## Chapter 3. xCMIS project

xCMIS includes the client side frameworks for integrating content from different enterprise repositories, according to http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=cmis .

The project is to make joining Enterprise Content repositories simpler by offering CMIS ablity and exposing them to language-independent CMIS clients via the most convenient protocol.

xCMIS project:

- Is embedded, packaged as the J2EE Web archive (WAR) and prepared "download and go" Tomcat bundle.

- Has a live demo with the full-featured CMIS Expert client, which is accessible on the xcmis.org site and with prepared "download and go" Tomcat bundle (the client is accessible as the remote gadget).

- Is embedded in Platform to create the special xCMIS jcr repository and access it with any CMIS client.

- Tested with third-party CMIS clients, such as IBM CMIS Firefox Connector and CMIS Spaces Flex+AIR client. Either local repository (as described here) or http://xcmis.org/xcmis1/rest/cmisatom can be used as a CMIS repository's endpoint URL for these or other types of clients.

Benefits of xCMIS

- xCMIS is an open source, server side Java CMIS implementation, enabling to expose content in the existing content repositories according to the protocols defined in the CMIS specification.

- xCMIS will give developers a way to make their content repositories "pluggable" on the server side based on the internal Storage Provider Interface and additional protocol on-demand bindings.

- xCMIS will provide (several) CMIS client frameworks for repository-application and repository-repository interactions. The programming language and supported protocol can be selected by users. For example, the reasonable choice for using web applications, gadgets, and/or mashups is JavaScript or GWT over REST AtomPub, while for inter-repository exchange, it may be Java over Web Services, i.e. WSDL/SOAP.)

- Both the server and client sides of xCMIS are easily integrated in the eXo Platform 3.0 infrastructure. In particular, xCMIS exposes the eXo JCR content repository and provides a framework for building web applications and gadgets for the GateIn portal.
