------------------------------------

             Summary: UIMA CasIOUtils enhancements in handling type systems
                 Key: UIMA-5135
                 URL: https://issues.apache.org/jira/browse/UIMA-5135
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
            Reporter: Marshall Schor
            Priority: Minor
             Fix For: 3.0.0SDKexp, 2.9.1SDK


A recent Jira UIMA-5120 was logging CASs to file system directories, and including a type
system.  

It would be good to have a conventional,supported way to do this common kind of operation,
added to CasIOUtils.

Additionally, it would be good to support as an alternative the standard XML serialization
format for type systems.

Some possible conventions:  
* multiple cas files, in 1 directory, with one additional file with the name "typesystem.xml".
* the above style, in one zip file (for example, to be able to read it, one cas at a time,
via some iterator).
* finding a type system via the class path following uimaFIT conventions

It would be possible of course to support multiple conventions.  However, the more conventions,
the less benefit from "standardization", so this ought to be a balance.
