For an overview of information and data models (and the distinction between them), there is also RFC 3444 http://www.ietf.org/rfc/rfc3444.txt
Just as a comment, I like the pyang-ish data tree as a summary of the model structure as well. A short-hand for some of the "cornerstones" of the model, then more specifics can be found in the more formal definition. I would think what is currently there should provide more or lesswhat is needed, hence I'd hope the group would be able to just reuse that (building any extensions on top if and when needed, but not introducing a new variation). Kind regards --- Alex From: [email protected] [mailto:[email protected]] On Behalf Of Alia Atlas Sent: Wednesday, January 23, 2013 1:44 PM To: [email protected] Subject: [i2rs] format for information models As part of the proposed i2rs charter, the WG would need to produce information models. I know there's lots of interest in this and it would be great to agree on a format that we'd like to see the information models in. >From my perspective (learning all the time), an information model is to >describe the information and purpose of the data needed in the model, without all the details that make the reasoning and structure hard to understand (and also take lots of time to develop). Of course, there's Wikipedia's definition (http://en.wikipedia.org/wiki/Information_model) and various RFCs that include information models (RFC 5102, 3585, etc). Frequently, the information model can just be in English. Based on some side conversations, I'd like to see if we can discuss and agree on a format to try for the information models. What I'd suggest is basically a data-tree (similar to the TreeOutput from pyang - seen at http://code.google.com/p/pyang/wiki/TreeOutput) and then information per data item. The required information would be a description, a type, and, if appropriate, a reference (to where else the concept is defined). What do you all think? Any better/different ideas? Alia
