RE: [energyinterop] Groups -energyinterop-1-0-schema-wd23-wip7-edkoch.zi

Bill,

I tend to agree with the MW issue, but the structures we had put in place in wip 5 to accomodate not having to fix the units disappeared in wip 7. As I stated in my analysis I think this is OK and can easily live without them. In fact it makes the schemas much simpler to not have to accomodate them amd I now prefer not adding them back in.

I've been working all weekend at generating an eiEvent xml document from the existing schemas (i.e. based on my wip 7 changes). I've been writing a tool to allow me to generate them and I think I am close. I'm not altogether satisfied with how much application level code is necessary to supplement an xml document that has been generated directly from the schemas in order to generate something I consider a conformant xml document, but so far no major issues. I've encountered a couple of issues that may need to be fed back into ei. There was a particular approach for defining the schedules that I discussed with Toby last week. I am employing some of those principles in my xml generation. There was one idea in particualr concering where to put the signal intervals which I will try to revisit when I have completed working with the existing schemas.

BTW I've run into a couole of issues with ws-calaendar that I think I've seen come comments on already and may already be in the works. In particular I thought I saw some comment convering the recursive nature of the duration property. Is there a more recent version of the ws-calendar schemas that I should be using that address some of these issues?

thanks,

Ed --

I think this is very good.

One issue: megawatts crept back in (signalAmountMW) -- we need to have units (can be inherited) and quantity to accommodate global use. Other than that, I think this is my starting point to fix the payloads going to wd23.

Thanks for your hard work on this.

Modifications to wip7 schemas

Ed Koch

May 5, 2011

- Changed the substitution group of responseDescription from
signalInformationBase to eventDescriptionBase

- Changed the substitution group of eventBaselineDescription from
signalInformationBase to eventDescriptionBase

- Changed cardinality of EventDescriptorType:emixMarketContext to make it
optional.

- Moved eitc:eiEventSchedule from EiMarketContext and put it back in
EiEventType

- changed signalAmount back to signalAmountMW to fix the units. See below
for explanation:

Some of the typing information that we were using in the signal definitons
has disappeared in wip7. We may not need it if you consider the
following:

price - requires currency, but that can be part of the market context of
the overall event and does not need to be defined in the signal
definition.

priceRelative - unitless number

priceMultiplier - unitless number

signalAmount - this needs units, but if we change it back to signalAmountMW
then we can fix the units. We can express all valid numbers using this unit
and do not need to have variable units.

signalLevel - unitless number

signalPercent - unitless number

Since Toby removed the typing information then I suggest we leave it out.
