ye olde HL7

Right now, I'm working on mapping HL7 v2.x (not V3) messaging to a Semantic
(OWL/Graph) equivalent (first documentation at http://hoot72.wordpress.com).
I don't want to reinvent the wheel, would like to bounce this thing off
others doing similar stuff. I've seen references to HL7 V3 (RIM) on this
group and on the HCLS pages but no v2.x. Is anyone on this group interested
in ye olde v2.x?

thx,
Conor
