Ontological term broker/Metadata

Metadata objects are returned as part of the metadata array associated with each Request object, and are described by the Metadata JSON schema file.

An example of a Metadata object conforming to this schema is:

{    "metadata_key":"type", "metadata_value":"protein", "created_by":{"href":"/user/1/","text":"anonymous"}, "created_on":"2010-09-23" }

Metadata are appended to requests by inserting objects conforming to the NewMetadata schema within the NewRequest object submitted to the /request/[request-hash] URL.
