Randall Hauch updated DNA-404:
------------------------------

        Summary: Remove ObservationService, migrate usage to observe RepositoryLibrary  (was: Change ObservationService to use the Graph event system rather than JCR)
    Description: 
The ObservationService is no longer needed since DNA-252 has added an observation framework to the graph API and RepositoryLibrary now manages the list of registered observers.  All components that use the Observation Service should be changed to use Observers registered via the RepositoryLibrary.

This will likely require changes to the Getting Started examples and documentation.

  was:
The ObservationService currently depends on a JCR implementation, but we want to remove the dependency on JCR from 'dna-repository'.  See DNA-401 and DNA-252.  Therefore, we need to change the ObservationService to utilize the Graph API's event system (DNA-252).

This will likely require changes to the Getting Started examples and documentation.

        Affects: [Documentation (Ref Guide, User Guide, etc.), Interactive Demo/Tutorial]  (was: [Interactive Demo/Tutorial, Documentation (Ref Guide, User Guide, etc.)])


Changed title to better reflect the actual change, now that DNA-252 has completed the new observation framework in the graph API. The ObservationService is no longer needed, so all components that use it should be changed to use Observers registered via the RepositoryLibrary.
