Publishing State

Code subject to change

The RESTrict Framework is currently in its early design and development phase. The following protocol description will change.

When the state of a resource is published to the client or other services, the protocol has the following definition for a message.

• An entry indicating what kind of mutation has occurred (created, modified, deleted)

• The type of resource the message represents

• The URI for the resource

• For each attribute in the resource:

  • The name of the attribute

  • The type of the attribute

  • The value of the attribute

    • If the value is scalar value, then it is just that value

    • If the value is another resource, then it is a recursive definition OR a URI for the resource

  • A cryptographic hash of the value of the attribute

When the state of the resource is requested by a client, the protocol has the following definition for a message.

• The type of resource the message represents

• The URI for the resource

• For each attribute in the resource:

  • The name of the attribute

  • The type of the attribute

  • The value of the attribute

    • If the value is scalar value, then it is just that value

    • If the value is another resource, then it is a recursive definition OR a URI for the resource

  • A cryptographic hash of the value of the attribute

Novel to the RESTrict Framework is a cryptographic has of the attriute value. This is done to allow non-persistent store detection of changed values.
