Modeling (5/11/17)

Project Name:
Proposed name for the project: Modeling
Proposed name for the repository: org.onap.modeling

Project description:

The unified model-driven approach uses unified source meta-models (that represent source models), for model transformation into unified target meta-models (that represent target models). The key function of any model-driven approach is the mentioned transformation, but also the fact that model-driven system uses models as sources of data for generating processes/codes and following workflows (not code development as source) – this way, the system can be more flexible and future proof, easy to update and use for cross-platform solutions since the “only” thing needed is Model update and manipulation through Engine.

The word “unified” here refers to unified information models that are used in the system to describe meta-models and models in a platform independent way. AAI should use data models in runtime (ex. for LCM events), APIs use data models to expose specific data types with relationship to achieve programmability, while blueprints are updated through model transformation process where iteration of queries and manipulations (using the transformation engine) are executed on the source (ex. VNF) and target model (ex. Blueprint).

This project will produce unified and consolidated data models together with related projects
This project will explore A&AI/SDC data for a common information modeling
This project will provide the foundation and framework to oversee and create a common ONAP information model across all ONAP projects
The information and data model will cover: Resource models (that contain VF and VFC), Service models (that are composed from resource models), Deployment/Lifecycle models and application modeling
The modeling group's objective is to define a unified model-driven approach for ONAP’s components
This project will investigate ways to meet ONAP’s overall orchestration needs by aligning and integrating its top-level imperative workflow capabilities with TOSCA-based declarative or imperative execution environments.
- this work is related to Service Orchestrator (5/14/17) and VF-C: Virtual Function Controller (5/16/17) about their implementation of workflow execution:
This project will provide the guideline and frame work for workflow in other ONAP projects to stitch together

Scope:

Tools and specification of CIM (Common information Model) and DM (Data model)
Prioritize needs of data model in the various projects.
Document: guideline, process of how to define the data model and information model, and design the architecture of workflows
Code - parsers (unified API interfaces) and tools (translators)
Support Use cases of ONAP: vCPE, vVoLTE, vFW, et al.

Architecture Alignment:

How does this project fit into the rest of the ONAP Architecture?
