Re: [netmod] [Netconf] development plan

["Joel M. Halpern" <[e-mail]>]

If there is an arrow in figure 1 of the I2RS architecture implying that 
an I2RS agent manipulates the config data, then we need to fix that. 
The intention of the authors (and the intention agreed in earlier 
documents) is that I2RS does not mes with config data.
The amplification in the architecture document is that I2RS simply does 
not mess with any persistent data storage at all.  I2RS state is lost at 
reboot.  The working group sounded happy with this proposal in Berlin. 
We will see what happens on the list.

Yours,
Joel M. Halpern,
I2RS Architecture coauthor and netconf/netmod spectator.

So if Fig. 1 indicates that I2RS agents interact with Local Config, I assume it has to do so as a compliant NETCONF client. So "config true" data stay fully in the NETCONF realm.
