    Great talk, some interestings viewpoints.

    by William Martinez

    #, I would love to have more insight in actual apps using OSGi apart from the app servers and embedded things. What Neil mentioned, where are the banking apps, and some of the like?



    Now, just to clarify, SOA is more the architecture using the service metaphor. SOA is not a pattern, nor is it the web service triangle displayed. The service is modeled used the triangle, not SOA.



    Fascinating the concept of components as living things. In one of my university works I presented the notion of passive objects against dynamic or active objects. These second ones would have the same properties Neil adds to components, like awareness of environment and responsiveness to it. Still, components do not require that as minimum. A component can be a dumb thing, passive.



    And of course, components using services to offer functionality is one of the ideas under SCA.



    At the end of the day, this proposal is about an SOA infraestructure (OSGi) used to create an COA application. Interesting.

    Funny. His definition of Components is precisely the same definition DAI people use for Agents.
