Sure, I can guide you on how to model this in Ory using the Ory Permission Language (OPL). Firstly, you need to define your objects and their relationships. In your case, the objects could be

Appointment

and

Finance

, and the relationships could be the different permissions like

createAppointment

,

deleteAppointment

,

updateBlockouts

, etc. Here is a simplified example of how you might define these in OPL:

typescript import { Namespace, Context } from "@ory/keto-namespace-types"    class User implements Namespace {}    class Appointment implements Namespace {    related: {      creators: User[]      deleters: User[]      blockoutUpdaters: User[]    }   }    class Finance implements Namespace {    // Define relationships for Finance module here }

In this example,

creators

,

deleters

, and

blockoutUpdaters

are the roles that you mentioned. These roles are represented as relationships between the

User

and

Appointment

entities. Next, you need to define the permissions for each role. Permissions in OPL are essentially TypeScript functions that return a boolean value based on the relationships. Here is how you might define the permissions:

typescript class Appointment implements Namespace {    related: {      creators: User[]      deleters: User[]      blockoutUpdaters: User[]    }     permits = {      create: (ctx: Context): boolean => this.related.creators.includes(ctx.subject),      delete: (ctx: Context): boolean => this.related.deleters.includes(ctx.subject),      updateBlockouts: (ctx: Context): boolean => this.related.blockoutUpdaters.includes(ctx.subject),    }   }

In this example, the

create

,

delete

, and

updateBlockouts

functions check if the subject (the user) has the corresponding role. Finally, you can use the Ory Permissions API to create and manage these relationships and permissions programmatically. For example, to check if a user has permission to create an appointment, you would ask Ory Permissions:

is User:Bob allowed to create on Appointment:X

. Please note that this is a simplified example and the actual implementation might be more complex depending on your specific needs. You can find more information on how to create a permission model in the [Ory documentation](https://www.ory.sh/docs/keto/modeling/create-permission-model).
