A URI doesn't have metadata that corresponds to HTTP headers (like

Resources also don't innately have metadata - they handle requests and
provide responses. The responses can easily vary over many of the
interesting pieces of metadata - so there isn't a one-to-one mapping from a
resource to a single canonical content-type for example.

It would be sensible to describe the requests a particular resource
supports - especially in terms of the Accept type of headers - and perhaps
reflect the kind of responses the might be given.

For example, you might say that a response would contain a
content-type='text/plain' when the request contains an accept='text/plain',
or if the request contains a user-agent='Mozilla *' or something.

Alternatively, you may be simply trying to describe the response to a GET
request - but since there are many possible varying representations, you
probably need to include something of the request that generated that
