Types of Introspection Metadata

The Live Framework provides introspection metadata in the following ways:

    * The OPTIONS HTTP verb
    * The $metadata query parameter
    * The ResourceDescription class (managed clients)

The OPTIONS HTTP Verb

The OPTIONS HTTP verb is supported for every resource and resource collection. Thus, performing an OPTIONS request is valid for both of the following example URIs:
Copy Code

https://user-ctp.windows.net/V0.1/[UserID]/Mesh/MeshObjects
https:// user-ctp.windows.net/V0.1/[UserID]/Mesh/MeshObjects/[meshObjectID]

A successful request is returned with a status code of 200. The response body contains information on which HTTP methods are supported for the resource in question, as well as information related to these operations (possible status codes, common request headers, common response headers, and so forth). The Live Framework returns this information in either POX, HTML, or JSON format, with POX being the default format. The latter two formats can be requested by using the $format query parameter.
