Feel like I'm in college and missed a class lecture - what's the standard for JSON API descriptions and where can I learn more so that I can upgrade my APIs to have a usable JSON description?
Follow-up: Looks like JSON Schema is emerging as the standard, in part thanks to Swagger and Google adopting it for their APIs. References to Amazon and Heroku doing so as well (not exhaustive list, just what I've found while searching).
Not sure if there's really a _standard_, but there are examples of projects[1] and generators[2] that encourage best practices. Presumably if you can document your API as JSON, it should be reasonably well-formed.
