3GPP TS 28.561 Ndt Nrm API

OAS 3.0.1 definition of the NDT NRM. An OpenAPI 3.0.1 data-model-only document (no paths; it defines the schemas/Network Resource Model consumed by the Provisioning and Performance management services), API version 19.3.0, published verbatim by 3GPP in 3GPP TS 28.561 as part of the Management Services (SA5 OAM) suite and mirrored in the public 3GPP Forge GitLab repository.
