Dm-models is a project mainly written in Ruby, based on the View license.
Reusable standard models.
DataMapper Models is an effort to collect reusable and relatively stable model classes which can be integrated into other applications. This project was set up as a shared repository for utility models, educational code demonstrating particular DM features, and as a common basis for fixtures for DataMapper related projects. Please remember that contributions can either be in the form of a model class, or could be properties and functions contained within a mixin module.
