Nancy,

 

Thank you for your response. I do hope that the schema gets updated soon,
because despite Ira's contention that the document is definitive rather than
the schema, I am trying to make the document follow the schema.

 

The complex element AvailableResources (a term that needs some definition)
is in the inherited ServiceDescription element group. I can see that, when
in the description of a service, it applies to the resources available to
that service. I agree that these does not include resources available for
just one job.  It is not clear to me that this would not include resources
provided through the Resource Service if they are persistent.  

 

When applied in a System context, what is included depends upon how the
information is to be used.  English usage  gets a little muddy relative to
strict logic usage with words such as  "any" vs "all" . Your "any" response
to question 2 suggests to me that even if a resource is available to only
one service, it is included as a system element. This might be useful in an
accounting sense, but one still needs to view the Service AvailableResources
to see what can be used on a job. On the other hand, if the element includes
resources available to all supported services, this identifies resources
that can be used on any job, although perhaps not all. 

 

But I am still puzzled by AvailableResources  under Server as well as under
System.  At the present time there is no Subunit complex element under
System.  Each service does include a Configuration complex element that
identifies the subunits used by the service. The Subunits under Server
presumably include all of the subunits constituting the device. Similarly,
the AvailableResources  under Server would include all AvailableResources in
the device.  This would be redundant with AvailableResources under
SystemDescription if we take the "any" definition considered above.

 

I do not see the function of such redundancy. I think the concept of the
System is evolving. In some cases, as it SystemStatus, the System values
appear to represent the entire device. In others, such as
OperationsSupported, we consider the System as a distinct entity with its
own special operations. Perhaps System AvailableResources should identity
just those resources used by the system as a distinct functional entity? 

 

Opinions, please.

 

Thanks,

 

Bill Wagner

Hi Bill, 

According to my understanding, 

1. Yes, we agreed to change ResourceSupported to AvailableResources in
System. 

2. AvailableResources contains permanently installed resources readily
available to the MFD system, as compared to those needed to be downloaded
using Resource Service. I would say these are available to any supported
service in the device. 

3. AvailableResources complex element used to be under Server but not in
System. We have just started to define AvailableResources in System which
actually has the same semantics. So these two are redundant. But I think
it's useful to retain it in Server to serve as the base class for
AvailableResources in System. The relationship between the
AvailableResources under Server and that under System is just like the
relationship between the Subunits element under  Server and the Subunits
under the System. 

Pete said he will make sure we got the semantic right after the meeting. But
he is out these days, we should double check with him in the next
teleconference for the correct semantics. 

Regards, 
-Nancy

[MFD] MFD Overall spec questions

 

		




I have been working on what has turned out to be a major re-organization,
based on the comments at the June face-to-face. At this point, I have a few
rather low-level questions with respect to System as represented in the
schema.



1.     SystemDescription includes the ServiceDescription element group,
which includes ResourcesSupported. I have a note that we changed that to
AvailableRescources. Is that correct?

2.     In the System  context, does ResourcesSupported /AvailableRescources
deal will all the resources available to any supported service in the
device, or only to resources available to all supported services in the
device?

3.     How does this relate to the AvailableResources complex element under
Server, which is at the same level as System , Services and Subunits?

4.

Thanks,



Bill Wagner
