Style Guide for defining APIs in Swagger (& OpenAPI 3.0)
Recommend Swagger toolset to develop, validate and publish Swagger / OpenAPI 3.0 API Specs (in JSON or YAML) (e.g., SwaggerHub)
Select a tool for generation of API Reference documentation directly from Swagger / OpenAPI files (using Redoc for example which creates a consistent standalone HTML file)
Create common and uniform Conceptual API Documentation describing each API and provides quick start and usable TIFY(try it for yourself) samples
Start with a common ONAP RST template, instructions, and examples
Select and work with a few ONAP projects to pilot the approach for Frankfurt (e.g., External API, SO, etc.)
