RDM Body

The RDM message body contains any data needed to carry out the request. For example, if the header is rd-request, which indicates a query request, the body must contain the query criteria or scope. For example, if you are sending a request to find all documents that contain the string varrius, then the body must be SOIF object whose schema-name is RDMQuery and whose scope attribute is varrius:

@RDMQUERY { -
    scope{7}:varrius
}

If the RDM message is a query request, the body of the message can also indicate which attributes of the resulting RDs are wanted, the number of results, and sort preference. For example, the following search criteria in the RDM body specifies the URL, title, author, and last-modified attributes. The result set contains at most 10 hits and the resulting set is ordered by the title attribute:

@RDMQUERY { -
    scope{7}:varrius
    view-attributes{30}: url,title,author,last-modified
    view-hits{2}: 10
    view-order{5}: title
}

If the RDM message is another kind of request, such as a Schema-Description-Request, a Server-Description-Request, or a Status-Request, the body of the message should contain appropriate data. See the relevant document for more details on RDM bodies.
