What defines a permitted key ?

[JulienPalard]

I have a key named "URL" in a document, which looks good to me (an accronym should be all-caps, for me) but prmd verify whines about:

schema.json: #/definitions/video/properties: failed schema #/definitions/resource/properties/properties: "URL" is not a permitted key.

Why is that ? Is there a spec I missed telling allcaps properties are not permitted ? I did not see it while re-reading spec of json-schema and json hyper schema.

I also did not find where it is implemented in your code, so I can't tell why you did it that way, can you enlighten me please ?

Found it, here:

prmd/schemas/interagent-hyper-schema.json

Line 69 in 9414e9c

"^[a-z][a-zA-Z_]*[a-zA-Z]$": {

Where does this come from ? I don't see it in http://json-schema.org/hyper-schema

Good question. That definitely looks like where the error is coming from, but I'm afraid I don't remember why (and maybe it was an accident or is incidental).

@brandur it looks like the interagent hyperschema allows caps in properties, but enforces that the first letter be lowercase. Do you remember how/why that might be? Thanks!
