Is your proposal to take out "This data is modeled in YANG using "config true" nodes."? Note that the NMDA document further defines o conventional configuration: Configuration that is stored in any of the conventional configuration datastores. o dynamic configuration: Configuration obtained via a dynamic datastore. o learned configuration: Configuration that has been learned via protocol interactions with other systems that is not conventional or dynamic configuration. o system configuration: Configuration that is supplied by the device itself. o default configuration: Configuration that is not explicitly provided but for which a value defined in the data model is used. There are corresponding origin attribute definitions. (With the minore caveat that the origin value for conventional configuration is intended since this is the datastore conventional configuration finally originates from.) /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
