Datamapper is an ruby (MRI, YARV, JRuby) Object Relational Mapper (ORM) comparable to Sequel or ActiveRecord. Unlike it's comparables, datamapper is becoming increasingly data store agnostic. Not only can it be used to avoid writing sql, but is aiming to define a general language for object storage. This talk aims to present the recent developments in dm-core/next branch and what these changes have to offer developers working with multiple non relational data stores.
