Hi,
It was originally a fork from sails-orientdb but down the road has pretty much been re-written, tests added as well as features.
Underneath the covers it uses the great node.js driver Oriento. If you are building a SailsJS app it's quite obvious why you would use waterline-orientdb as it will give you plug 'n play access to OrientDB. If you are wondering if there is any point in using Waterline without SailsJS it has some nice features as:
- ORM with support for schemas / models / collections / associations;
- Validations;
- Multiple DB support through adapters.
I hope you find it useful!
