There= I could see 'ietf-yang-library:yang-library' data tree instead meaning= every 'module-set' and corresponding 'schema' need to be referenced by= some 'datastore'. The consequence would be that one must know the data= store of the data before they can be parsed, is that right? Moreover, f= or parsing one would also need the 'ietf-yang-schema-mount:schema-mount= s' data (which are found in the operation data in the example) but wher= e should the NETCONF/RESTCONF server (for instance) get them? > > Thanks for any clarification. > > Regards, > Michal [1] https://datatracker.ietf.org/doc/html/rfc8528 [2] https://datatracker.ietf.org/doc/html/rfc8528#appendix-A.2 [3] https://datatracker.ietf.org/doc/html/rfc8528#page-5 [4] https://datatracker.ietf.org/doc/html/rfc8529#appendix-A.3 > =5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F= =5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F= > netmod mailing list > netmod@ietf.org > https://www.ietf.org/mailman/listinfo/netmod
