Introduction to RDM

A Resource Description Message (RDM) is a messaging format which two processes can use to exchange resource descriptions across a network. In RDM, one process (a client or agent) sends a request RDM message to a remote server which processes the request, then sends a response RDM message, similar to the HTTP/1.0 request/response model.

For more information about RDM, see:

For example, you can send an RDM request to a search engine database to request RDs that match certain criteria. The search engine will send back an RDM response that contains the requested RDs (for example, all documents containing the string style_sheets).
