Schema Mapping Validation Between JSON Schemas

[luiz00martins]

What version of Ajv are you using?

8.11.2

What problem do you want to solve?

I need to validate one JSON schema against another to ensure they map onto each other based on their description. I'll be using one schema for output of a process and another for input into another process in my system, which would necessitate a validation check to ensure they align correctly.

Note: I considered the idea of doing it dynamically (i.e. checking against the actual output of the process, instead of the schemas). However, I need to detect a possible mismatch before any processing happens.

What do you think is the correct solution to the problem?

Implementing a Schema Mapping Validation feature between JSON schemas could do it. For instance:

1. A string schema A maps onto a string schema B if it meets the length and pattern requirements of B.
2. An object schema A fits onto object schema B if it encompasses at least the same required properties as B.
3. A null schema A maps onto any schema B if B also includes null as an allowable type.

Will you be able to implement it?

I might be able to implement it, although I am unsure about the complexity within the library's framework. However, I am certainly willing to give it a shot!
