Mongomatic: A New Ruby MongoDB Library Hits The Scene
Mongomatic is a Ruby library that lets you easily model your MongoDB documents in your applications.
The primary design goals of Mongomatic are simplicity and adherence to MongoDB conventions. Mongomatic is not an ActiveRecord clone and has been designed to fit nicely with the document-oriented nature of MongoDB.
Features include cursors, hash access to your document and embedded documents, validations, callbacks and conventions for creating indexes and relationships.
I haven't given it a try myself yet, but Ben's done a good job of presenting it, along with example code, so check it out if MongoDB is your bag.
