14.1 Recipe Executor Message Parameter Dictionary — For purposes of transferring a recipe, it is regarded as
having two types of sections: an attribute section containing the recipe’s attributes, and a body section consisting of
the body. The attribute section is always transferred first, and the attributes ExecAttrLength
, ExecAttrChgTime,
AttrLength
, AttrTimestamp, BodyLength, and EditTime are always sent first, in that order. This allows the length
information to be immediately determined by the receiver.
Descriptors are also regarded as consisting of sections for the attribute descriptor, the generic attribute descriptor,
and the body descriptor.
Each start of each section is identified with a text string reserved for that section type.
Table 14.2 contains the definitions for message parameters.

14.2 Message Flow — The flow of messages defined in RMS, between the service user and the service provider,
are of three types. The first type, illustrated in Figure 14.1, is the most common and applies to all recipe executor
operations except for cases of RMEDnldVer, RMEVerify, and RMESelect. A request message is sent from the
service user, and the recipe executor returns a response message containing the appropriate information. All
activities that occur as a result of the request are completed before the response message is sent.
Figure 14.1
Basic Message Flow
The second type of message flow, illustrated in Figure 14.2, is used for messages that specify an operation to be
performed that may require more time for completion than is allowed between a request and a response. In this case,
the response to the request indicates an intent to complete the operation rather than actual completion. The operation
is then performed on each of the specified recipes in turn, until each operation has completed, either successfully or
with errors. Any errors that occurred are reported in the completion message.
