SdaiModelVersion *newModelVersionId,
SdaiInvocationId *edmiInvocationId);
|
Stores the current version of an edmModel using the built in revision control system of edm.
...
Any number of versions may be generated for an edmModel. All new
...
versions of an edmModel will be a appended to the list of modelVersionIds in the VERSIONS attribute of the model.
