Open Stack

I think we'd better to have a clear guidance here.

For projects that are currently using WSME, should they have a plan to migrate to other tools? If yes, is there any suggestion for the replacement tools? I think it will be more clear to have an official guideline in this matter.

Best regards,
Hongbin

One big reason for choosing WSME early on was that it had support for both XML and JSON APIs without the application code needing to do anything explicitly. In the time since projects started using WSME, the community has decided to stop providing XML API support and some other tools have been picked up (JSONSchema, Voluptuous,
etc.) that provide parsing and validation features similar to WSME.
It seems natural that we build new APIs using those tools instead of WSME. For existing functioning API endpoints, we can leave them alone (using WSME) or change them one at a time as they are extended with new features. I don't see any reason to rewrite anything just to change tools.
