The OOF will provide a library of adapters for common ONAP systems. These can be directly used in data specification templates of the applications. In the initial release, these will include adapters to Policy, A&AI, SDN-C, Multi-Cloud, and SDC (additional "stretch goals" for this release include SDN-C, Microservice Bus). As new use cases are implemented, this library will be augmented by new adapters to other services.
Translation Modules
The OOF will provide modules for translating policies into constraints for the optimization environment. When an underlying minizinc model is used for optimization, it is translated into a minizinc constraint (either via a data specification template or directly from policy). For custom optimizers, these constraints will be translated to the input format expected by the optimizer via the data specification template. The Homing and Allocation Service (HAS; described in the next section) uses a custom optimization module and hence uses the data specification template approach.
