On his site Paul Jones has posted about the release of a stable version of the Atlat.Query package that provides "a data mapper implementation for your persistence model" versus the domain models like many other frameworks use.

I am happy to announce that Atlas.Query is now stable and ready for production use! Installaton is as easy as composer require atlas/query ~1.0.

In the post he includes some examples of the library in use, howing how to create a connection, fine-tune the PDO settings, and perform select and insert queries. You can find out more about the library, its goals and the features it provides in the project documentation.
