Backbase OpenApi Tools

The Backbase Open API Tools is a collection of tools created to work effeciently with OpenAPI

It currently consists of

• RAML 1.0 Converter to OpenAPI 3.0
• Create Diff Report between 2 OpenAPI versions of the same spec (Based on https://github.com/quen2404/openapi-diff)
• Decompose Transformer to remove Composed Schemas from OpenAPI specs to aid in code generators
• Case Transformer to see how your API looks like when going from camelCase to snake_case (transforms examples too)

The project is very much Work In Progress and will be published on maven central when considered ready enough.
