Subject: RE: oBIX Discovery Service

Title: Message
As we name these scenarios, we are creating a new verb known the the oBIX language - in the same way that each object and method known in an OO environment creates a new verb.  This, is the essense of the Domain Specific Language (DSL) I was talking about last week.  You may recall that I suggested that a Web Service done right might be indistinguishable from a DSL.
While I am not sure myself what I mean by that, it do feel that it is a useful lense with which to look at oBIX, or the development of any language.

I do wonder if this belongs in the point service.  What we are talking about (scenes/shed levels) are nothing more than a group of set points.  It would certainly be a distinguishing feature between oBIX and all other XML point services.
BTW - We should be having these discussions on the mailing lists...

I think this, and what doug spoke about, are the *reason* for oBIX.  We have control systems, lots of control systems, now, and they generally do what they are supposed to.  What we do not have is standards-based a way to orchestrate them to meet the needs of the enterprise.
There are two purposes to oBIX
- Revealing properties if the networked control-system object to the enterprise to enable information-based decision making to the enterprise
- Proviiding a platform upon which hundreds of enterprise-based applications can be written using the interface to the control system.
This mioght be saying that Doug and Premisses might be ones for the Roadmap.

Subject: RE: oBIX Discovery Service

My initial thought is that this is not a function of the discovery service.  However, the discovery service should expose the node(s) and service binding(s) so that this can be done.
This sounds similiar to what Doug Ransom was talking about in the last cc.  Would this be something for the Power Management sig?

Subject: oBIX Discovery Service

I got to thinking about the oBIX discovery service.  As I understand it, a user (human being or application) can go to the facility, invoke the discovery service and get back a tree structure describing its phyiscal configuration and the addressable points (sensors, actuators, controllers etc) with their associated types.  It can then (if it has permission) extract data from those points and ultimately set certain parameters. 
It struck me that Premise Systems (http://www.premisesystems.com/ - recently bought by Motorola) has developed a concept that matches this idea very closely.  Although their primary target is residential, I know that their technology is being successfully used in commercial applications.  A very powerful 'tool' they use is the idea of a 'scene'.  This means that a pre-defined configuration of a building can be demanded.  This addresses one of the needs that Toby expressed: if you want to put the sports hall into 'event-mode' at 9pm for an unforseen basketball match then a simple (and obviously secure) command will set the heating, lighting, access, public address etc to the required set-points.
You may want to take a look at their software (free to download).  I'm thinking that it might also be a good idea to invite them to join our merry band.  Not only would we get Motorola into the fold but Dan Quigley, the president, is a well-connected ex-Microsoft guy who could bring quite a lot to the party.
