Toby,
I believe this is a fair assessment. The interactions
between the EMS and the external ESI are more appropriately communicated using
XML and web services.
Then, at the EMS level, the systems would communicate using
BACnet, LonWorks, OPC, HAN, DALI, etc.
Regards,
Sharon

In terms of the smart grid
diagrams, outside communications should be with Energy Services Interface
(ESI), which is something different than the Energy Management System (EMS).
Makers of BACnet, LON, HAN, DALI, et al will each figure out what the middle
layer is. Oft times, the enterprise will be in between the ESI and any
EMS. It certainly will be in any industrial environment…
BACNET, LON and friends are out
of scope…

Enclosed is a pass on the
document that Toby sent out. I mostly tried to answer some of his
questions and added some comments of my own.
Here are some general
comments:
It looked like there is some
material missing at the end.
Clearly there needs to be some
verbiage added concerning security requirements.
There needs to be some meat
added for the interaction and data models. Perhaps adding in some of the
diagrams from the spec will fulfill this requirement.
We need to give some thought to
what we are going to do with the various interfaces, i.e. BACnet versus REST
versus SOAP, etc.
