Richard Eckart de Castilho resolved UIMA-1970.
----------------------------------------------
    Resolution: Unresolved

Looks like this never cought on. I'd am resolving this issue as "unresolved".

If resources need to auto-update, then IMHO the resource implementation should take care of this, not the UIMA framework.

Feel free to re-open if this is still considered to be important.

>                 Key: UIMA-1970
>                 URL: https://issues.apache.org/jira/browse/UIMA-1970
>             Project: UIMA
>          Issue Type: New Feature
>          Components: Core Java Framework
>    Affects Versions: 2.3.1SDK
>            Reporter: Joern Kottmann
>              Labels: Resources
>
> In many use cases resources used by Analysis Engine are updated more frequently than the AE implementation.
> Samples of such resources are huge dictionaries which are extended with new names on a daily basis
> or statistical models which are re-trained frequently to be adjusted to data from the past minutes.  
> For a resource updates an analysis pipeline has to be stopped and started manually to pick up the updated resource.
> It would be nice if the framework could automate this procedure. In order to do that it must have a capability to detect
> updated resources and perform the re-initialization of affected Analysis Engines.
> If the pipelines run multiple instances of these Analysis Engines it would be nice if a rolling
> update could be performed in a way that the processing of CASes never comes to an halt.
> That should be handled in different issues for the CPE and UIMA-AS.
