     1  # Metaresources and Policy Attachment
     2  
     3  The Gateway API defines a Kubernetes object that _augments_ the behavior of an object
     4  in a standard way as a _Metaresource_. ReferenceGrant
     5  is an example of this general type of metaresource, but it is far from the only
     6  one.
     7  
     8  Gateway API also defines a pattern called _Policy Attachment_, which augments
     9  the behavior of an object to add additional settings that can't be described
    10  within the spec of that object.
    11  
    12  A "Policy Attachment" is a specific type of _metaresource_ that can affect specific
    13  settings across either one object (this is "Direct Policy Attachment"), or objects
    14  in a hierarchy (this is "Inherited Policy Attachment").
    15  
    16  This pattern is EXPERIMENTAL, and is described in [GEP-713](https://gateway-api.sigs.k8s.io/geps/gep-713/).
    17  Please see that document for technical details.
