IBM has expanded set of social software tools and capabilities for Lotus Connections enterprise collaboration by adding features such as micro-blogging and web-based file sharing.

The Lotus Connections 2.5 also includes Wiki service that allows users to create, view, edit and contribute to content that is uploaded to a collaborative website. It has automatic versioning and a ‘show changes’ view, enabling users to view the latest versions and edits, the company said.

According to IBM, the Profiles service is enhanced with a micro-blogging feature that allows users to post status updates on tasks they are working on. It comes with a new message board feature that offers a place on a user’s profile page where colleagues can post messages and comment on status updates. The combination of the message board and micro-blogging capabilities provides an easy way for users to maintain active connections.

The company said that the new web-based file sharing library allows users to upload and securely share content such as presentations and documents. It includes social software features such as tagging, ratings, recommendations and the ability to comment on content.

The company has also expanded mobile capabilities with support for iPhone and Nokia S60 devices. It provides access to Lotus Connections Profiles, Activities and Blog services. In addition, the new release offers enhancements to existing services including Home Page, Blogs, Bookmarks and Activities offered in the previous version of the platform.

Jeff Schick, vice president of social software at IBM, said: With Lotus Connections, we have merged document sharing and social networking capabilities to create a comprehensive collaboration platform for businesses. Today’s announcement showcases how IBM is delivering easy access to a company’s two most valuable assets – people and information.
