Based on the information provided in the extracts, you can define permissions in the Ory Permission Language (OPL) using TypeScript functions. These functions take a context containing the subject and answer permission checks based on the relationships the object has to the subject. Here's an example of how you might define the

edit

permission for the

Post

namespace for anyone in the

Administrator

namespace. Please note that this is a hypothetical example and you may need to adjust it according to your specific needs and the actual structure of your namespaces.

typescript import { Namespace, Context } from "@ory/keto-namespace-types"  class Administrator implements Namespace {}  class Post implements Namespace {   related: {     editors: Administrator[]   }    permits = {     edit: (ctx: Context): boolean => this.related.editors.includes(ctx.subject),   } }

In this example, the

edit

permission is granted if the subject (the user making the request) is included in the

editors

relationship of the

Post

namespace. The

editors

relationship is defined as an array of

Administrator

instances, meaning that anyone in the

Administrator

namespace has the

edit

permission for the

Post

namespace. For more detailed information on how to define permissions in OPL, you can refer to the [Ory documentation](https://www.ory.sh/docs/keto/modeling/create-permission-model).
