Implement Semantic Service Execution atop OSGi framework

Reported by: ben Assigned to: mroy
Priority: major Milestone: 3.0 milestone2
Component: openanzo Version: 3.0
Keywords: Cc:

Description

- SemanticExecutionService/SemanticServiceActivator?

  • register a tracker for ISemanticServiceExecutor

  • register the service with the bundle context

  • maintain a mapping from serviceTypeUri to executor

  • retrieve serviceTypeUri from the executor

  • maintain a mapping from serviceUri to serviceTypeUri/executor

  • when our executor tracker fires, we set ourselves on the executor as the host it the executor will tell us of its services so far.

  • get the serviceTypeUri from the executor instance

  • find all services of that type in the registry

  • check(*), via abstract method, if the service is ready to execute (the Java bundle might not be ready for example)

  • if it isn't do nothing

  • if it is, then we create a ServiceInfo? object in the table, keyed by serviceUri, pointing to the executor

  • register a listener on the registery for new services of the proper type

  • perform same check(*) as above.

  • whenever a new services is available, we register it via its type and uri with the host (semantic service execution service)

  • maintian a mapping from PID to implementation factory

  • register a tracker for ISemanticServiceFactory instances.

  • when one arrives, check the registry for a java service with the right PID

  • if we have to create the service, instantiate it with the config graph from the registry, and store it in a map from serviceUri to ISemanticService

  • base class for all java service bundle activators.
