Alfresco, a provider of open source enterprise content management software, announced the immediate availability of a technology preview of the Alfresco open source content repository and portal integrations. An enterprise-scale content repository, JSR-168 portlets for managing and using content, and a Common Internet File System (CIFS) interface that provides Microsoft Windows file system compatibility are included in this release. Alfresco developed the system using the latest Java technologies, including JBoss Application Server 4.0, JBoss Portal 2.0, Spring 1.2, Hibernate 3.0, MyFaces 1.0, Lucene 1.4 and Java 1.5. The preview release of the Alfresco system provides enterprise content management capabilities in JSR-168 compatible portals and JBoss Portal 2.0. Adopting aspect-oriented programming as a foundation for adaptability, the Alfresco system uses the Spring Framework. To provide easy access to the content management repository for end users, Alfresco has included support for the Common Internet File System standard. CIFS allows users to tap into the Alfresco repository as though they were accessing a shared drive, permitting off-line synchronization, drive mounting and access from any application. A rules-based engine provides automatic versioning, classification and control eliminating the manual work associated with content management systems. The Alfresco system is available for immediate download. Source code, executables and a wiki are available from the web site. http://www.alfresco.org
