My favorite new feature of the Normalizaiton Engine in 8.x version of AtriumCore is the Custom one.
I was very excited when I first saw that added because it allows for normalization of attribute fields. Some of the actions have a lot to offer when it comes to data enrichment, transformation and normalization.
You have functions like Concat, lower/UPPER, REPLACE, Substring, Truncate, Major (version). All of these can really help with automated data processing.
Anyone I've talked to about this feature raves about it . I personally use it every chance I get and it is a definetely one of the best new features of the AtriumCore. If you've not noticed it yet then please check out the Normalization Console - Normalization Features panel. I think you'll be amazed with this addition to the Normalization Engine.
