User Story

As a Data as a Product developer
I want the data-platform-catalogue to support CRUD operations on Data Products (not just data 'entities')
So that I can interact with Data Products in the deployed Catalogue using our DaaP API

Proposal

Building off the work in ministryofjustice/analytical-platform#2779 that added the DataHubCatalogueClient class to the package, we can add support to that class (later to the base class if needed) for the dataProduct entity (which doesn't appear to exist in the python emitter sdk at the moment (v0.12.0).

Definition of Done

• Mapping of our data product schema to the DataHub schema (object pass through)
• Data Products can be registered in DataHub via the client object
• Tests exist (similar format to existing tests, or better) and are passing
