Adrian Sutton - Atom Is The New JCR:
"When the Java Content Repository (JCR) standard first came out it was supposed to bring in a new era of compatibility between content repositories and put an end to the content silo. There was, and still is, a lot of talk about it and just about everyone added JCR compliance to their marketing materials. [...] There are a few CMSs around that do have good JCR support - Alfresco for example - but they're few and far between and even with that, there isn't a lot of people taking advantage of that support and the standardization of the repository interface.
Then along came Atom which is all about remote access and manipulation of data and missing probably 90% of the functionality that JCR offers. It really isn't a competitor to JCR at all and yet it's doing more to break down content silos than JCR ever has.
[...] Having Atom support in your product, serving and consuming as necessary is becoming an extremely powerful feature."
