This is a general theme to track progress on decoupling parts of the Repository and underlying Persistence parts, where several parts have been tightly coupled making it hard to:

• inject alternative implementations
• provide services / handlers on their own without requiring full repository / persistence (storage engine).
• inject additional layers

Specifically this enables the following:

• Allow custom Search/* handler: Solr provided, elastic search possible
• Allow custom Criterion / Field Converter / Sort Clauses
• Allow us to disconnect permission handling form domain logic
  • Allows us to cleanup API in regards to permission (remove sudo, some params, public but internal functions)
  • Allows us to introduce API caching to improve Repository performance
