go language that implements a rich and well tested selection of features under a very simple API following standard Go idioms.
Note that the "original" mgo driver ( https://github.com/go-mgo/mgo) developed by Gustavo Niemeyer has gone dark (unmaintained). Even the author himself recommends to use the community supported fork https://github.com/globalsign/mgo which is in much better shape.
