             Summary: eliminate need for shared data parameter in xmi serialization
                 Key: UIMA-4991
                 URL: https://issues.apache.org/jira/browse/UIMA-4991
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
    Affects Versions: 2.8.1SDK
            Reporter: Marshall Schor
            Assignee: Marshall Schor
            Priority: Minor
             Fix For: 3.0.0SDKexp, 2.8.2SDK


The recent problem ( UIMA-4990 ) was caused by an improper use of a mostly undocumented parameter in the XMI serialization API - the XmiSerializationSharedData parameter.  This is used for handling out-of-type-system data when sending a CAS to a remote service, and for merging multiple CASes being returned from multiple remote services.  

It is easy to misuse, and can result in strange errors (e.g. UIMA-4990 ).  

This improvement would move this to be an internal capability, no longer exposed in the API (existing API uses with it would be deprecated; instances of this, if passed in, would be ignored in favor of internal memory for this).

This would enable automatic management of this data. There is a similar concept in the experimental Uima V3 prototype and an extra CAS Api for eliminating the extra storage if sophisticated users know early on it won't be needed.
