 Description   

MongoDB currently only supports the Draft-04 JSON Schema standard (with some omissions) for validation purposes. Draft-04 is pretty long in the tooth now.

Please enhance JSON Schema validation to support the latest 2019-09 Draft of the standard, specifically including the ability to do conditional subschema validation (ie. if/then/else  keyword support), which can be found here: https://json-schema.org/specification.html

Mongoose provides good support for discriminators, where the structure of a document/subdocument depends on a type field (typically _type), as does Mongoid for subclasses.

Validation of collections that use discriminators is not really possible without support for the if/then/else JSON Schema specification laid out  in the most recent draft of the standard.

ataramina@shorecg.com understood. Our team will triage this feature request and decide on its priority.

Comment by Andrzej Taramina [ 28/May/20 ]

That is true....the if/then/else was just one of the major examples of what the latest JSON Schema draft standard provides.

Would also like to see support for unevaluatedProperties and any other features that the latest standard provides.

As such, this request is a superset of the if/then/else one.

Note that the particular request for if/then/else support in our JSON Schema implementation is already tracked by related ticket SERVER-42035.
