Day Software (SWX:DAYN)(OTC:DYIHY) announced the availability of Communique 4, a native JCR (JSR 170) standard compliant enterprise content management solution. Communique 4 decouples the content management application from the underlying repository. Applications developed that leverage the API can run on any JSR 170 compliant repository. Communique 4 ships with and runs natively on Day’s java content repository, Content Repository Extreme (CRX). Communique 4 provides an easy transition from older releases. Existing Communique projects can be migrated “in place” with help of an update installer, leaving the existing deployments and architecture intact. New projects can readily use the standardized API and can benefit from the new technology. Communique 4 will run as a Servlet inside its own Servlet container or inside J2EE application servers.
