It looks like everyone working on dotLRN is really busy at the
moment (can't imagine why). 😉
The dotLRN website has
changed, but a couple of days ago there was a nice little
diagram that pointed out that dotLRN version 3 will be OKI
compliant (v.1=SloanSpace, v.2=OpenACS rewrite a.k.a
dotLRN).
I have not heard anything about DSpace or ICampus.
