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.

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?  
  

  
 

  
Best,

  
Aaron

    Service

    
Aaron,

    
 

    
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.

    
 

    
Best 
    regards,
