Hi Wes,
                 I've been working on integrating the SPDF UML into the 
existing UML model and also sorting out the schema. A few things have come 
up;

I had to change the name of a couple of classes to avoid namespace clashes 
in the schema
I don't think the TrajectoryDetails class is required, and would suggest 
that the trajectoryRef attribute is moved to the ServicePkg class with a 
caridinality of 0...1.
Rather than referencing the EventSequence, ConfigurationProfileContents 
and DDORScanPattern classes directly I would do so via abstract classes so 
that if required Agency specific EventSeqeunces, 
ConfigurationProfileConstants and DDORScanPattern classes could be used. 
(This also would be consistent with the SMURF and would imply that the 
abstract  EventSequence, ConfigurationProfileContents and DDORScanPattern 
classes should be defined in (Issue 2) of the CDF book, as should be the 
frequencyBand and serviceType attributes - this also needs a change to the 
SMURF)
I have a bit of a problem with the named BriefServicePkg and 
FullServicePackage. My understanding is that the BriefServicePkg actually 
is a complete service package and that the FullServicePackage is exactly 
the same except that it contains in addition the EventSeqeunce and 
ConfigurationProfiles related to the ServicePackage. In this case I would 
suggest that the BriedServicePkg be renamed to ServicePkg, and the 
FullServicePkg to EnhancedServicePkg.
I would suggest that the BriefSerivePgk (or ServicePkg if the above 
suggestion is accepted) contains references to the relevent 
EventSequences, Configuration Profiles and DDOR Scan Patterns.
An additional suggestion is that for the BriefServicePkg 2 additional 
classes should be added. One would contain a list of modified parameters 
(if any) for the EventSequence, cardinality 0...1. The other would contain 
a list of modified parameter for the configuration profiles. There would 
be one of these for each Configuration profile related to the service 
package which had modified parameters.

One other point, what is the use case for the FullServicePkg ?, I have a 
vague recollection of this being discussed at one time but I've forgotten 
what the justification was. Bearing that in mind I'm wondering whether the 
FullServicePkg is actually required, it strikes me that providing the 
references should be sufficent, but as I've said I can't remember the 
origin of the FullServicePkg

Cheers for now,

Colin

Hi Erik, I?m not sure that I?ll make the meeting today due to a couple 
conflicts.  However, in the next couple of days I should have no problems 
to make the small SPDF book change that you mentioned last time, and get 
the revision uploaded.
