If you havn't read up on the blocks docs on the wiki lately (the last two weeks) you really should. Stefano has put a good series of pages up detailing the plan and the current implementation ideas.


Another followup question related to the following note on the wiki:

   * dependencies:
         o the URI(s) of the blocks on which this blocks depends on
           (optional)

I'm thinking about this relative to Avalon Merlin Block dependencies. Under Merlin a block dependency is implicit - not explicit. By implicit I mean that you can establish the dependencies that a blocks has relative to the computational dependencies that the blocks implementation exposes. This means that a deployment system (tool or container) can resolve dependencies at runtime, using (a) locally available resources, (b) external repositories, or via more complex means (roadmap stuff) using (c) a remotely accessible service provider, or (d) remotely provided serialized block descriptions.

What I have not resolved in my head yet is how the dependency url for cocoon blocks translate to computational descriptions (or to put this into Merlin terms, how can I translate a cocoon block uri into computation service request that could be used in Merlin to return a serialized Merlin block descriptor)?

Stephen.
