Hope you are doing good.
I've been working on SOA & BPM for quite a long, I think its time to learn AIA as well.
I don't have any previous knowledge on AIA, really confused on Foundation Packs, PIPs, the nomenclature is a bit confusing.
Would you please recommend any good articles/book on AIA that will be the best kick-off for a beginner.
You can use the following document to Understand the AIA:

Hope this helps you..
