Fabric3 is an open source SCA runtime sponsored by Metaform Systems.
The goal of Fabric3 is to make developing and administering composite applications easier. The core Fabric3 design tenets are:
1. Runtime extensibility is central since application requirements vary.
2. Achieving feature depth is more important than breadth.
3. Completeness is not simply how many features software has; it is how well it works.
4. Third-party dependencies should be minimized since they contribute to complexity.
5. Simplicity is a sign of mature design.
