2008 - Open Text bets on Enterprise 2.0. Box is in panic

Open Text
In its new version of the ECM system, which Open Text claims to be Enterprise 2.0 solution, the company offers the advanced features for collaboration and new social tools such as forums, blogs, tags. "To achieve maximum results, users need the Enterprise 2.0 tools for Content Management" - says Bill Forquer, Executive Vice President of Marketing at Open Text. "Many organizations use E-mail not as a part of ECM strategy. Their e-mail archives become uncontrolled. When implementing Enterprise 2.0 tools as a part of ECM, this will not happen. "The new version allows for example, to quickly create virtual workspaces that include web 2.0 tools such as forum and wiki. The company also announced the release of Livelink ECM Extended Collaboration, which is designed to simplify the introduction of Web 2.0 tools and applications for content management in the Enterprise.
