In the last few years JSON came out as new format for data objects consisting of attribute-value pairs, largely replacing XML.
LabVIEW has functions to handle JSON data, and LabVIEW Community has been developing a JSON Toolkit.
In the CVI board of the forum this is the only result for a "JSON" search (at the present).
I suggest to integrate into CVI a JSON library (for example JANNSON).
I think this is better than develop a proprietary library.
