• Constrained set of APIs encourage a RESTful application
architecture
• Data model that maps well into Atom feeds and JSON
formats
• Robust framework for persistence, validation, and
Access resource data with Dojo serialization
24. Light-weight Flow in WebSphere sMash
• Assemble Flow is target to compose application with the
flow pattern by “wiring” activities.

• <receiveGET name="rssRcv"/> model and engine
Light-weight flow
