I'm sorry, but your question appears to be incomplete: "If I were to format an ObjectId in..." Could you please clarify what you would like to know about formatting an ObjectId? For example, are you asking about formatting object identifiers for Ory Keto (Ory Permissions), or something else related to Ory? Please provide more details so I can assist you accurately.

In Ory Keto (Ory Permissions), the

Article:

prefix in

Article:abcdefg12345

is significant because it typically denotes the namespace of the object. Namespaces in Ory Permissions are used to scope objects and subjects, and they define which relationships and permission rules apply to those objects. When you query permissions (for example, using

ory is allowed

or the Keto API), you usually specify the namespace and the object separately. For instance, in the CLI, you would use:

ory is allowed <subject> <relation> <namespace> <object>

So, for your example, if you have an object with ID

abcdefg12345

in the

Article

namespace, you would query it like this:

ory is allowed <subject> <relation> Article abcdefg12345

Here,

Article

is the namespace, and

abcdefg12345

is the object ID. The

Article:

prefix is not part of the object ID itself but is used to indicate the namespace in documentation and relationship notation. When using the CLI or API, you should provide the namespace and object as separate parameters, not as a single string with a colon. Summary: - The

Article:

prefix indicates the namespace. - When querying, provide the namespace and object ID separately, not as a single string. For more details, see the [Ory Keto documentation on namespaces](https://www.ory.sh/docs/keto/concepts/namespaces) and the [CLI usage](https://www.ory.sh/docs/cli/ory-is-allowed#ory-is-allowed) for permission checks.
