Although it has evolved since, the Apache Isis framework started out as an open source implementation of the naked objects pattern. Indeed, the generic user interfaces provided by Isis Wicket and Scimpi viewers just naked objects systems, providing a default generic representation of domain objects. The Restful Objects viewer is also a naked objects system; it's just that the representation is intended for machines rather than human beings.
If the idea of naked objects is of interest, then there are a couple of books on the topic that you might want to read.
Richard Pawson and Robert Matthews, Wiley 2002
This book describes the original ideas of Naked Objects. Although based on a very early version of the framework, it's still definitely worth a read (and beautifully produced).

Dan Haywood, Pragmatic Bookshelf 2009
This more recent book draws the parallel between domain-driven design and Naked Objects (4.0). In the spirit of the Pragmatic Bookshelf, it's a practical, hands-on sort of book, building up a case study as it goes and encouraging you to build your own app as you go.

The Restful Objects specification defines a set of RESTful resources, and corresponding JSON representations, for accessing and manipulating a domain object model.
This is a comprehensive specification, running to over 200 pages in length. It is implemented by Isis' Restful Objects viewer, and is also implemented by another (non-Apache) open source project, Naked Objects MVC.
