==== Project Name: ====

  * Proposed name for the project: ''Model Oriented Virtualization Interface''
  * Proposed name for the repository: ''movie''
  * Project Categories:  ''(Requirements) ''

==== Project description: ====
While OpenStack is a competitive candidate for VIM, existing interfaces provided by OpenStack include three major parts: compute, storage, and network. The IaaS service oriented NBI leaves a lot of detailed work for the upper layer applications (e.g. orchestrator). 

The proposed project is to provide a more abstract VIM NBI alternative by extending the general cloud platform to to simplify the orchestrator and VNF manager, and make it easy for resource access, connection generation, flow identification, policy operation, etc. This higher level abstraction gives the upper layer applications another option in addition to the combination of openstack existing interfaces and extentions developed by other OPNFV projects.

The service oriented NBI extension encapsulate higher order operations appropriately in the NFV problem domain. It will build upon existing projects, like promise, copper, VNFFG, and so on, and their APIs to implement the NBI and find gaps when the NBI cannot be implemented by existing projects.

To achieve the NBI consistency, we can use the Model Driven Architecture (MDA) approach and define system functionality using platform-independent models. Interfaces can be generated automatically with well defined models.
==== Scope: ====

**Describe the problem being solved by project**

This project is to provide a more abstract VIM NBI alternative to better fitting the upper layer applications. With a set of higher level information models and interfaces, we can address most use-cases in a systematical way. The proposed project is intended to (tentatively scheduled):
  * document typical NFV use-cases for high-level functional abstraction, and find gaps between OpenStack API and applicaitons;
  * abstract the service oriented VIM NB models and interfaces;
  * work together with other entities to achieve collaboration and synergy;
  * provide an open source implementation for the NBI extension. 
  * and coordinate integrated testing and release testing results.


**Specify any interface/API specification proposed**
