+==== Permission Ticket
+
+A Permission Ticket is a special type of token defined by the https://docs.kantarainitiative.org/uma/rec-uma-core.html[UMA] specification that provides an opaque structure whose form is determined by the authorization server. This
+structure represents the resources and/or scopes being requested by a client as well the policies that must be applied to a request for authorization data (RPT).
+
+In UMA, permission tickets are crucial to support *person-to-person sharing* and also *person-to-organization sharing*, introducing the possbility to cover from the most simple to the most complex
+*authorization workflows*, where resource owners and resource servers may have complete control over their resources based on fine-grained policies that govern the access to these resources.
+
+During the UMA flow, permissions tickets are issued by the authorization server to a resource server, which in turn returns it back to the client trying to access a protected resource. Once the client
+ receives the ticket, it can request for a RPT (a final token holding authorization data) by sending the ticket back to the authorization server.

+Resource permissions can also be used to define policies that must be applied to all resources with a given link:../resource/create.adoc#_type[Type]. This form of resource-based permission can be very handy when you have resources sharing very common access requirements and constraints.

+Usually, resources within an application can be categorized (or typed) based on the data they encapsulate or the functionality they provide. For instance, a financial application manages different
+banking accounts where each one belongs to a specific customer. Although they are different banking account, they usually share some very common security requirements and constraints, where those are globaly

+* Only the owner can manage his account
+* Only allow access from the owner's country and/or region
+* Enforce a specific authentication method
+* And so forth ...

+To create a typed resource permission, just click on link:./create-resource.adoc#_apply_resource_type[Apply to Resource Type] when creating a new resource permissions. Once you do that,
