Richard Eckart de Castilho commented on UIMA-4685:
--------------------------------------------------

> In particular, is there a use case for Compressed Form 6 wanting to use TSI 
> info, for purposes of resetting the CAS type system, instead of using it to 
> specify just the TS and do lenient deserialization into the existing CAS?

One such case would be the desire of having a self-contained compressed/binary 
format that can be loaded into the CAS editor without having to specify the 
type system through a second file. Or said otherwise: why should one have to 
specify a TS file if the document file already contains a TS?

> Add Common Load/Save APIs, including type system and index defs, for various 
> CAS formats

>          Issue Type: New Feature
>          Components: CasEditor, Core Java Framework
>    Affects Versions: 2.8.1SDK
>            Reporter: Peter Klügl
>            Assignee: Peter Klügl
>             Fix For: 2.9.0SDK

>         Attachments: BinaryCasIOUtils.java, caseditor.csv, 
> caseditor_bincas.csv

> Create a new CasIOUtils class having common load and save APIs, with optional 
> saving of type system and index definitions, in all the various CAS 
> serialization formats (except JSON).  Implement heuristic discovery for 
> deserialization to support automatic selection of the right kind of 
> deserializer.  Update the headers for binary to support indicating they have 
> the type system included (not used yet).  Update the SerialFormat to support 
> this.  Update the CasEditor and other components to use this new API.
