An information integration system may include a set of integration services embodied on one or more server machines in a computing environment. The set of integration services may include connectors communicatively connected to disparate information systems. The connectors may be configured for integrating data stored in the disparate information systems utilizing a common model employed by the set of integration services. The common model may overlay, augment, integrate, or otherwise utilize a content management interoperability services data model and may include common property definitions and a common security model. The common security model may include permissions particularly defined for use by the set of integration services. These common property definitions and permissions may be uniquely defined and utilized by the information integration system.
