Based on the information provided in the extracts, you can define relationships and permissions in the Ory Permission Language (OPL) within your

CreateAppointment

class. Here's an example of how you might structure it:

typescript import { Namespace, Context } from "@ory/keto-namespace-types"  class InsuranceProfile implements Namespace {}  class InsuranceProfileDetail implements Namespace {}  class CreateAppointment implements Namespace {   related: {     insuranceProfiles: InsuranceProfile[]     insuranceProfileDetails: InsuranceProfileDetail[]   }    permits = {     createGroupAppointment: (ctx: Context): boolean =>        // Define your permission logic here. For example:       this.related.insuranceProfiles.includes(ctx.subject) && this.related.insuranceProfileDetails.includes(ctx.subject)   } }

In this example, the

CreateAppointment

class has relationships with

InsuranceProfile

and

InsuranceProfileDetail

. The

createGroupAppointment

permission is a function that takes the context and returns a boolean. You can define your permission logic within this function. Please note that this is a basic example and you might need to adjust it according to your specific needs and logic. For more information on how to create a permission model, you can refer to the [Create a permission model](https://www.ory.sh/docs/keto/modeling/create-permission-model) guide.

Based on the information provided in the extracts, you can encapsulate the

CreateAppointment

class within an

Appointment

class and perform a permission check for the

createGroupAppointment

permission. Here's an example of how you might structure it:

typescript import { Namespace, Context } from "@ory/keto-namespace-types"  class InsuranceProfile implements Namespace {}  class InsuranceProfileDetail implements Namespace {}  class CreateAppointment implements Namespace {   related: {     insuranceProfiles: InsuranceProfile[]     insuranceProfileDetails: InsuranceProfileDetail[]   }    permits = {     createGroupAppointment: (ctx: Context): boolean =>        // Define your permission logic here. For example:       this.related.insuranceProfiles.includes(ctx.subject) && this.related.insuranceProfileDetails.includes(ctx.subject)   } }  class Appointment implements Namespace {   related: {     createAppointments: CreateAppointment[]   }    permits = {     checkCreateAppointmentPermission: (ctx: Context): boolean =>        // Define your permission logic here. For example:       this.related.createAppointments.some(appointment => appointment.permits.createGroupAppointment(ctx))   } }

In this example, the

Appointment

class has a relationship with

CreateAppointment

. The

checkCreateAppointmentPermission

permission is a function that checks if any of the related

CreateAppointment

objects have the

createGroupAppointment

permission. Please note that this is a basic example and you might need to adjust it according to your specific needs and logic. For more information on how to create a permission model, you can refer to the [Create a permission model](https://www.ory.sh/docs/keto/modeling/create-permission-model) guide.
