SOFA 2 is a component system with many advanced features like hierarchical components, transparent distribution via software connectors or behavior verification.

New release brings a tags support which allows users to mark repository elements with user-defined tags. The tags can be further used in SOFA tools (cushion, SOFA IDE, MConsole) for referencing repository elements instead of specifying an exact version.

For more info about tags see http://sofa.ow2.org/.
