This document updates both RFC 6241 and RFC 7950. The update to RFC 6241 adds new operations <get-data> and <edit-data>, and augments existing operations <lock>, <unlock>, and <validate>. The update to RFC 7950 requires the usage of I-D.ietf-netconf-rfc7895bis by NETCONF servers implementing the Network Management Datastore Architecture. REF Editor: please replace "I-D.ietf-netmod-revised-datastores" and "I-D.ietf-netconf-rfc7895bis" above with their final RFC assignments.
