You'll get a lot more out of the box if replacing at the repository level instead. You don't need to apply options or analyze query strings.

And most resource definition callbacks are handled.

That's because the built-in resource service translates all JSON:API aspects of the request into a database-agnostic data structure called `QueryLayer`.

Now the hard part for you becomes reading that data structure and producing data access calls from that.

If your data store provides a LINQ provider, you may reuse most of [QueryableBuilder](https://github.com/json-api-dotnet/JsonApiDotNetCore/blob/master/src/JsonApiDotNetCore/Queries/Internal/QueryableBuilding/QueryableBuilder.cs),

If your data store provides a LINQ provider, you can probably reuse [QueryableBuilder](https://github.com/json-api-dotnet/JsonApiDotNetCore/blob/master/src/JsonApiDotNetCore/Queries/QueryableBuilding/QueryableBuilder.cs),

which drives the translation into [System.Linq.Expressions](https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/expression-trees/).

Note however, that it also produces calls to `.Include("")`, which is an Entity Framework Core-specific extension method, so you'll likely need to prevent that from happening.

We use a similar approach for accessing [MongoDB](https://github.com/json-api-dotnet/JsonApiDotNetCore.MongoDb/blob/674889e037334e3f376550178ce12d0842d7560c/src/JsonApiDotNetCore.MongoDb/Queries/Internal/QueryableBuilding/MongoQueryableBuilder.cs).

For [MongoDB](https://github.com/json-api-dotnet/JsonApiDotNetCore.MongoDb/blob/master/src/JsonApiDotNetCore.MongoDb/Repositories/MongoRepository.cs), we use the MongoDB LINQ provider.

If there's no LINQ provider available, the example [here](https://github.com/json-api-dotnet/JsonApiDotNetCore/blob/master/src/Examples/DapperExample/Repositories/DapperRepository.cs) may be of help,
