Notification vs. Request vs. Order

Title: Notification vs. Request vs. Order

Hi EI folks,

In reflecting on Ed Koch’s presentation last week, I start to think about the semantics of “Notifications”, “Requests”, and “Orders”.  Especially in the context of normal business transactions (Purchase Orders, Requests for Quotes, Price Notifications.

I think part of what Ed was saying (and Ed I’d like to hear your thoughts) is that the presence of price information in the ESI messages don’t identify the nature (i.e. sender’s intent) of the message.  I think it would be good if the ESI message/information is clearly identified as “Notifications”, “Requests”, or “Orders”.  Here is how I think of them:

From the sender’s perspective:

Notifications: Here is some information.  I want to be sure you received it because that is my responsibility.  I don’t care what you do with it (I might care what the majority of recipients do).

Requests: I’d like you to do XYZ.  Please let me know if you will do it or that you did it and maybe what the results are.

Orders:  We agreed that I could tell you to do XYZ.  I may want you to confirm that you will and/or have.  I might only care to learn after the fact that you did not do XYZ because I need to punish you.  I may or may not be able to do anything with the knowledge that you plan to defy our agreement.

Part of the difficulty I have in reconciling the CA OpenADR and the concept of the ESI is that the paradigm in my head for the DRAS is one system (Server, Client).  I imagine the ESI “interface” to be between two systems (“Peer to Peer”).  Not sure if that makes much of a difference at the Type level.

I am advocating that the ESI we define have clear options for distinguishing between “Notifications”, “Requests”, and “Orders”.

Thoughts?
