The main NMDA document is draft-ietf-netmod-revised-datastores-10.txt,
meanwhile in the RFC editor queue. It may be a good idea to follow
NETMOD and NETCONF if people work on new protocols. ;-)

I assume that draft-dsdt-nmda-guidelines-01, draft-ietf-netconf-rfc7895bis-03 and draft-ietf-netconf-nmda-restconf-02 are the main documents to review before proceeding?
