Hi Joe,

We discussed YL in today’s meeting and consensus was to have it in both YL and capabilities.

Good question about default schema, this could indeed be handy.

Regards,
Reshad.

Subject: Re: [Netmod-ver-dt] Version selection for NETCONF

Why not advertise in yang library since both RC and NC need this?  Other than that, the RPC flow sounds right.  But what is the default schema?  Does the server flag one as default?

Hi all,

Last week (email + meeting) there seemed to be consensus on the use of “root path” method for RESTCONF.

For NETCONF, we discussed using capabilities. Extending the capabilities to include “schema versions” seems sensible, with 1 top-level schema per schema family where family is e.g. vendor-xxx-native, ietf, OpenConfig.

  1.  An example of schema-versions advertised: vendor-xxx-native_1.2.1, vendor-xxx-native_2.0.0, ietf_2.3.0. We also need an RPC for the client to select which schema-version (among the ones advertised by the server) it wants to use.
  2.  If a client doesn’t call the SetVersion RPC, then the server’s behavior is to resort to default schema version (when multiple versions of schemas are supported).
  3.  If a server doesn’t advertise any schema-versions, client doesn’t call SetVersion RPC and both behave as they do today.

Thoughts on this?

Regards,
Reshad.
