3. CTS2 JSON Background/History CTS2 representation (at a PSM) level is XML. With XSDs, we can specify exact structure, and have a mechanism for validating correctness. XSDs are expressive enough to allow for the model constraints.

4. CTS2 JSON Background/History Clients demand JSON. Implementers will most likely expose some sort of JSON representation of CTS2. Currently, no standard representation of CTS2 in JSON. JSON may not be interoperable, as slight differences in JSON renderings are common among different libraries. There is no JSON validation.

5. CTS2 JSON Background/History At the June 2013 Berlin OMG meeting, we discussed this issue with Andrew Watson and Tom Rutt. We decided to make CTS2 specific rules for transforming XML to JSON. These rules will be captured in this RFC. Implementers can then follow these rules to modify or create JSON libraries or transformation tools.

8. Proposed Process Parallel or Linear? JSON RFC and CTS2 RTF 1.2 running in parallel. Expect the JSON RFC FTF to be complete in time to be included into the CTS2 RTF 1.2. There will be a final report for both the RFC FTF and CTS2 RTF 1.2. Include a combined convenience document with changes from both RFC FTF and CTS2 RTF 1.2.
