The NMDA draft includes the following in its terminology section:
- configuration: Data that determines how a device behaves. This
data is modeled in YANG using "config true" nodes. Configuration
can originate from different sources.
- operational state: The combination of applied configuration and
system state.
It would be nice to use matching terms, either by importing the
NMDA terms directly, or by mimicing them in this draft. If your
"operational data" means "config false" and NMDA's "operational state"
means both config true and config false, readers will be confused.
Also you say "operational state and other data such as statistics"
which inconsisent. Under either set of terms, statistics are
part of operational state.

"not sufficient to fully manage" is too broad a claim. Can I suggest
a more positive spin:
The Network Management Datastore Architecture (NMDA) defines a
new set of datastores that improve visibility into the device,
both in terms of the "intended" configurations values and the
true operationally "in use" values. Refer to
[I-D.ietf-netmod-revised-datastores] for details. Guidelines for
moving existing data modules to the NMDA are defined in
[I-D.dsdt-nmda-guidelines].
Thanks,
Phil
