the Apache UIMA team is pleased to announce the release of 

Apache UIMA Java SDK JSON CAS I/O v0.4.0.  

Apache UIMA <http://uima.apache.org> is a component architecture and framework
for the analysis of unstructured content like text, video and audio data.

The JSON CAS I/O implementation for use with the UIMA Java SDK allows to serialize UIMA CAS data to
JSON and to de-serialize the data back from JSON again, loading it into a CAS object. The aim of
this library is to facilitate the data interoperability of UIMA data across different platforms and 
programming languages. For example, the implementation contains functionality to deal with the 
different character offset counting strategies used by different languages such as Java and Python.
A Python-based implementation of the UIMA JSON CAS format is available as part of the third-party
DKPro Cassis [7] library.

This is the first public release based on the JSON serialization of the Apache UIMA CAS draft
specification version 0.4.0. Please note that the implementation and the specification are not yet
final. For this reason, is not yet recommended to use this library in scenarios where data needs to
be stored or archived over an extended period of time as future versions of the implementation and
specification may introduce incompatibilities with the current version. Good usage scenarios are
for example short-term data exchange between different UIMA implementations such as for example in
network communication.

A full list of issues [1] addressed in this release can be found on issue tracker.

Please use the mailing lists [2] for feedback and the issue tracker [2] to report bugs.
