[Discuss] Change of implementation for SubmodelRepositoryServiceProvider

[bjoernhoeper]

Currently the Creation of Submodels in the SubmodelRepositoryServiceProvider uses an extension method on the Submodel itself to create the Service Provider for that Submodel. But I consider the creation of the Service Provider the task of the SubmodelRepositoryServiceProvider and not one of the submodel.
Furthermore at the moment you could not inject another implementation into the SubmodelRepositoryServiceProvider that would allow a decision about which implementation to use. So the implementation for the service provideer is fixed then.

So my proposal is the following:

• Change the implemntation so that a Factory for service providers gets injected via DI
• The service provider is created using the injected factory
• The default implementation for the factory is the same realisation as currently with the extension method

This way the old behaviour is preserved and the adpatability is enhanced.

@constantinziesche Is there anything that stands against this approach?
