Most worrying is that there is a lack of standalone implementations, that is vendors that specialize in Audit Record Repository functionality. I know these exist, but they don't show up on the search.
It is very important for the success of the IHE process that vendors publish their "IHE Integration Statement" on the internet. This is not just true for ATNA, but for all Profiles.
I expect that my blog followers are the likely audience to be these Implementations, or at least those that know some. So I ask that if you have an implementation of the IHE ATNA Audit Record Repository, please post a comment on this article that points at your IHE Integration Statement for that product. I am fine with you explaining your implementation capabilities in a few sentences, but please don't make me regret this offer.
If you know of an ATNA Audit Record Repository and don't see it show up, please let me know. Or better, let THEM know.
