Anyone working on the IATA AIDM (Prolaborate repository)?

[Richard Freggi]

Hello my company is investigating the IATA IADM airline reference data model.  We are members of the group and have just started looking at it; the model is a Sparx EA in a prolaborate repository and the instructions to access it are clear, except the link needed to obtain a user ID points to the wrong page.  So we have not been able to access it yet (emails sent to IATA).
I would be interested to know if any of us has experuence with this model, what value we can expect to derive from it, and any tips or recommendations on how to best leverage it!  Thank you,
