13. Apache Aries – Project Overview BarCampRDUOctober 23, 201013 Future Ideas / Work in Progress There are many new application-centric features that Aries may develop including: application isolation message-driven blueprint components and services declarative role-based security for blueprint components annotation-based alternative to XML configuration resource-reference metadata and bindings Interested in giving it a go? http://incubator.apache.org/aries/ Interested in getting involved? http://incubator.apache.org/aries/gettinginvolved.html
