scope:

This Recommendation provides the metadata framework for the closed-loop automation lifecycle management of Network as a Service (NaaS) service, specifically in the environments of development and operations (DevOps) and continuous integration/continuous delivery (CI/CD). This Recommendation covers the following aspects:

- general description of metadata for NaaS service lifecycle management;

- metadata in NaaS service;

- metadata framework for NaaS service lifecycle management;

- NaaS service operational policy framework.

This Recommendation also provides Appendix I describing:

- metadata applicability in NaaS service lifecycle management.

NOTE 1 - The objective in defining a metadata framework of NaaS service lifecycle management is not to invent new metadata, but rather to make the existing metadata interoperable and integrated in the closed-loop automation management of NaaS service, especially in the environments of DevOps and CI/CD.

NOTE 2 - "Metadata" in this Recommendation refers to NaaS service data model, NaaS service operational policy data model and NaaS resource data model.
