Information provided without comment... draft-ietf-ipfix-information-model-rfc5102bis has approached the problem of an information model without a modelling language. I think the problem it is solving is simpler than in I2RS. You might ask the Ops ADs for input on this topic. A From: [email protected] [mailto:[email protected]] On Behalf Of Alia Atlas Sent: 23 January 2013 21:44 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
