There is a lot of talk around interoperability standards lately.Following these discussions, it seems to me that people are intermixing a lot of different topics:
a) Log format (syntax)
b) Event transport
c) Event classification (also called taxonomy, categorization, grammar)
d) Logging recommendations (what events specific devices should report AND what fields they should contain as a minimum
I would really like to see future discussions broken up into these four groups!
