Based on the provided knowledge sources, I don't have enough specific information to definitively answer whether identity schema in Ory supports UUID format validation. The documents provided don't contain explicit details about schema validation formats, including UUID. However, I can provide some related information that might be helpful: 1. Ory Kratos, which is part of the Ory ecosystem, does use identity schemas to validate identity traits. This is evident from references to

SchemaID

and

SchemaURL

in the identity object descriptions. 2. The identity object includes several UUID-formatted fields, such as

id

,

organization_id

, and fields within

recovery_addresses

and

verifiable_addresses

. This suggests that Ory does work with UUID formats internally. [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api) shows these UUID fields in the identity object structure. To get a definitive answer about UUID format validation support in identity schemas, you would need to consult Ory's documentation specifically about schema definition and validation, which is not present in the provided knowledge sources. I recommend checking Ory's official documentation or reaching out to their support channels for more precise information on this topic.
