The JSON object you provided is related to the concept of "SubjectSet" in Ory's Keto service, which is a part of its identity and access management (IAM) solution. Here's a breakdown of the fields: - `namespace`: This is the namespace of the object and relation referenced in this subject set. Namespaces are used to scope objects and subjects, and they contain rules that define which relationships are looked up as part of a permission check. [source](https://www.ory.sh/docs/keto/concepts/namespaces) - `object`: This is the object related by this subject set. Objects are the resources that you want to manage. [source](https://www.ory.sh/docs/keto/concepts/objects) - `relation`: This is the relation between the object and the subjects. Relations encode the relationships between objects and subjects. [source](https://www.ory.sh/docs/keto/concepts/relation-tuples) - `subject_set`: This is a nested object that represents a set of subjects who have the same

relation

on an

object

. Subjects are the people or things that want to access these resources. [source](https://www.ory.sh/docs/keto/concepts/subjects) - `namespace`: This is the namespace of the object and relation referenced in the subject set. - `object`: This is the object related by the subject set. This structure is used to define relationships in Ory's IAM system, and it's crucial for managing permissions and access control. [source](https://www.ory.sh/docs/keto/reference/proto-api#subjectset)
