VNF Lifecycle Operation Granting interface
==========================================

Grainting interface for giving VNFM a permission from NFVO to enable to run VNF
lifecycle operations and its configurations
as defined in ETSI `NFV-SOL 003 v2.6.1`_ for so called
v1 APIs, or `NFV-SOL 003 v3.3.1`_ for v2 APIs.

Granting Interface Support
==========================

No all the APIs of v1 and v2 have been implemented in Tacker's granting
interface yet.
The purpose of this section is to show the progress of implementation of the
APIs.
