a. A recipe specifier may reference a recipe that is in a namespace and not in the recipe executor’s storage.
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.

Message Flow with Completion Notification

The second type of message flow may be used for notifying the service user of RMEDnldVer, RMEVerify, and
RMESelect that individual operations on recipes have been completed.
A third type of message flow consists of a single notification message, shown in Figure 11.3, sent by the recipe
executor to inform the originating namespace of a new or changed execution recipe. (See Section 11.2.10.)

Change Notification Message Flow
14.3 RMEDnldVer — The service user may request the recipe executor to download and verify an execution recipe.
All unverified downloaded recipes are verified automatically. The service user may optionally specify a forced
overwrite of any pre-existing unselected recipe with the same identifier. A currently selected recipe shall not be
overwritten. If forced overwrite is not specified and a recipe with the same identifier is already in storage, the
request to download is denied and the recipe is discarded.
If the recipe executor performs a verification of the downloaded recipe, and if the verification is successful, then it
shall return the information provided by the conditional parameters.
Parameters for RMEDnldVer are listed in Table 14.3.
Table 14.3 RMEDnldVer Service
Parameter Req/Ind Rsp/Conf Description
RERcpSpec M - Destination specifier of the execution recipe.
REOWCode M - Indicates if a forced overwrite is requested.
RERecipe M - The execution recipe.
REVerData - C Information concerning the successfully verified recipe. Omitted if
recipe has no external references or fails verification.
REStatus - M Information concerning the results of the operation.
14.4 RMEVerify — The service user may request the recipe executor to verify an execution recipe. If the
verification is successful, then it shall return the information provided by the conditional parameters.
Parameters for RMEVerify are listed in Table 14.4.
Table 14.4 RMEVerify Service
Parameter Req/Ind Rsp/Conf Description
RESpec M - Specifier of the target recipe executor.
(List of) RERcpID M - Identifier of the recipe.
REOpID C C(=) Operation ID, used where multiple confirmations may occur. May be
null or omitted where the service initiator does not request a new
service, until all confirmations for the outstanding service have been
received.
LinkID - M LinkID is set to zero if, and only if, no further completion messages
will be required.
(List of) REVerData - C Information concerning the successfully verified recipe. Omitted if
recipe has no external references or fails verification.
REStatus - M Information concerning the results of the operation.
