Re: [netmod] RFC 8199 on YANG Module Classification

Dear all,

The good news is that the module-classification is already added as a 
metadata in the yangcatalog.org.

        leaf module-classification {
          type enumeration {
            enum network-service {
              description
                "Network Service YANG Module that describes the
    configuration, state
                 data, operations, and notifications of abstract
    representations of
                 services implemented on one or multiple network elements.";
            }
            enum network-element {
              description
                "Network Element YANG Module that describes the
    configuration, state
                 data, operations, and notifications of specific
    device-centric
                 technologies or features.";
            }
            enum unknown {
              description
                "In case that there is not sufficient information about
    how to classify the module.";
            }
            enum not-applicable {
              description
                "The YANG module abstraction type is neither a Network
    Service YANG Module
                 nor a Network Element YANG Module.";
            }
          }
          mandatory true;
          description
            "The high-level classification of the given YANG module.";
          reference
            "RFC8199 YANG Module Classification";
        }
        description
          "These leafs are shared among the yang-catalog and its API.";
      }

This metadata can't be extracted from the module, but must be populated.
That's the reason why you would see "unknown" for most modules right now.
Ex: 
https://yangcatalog.org:8443/search/modules/ietf-l3vpn-svc,2017-01-27,ietf

When populated, this will provide the ability to search for service 
versus network elements YANG modules.
