Liaisons referred by this one NMOP WG Reply to the ETSI ISG ZSM LS on Network Digital Twin
Body 
1. Overall description:
The ETSI ISG Zero-touch network and Service Management (ZSM) would like to
thank the NMOP WG for replying to our Liaison Statement and for informing us
about the work you are doing related to the deployment and usage of YANG
topology modules as a Digital Map. Such a Digital Map underpins a key part of
the information flow by which a Network Digital Twin will be kept synchronized
with its real-world counterpart.

In particular, the ISG would like to confirm that we are working on NDT topics,
and their related use cases, in ZSM architectural terms, and on how to use NDT
technologies in order to enable a high degree of network automation. We would
like to confirm that we would consider your proposed Digital Map, and the
models it finally will encompass, as an authoritative source with respect to
the network technologies addressed by IETF.
