python3-jdata 0.3.6-1build1 (amd64 binary) in ubuntu lunar

 The JData Specification (https://github.com/fangq/jdata/) defines a
 lightweight language-independent data annotation interface targeted at
 storing and sharing complex data structures across different programming
 languages such as MATLAB, JavaScript, python etc. Using JData formats, a
 complex python data structure can be encoded as a `dict` object that is
 easily serialized as a JSON/binary JSON file and share such data between
 programs of different languages.
