I agree submodules can cause confusion, but I also agree with Mahesh that they can be useful to partition things for people using the modules. Especially for huge models (e.g. router vendor models). You can jump right to a subsection of the data (a bit like a document with chapters rather than one huge chapter). It can also be useful for consumers of the models for versioning (when you want to avoid multiple namespaces). If a model is made up of 30 sub-modules, it might be useful to know that the "bgp" part changed while the other parts of the model didn't. Jason From: netmod <netmod-bounces@ietf.org> On Behalf Of Mahesh Jethanandani Sent: Wednesday, August 5, 2020 6:43 PM To: netmod@ietf.org Subject: Re: [netmod] submodules the hidden benefits A contrarian view: I find the use of sub-modules helpful when I want to use separate files to maintain part of the module that is logically separate, while maintaining/restricting the use of them to a single namespace. The fact that tools have a problem with trying to compile a sub-module can be addressed in the tools themselves.
