Perhaps you can detail what it means to support multiple revisions of a module at the same time. Are you saying YANG needs a way to slice modules such that for example interface ethernet0 can support revision X of an Ethernet data model while interface ethernet1 supports revision Y of an Ethernet data model? If so, support for per resource data model revision is not really part of YANG nor is it really part of NETCONF I think. (Note that YANG does support mechanisms such as features that allow to design data models in a way that they can be backwards compatible.) /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
