xCMIS: Open Source CMIS Implementation

eXo Platform Releases Open Source CMIS Implementation

New xCMIS Server Expands Open Source Choice in the Market, Optimized for GateIn Project

San Francisco, California, USA. February 11, 2010.

eXo Platform today introduced xCMIS, an open source implementation of the Content Management Interoperability Services (CMIS) specification. Fully compliant with the latest CMIS 1.0 — cd06 specification, xCMIS supports eXo's standards-based Java content repository (JCR) and works with third-party CMIS clients as well as a new eXo CMIS client based on Google Web Toolkit (GWT). The xCMIS server is being released as open source code under the LGPL at

eXo's new GWT-based CMIS client offers the flexibility of building both standalone web applications and Google gadgets. Applications or gadgets created with this framework can be loaded from a remote location or integrated into a portal such as GateIn (, the portal runtime co-developed by eXo and JBoss. The eXo CMIS client comes bundled in the xCMIS download, and will be accessible as a remote gadget leveraging GWT client libraries at

Created by OASIS to enable greater interoperability of enterprise content management (ECM) systems, CMIS provides a common interface using either AtomPub or Web Services to enable content sharing across different content management systems. Applications are no longer tied to any one specific content repository, so developers can write new applications without concern for the development platform or language dependencies on any single content system. With xCMIS, eXo joins the rank of ECM providers that have rallied behind CMIS.

"eXo was founded on open standards, which remain core to our DNA," said Benjamin Mestrallet, CEO of eXo Platform. "We started with the industry's first Java portlet container, one of the first open source Java content repositories, one of the first enterprise OpenSocial implementations and now one of the most complete CMIS implementations available. In line with this commitment to open standards, we're making xCMIS widely available as open source to ensure that any developer can have access to a first-class CMIS server with which to write their applications."

The xCMIS server is available as a community beta release today with a production-ready version planned when the final CMIS 1.0 spec is ratified. Commercial support for xCMIS will be included in the next enterprise version of the eXo Platform, version 3.0, which will be based on GateIn.

eXo will be hosting a free one-hour webinar about xCMIS on 24 February 2010. The webinar will include an overview of the CMIS specification, an introduction to the features of xCMIS and a step-by-step tutorial for creating gadgets that can make newly unlocked content even more useful.
