@mringer I have around 20 schemata, most of them are independent. A few reference one of the other schemata.

All of them must be “spoon-fed” upfront to ajv, first all $ref-ed ones, then all the other ones. Without the trick above, I get a lot of runtime errors about schema A not being known when $ref-ed from Schema B etc.

I do agree with you that all draft JSON schemata (v4, v5, v6, v7 and soon v8) MUST be registered with ajv - you refer to it as bootstrapping. That is the responsibility of angular2-json-schema-form.

fair enough, thanks for the heads up.
