Disclosed are mechanisms for sharing managed content through external systems. A sharing module publishes content in a share and metadata associated therewith to an external system. The share represents a folder or directory in a repository managed by an information system such as an enterprise content management system. The publication is made possible through application programming interface (API) calls handled by a first sharing module API, a repository API, a second sharing module API, and an external system API. These APIs together provide a one-to-one mapping of communications protocols used by the managed repository and the external system. The share in the managed repository and the share published to the external system are synced and any conflict between the two is detected and resolved. The shared content can be repatriated back to the managed repository and the shared version deleted from the external system.
