Error and short-fuse comments
In the interest of time and ease of adoption, I prefer using GML directly.  -Rish

RE: [energyinterop] Error and short-fuse comments

I believe 2 or 3 will be the best solution.  I don’t believe the IRC is using GML to define a resources location.  It’s a system  location, so geographic information is not accurate enough.  A resource could be miles away from its actual connection point to the grid, but closer or in another geographic connection point to the grid.

Re: [energyinterop] Error and short-fuse comments

Numbers refer to the *3* routes, numbered 1 through 4 below...
I think 1 and 4 aren't candidates. They share the same problem - they focus on only the geospatial aspect of the interface. This loses the capabilities which we spent a great deal of time on, including eliminating things like service delivery point, Pnode,  Apnode, etc.
The point is that emixInterface generalizes the notion of "location". And that that generalization is important.
Of 2 and 3, 2 is the simplest workaround keeping "location", and 3 is my preference.
Why would we have a "location" for BOTH the ResourceType (inherits from EnrolleeType)

AND in the contained emixResource? So another choice might be to give up the word "location" and do 3 as it directly allows any emix interface.
Thanks!

Good development of the pros/cons Toby, however, on balance I come down on the side of referencing GML directly.

Referencing GML directly, if it diverges, is a single order of divergence.
Referencing GML via EMIX, if there is divergence, potentially creates two orders of divergence.

Ok, Bruce has zoomed in on an unexpected feature of XML. This feature breaks the Resource location. See below for thread.

The abstract type is inherited properly. It breaks the substitution group rules, though. To recap:

<type name =”fooType” abstract=”true”>
<element name=”foo” type=”fooType” >
<type name =”fooType” abstract=”true”>
<element name=”notFoo” type=”fooType” >

<xs:element name="fooFighter" type="emix:fooFighterType" substitutionGroup="foo"/>
<type name =”fooFighterType” >
                <xs:extension base="fooType"/>
</type>
<xs:element name="fooLover" type=" fooLoverType " substitutionGroup="foo"/>
<type name =”fooLoverType” >
                <xs:extension base="fooType"/>
</type>

fooFIghter and fooLover are substitutes for foo
fooFIghter and fooLover are NOT substitutes for notFoo

We have three routes we can go.
(1)
WE can make location a name (or reference) to an existing concrete type,
(2)
we can make location a container for an EMix Interface
(3)
We can simply stick an EMix Interface in there can get rid of the word Location.
(4)
We can lose the entire EMIX stuff and refer to the GML directly

Discussion:
1) Location is all that matters, we don’t care about any  of the other possible meaning of interface, we want a geographic location only. The counter-argument is that what matters may well be “what substation is this resource attaching to” which is covered  by the interface but not by the location

<element name="location"
type="emix:ServiceAreaType"/>

2) If we just put an Emix Interface there, no one will understand it. The word and concept Location is important, especially  since a Resource, could, in concept, be a collection of [devices] each with its own EMIX Interface.

<element name="location"
type="locationType>
<type
="locationType>
<element ref=
"emix:emixInterface"/>
</type>

3) Emix defined it. Add an annotation and be done with it. THe other interfaces (see 2) will be embedded inside emix:resources  anyway, so why worry about it.

<element name="emixInterface" type="emix:EmixInterfaceType"/>

4)
We can lose the entire EMIX stuff and refer to the GML directly. It is just confusing to reference  that EMIX stuff. There would be no issue if we went directly to the GML. Well, we would have to include the gml profile defintions stuff, and it could, in concept, diverge from the normalization of GML performed in EMIX. The down-side is that if a future version  of emix defines standard gml profiles for, say “within 50 feet of a Transmission line” or “distribution zone associated with a sub-station” we will not inherit them.

<element name="location" type="gml:AbstractFeature"/>

OK, I see the symptom in xmlspy schema view.

Not sure why, though. Let me poke around further.

Not sure what is going on there. I will wiggle the parts and see if something squeaks.

EMixInterface is, of course, abstract. It relies either on inclusion of gml schemas (for spatial references) or EMIX Power schemas  (for node/meter/etc references). Any chance those are not being resolved properly?

The type shows up in the latest version, but I have to resolve it manually.
