At the time that Steven, Philip and I had our conversation, I committed =
to do the work and to come up with a proposal. For quite some time I had =
no time to work on this, but actually, an analysis the design of several =
UIMA type systems has meanwhile been done. As this is part of ongoing =
research, I cannot share this with the general public right now, but =
will be more than happy to do it as soon as I can. I'll also still be =
happy to take the lead (or at least one of the leads) on the proposal. =
As for a time frame, I think getting an initial suggestion ready around =
Q1 2014 is realistic.=20

In my opinion, ClearTK, cTAKES and DKPro Core all bring in distinct =
design choices that should be combinable with each other for an =
extensible base type system. I'd personally not suggest to take any of =
the type systems as is (without modifications) as the basis for a =
proposal.
