be quite useful if you could extend that paper into a
"Site-Wide Search in AIESEC.NET, and in OpenACS in general" proposal,
with compare and contrast between AIESEC and OpenACS, practical
lessons learned from AIESEC and/or other live sites, etc.
