Ok - it is less painful if we only have to deprecate the *-state nodes. However, what about secondary and tertiary implications of moving to NDMA? If we change a path from “interface-state-ref” to “interface-ref” to reference an interface, I’d hope no one would expect the old statement to be kept around… Thanks, Acee On 9/7/17, 10:40 AM, "netmod on behalf of Lou Berger" <netmod-bounces@ietf.org on behalf of lberger@labn.net> wrote: > > >On 9/6/2017 2:05 PM, Martin Bjorklund wrote: >> Kent Watsen <kwatsen@juniper.net> wrote: >>> ... > >>> 2) a new module name forces an update to other modules that >>> importing it (e.g., to resolve XPaths), that otherwise may >>> not need to be updated. >> This is a major drawback! >I think this is a compelling consideration. > >> >>> 3) the approach doesn't follow what draft-dsdt-nmda-guidelines >>> says in guideline (c), but this seems to be a minor point. >>> 4) republishing the old module with all nodes deprecated seems >>> off, but 7950 doesn't list 'status' as a substatement to >>> the 'module' statement, so what else can we do? >>> >>> Any other pros or cons? > >I think a pro is that for models that are not widely implemented or >referenced, they are more aligned with how we expect new NMDA-compatible >models to be structured. > >>> >>> >>> Another question is if all the modules have to be updated the >>> same way >> In general I'd say no.
