Open APIs

We are implementing a new ServiceInventory function. During the design phase we faced an inconsistence between SID model and TMF638 API definition.
eg.: the SID model define the statuses of Customer Facing Service that may be the following enumerated values: 0: Operational and billable; 1: Degraded but billable; 2: In Violation and billable; 3: Operational but not billable; 4: In Test and not billable; 5: Being Deployed and not billable; 6: Failed. Ont he other hand the Service Inventory Management API v5.0 definies the following statuses for Service class: feasibilityChecked, designed, reserved, inactive, active, terminated, suspended.
How should we interpret these two definitions for service status?

The SID model statuses seems more aligned with the 'operatingStatus' introduced in v5. This has values "pending", "configured", "running", "degraded", "failed",  etc.
But even these are not fully aligned.
I would like to hear an opinion from a TMF expert.
