I'm trying to use Simple Savant within my application, to use SimpleDB

I currently have (for example)

public class Person
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public DateTime DateOfBirth { get; set; }
}

To use this with Simple Savant, i'd have to put attributes above the class declaration, and property - [DomainName("Person")] above the class, and [ItemName] above the Id property.

I have all my entities in a seperate assembly. I also have my Data access classes an a seperate assembly, and a class factory selects, based on config, the IRepository (in this case, IRepository

I want to be able to use my existing simple class - without having attributes on the properties etc.. In case I switch out of simple db, to something else - then I only need to create a different implementation of IRepository.

Should I create a "DTO" type class to map the two together?

Is there a better way?
