SharePoint 2010 added collaborative knowledge management and social networking features, and the Knowledge Management Suite aims to leverage those to "enable organizational intelligence in the enterprise." The suite focuses on content tagging, browsing, and discovery. It suggests a list of tags for a document based on established taxonomies and properties; it will also tag items automatically in the background. Collaborative tagging feeds into the Tag Navigation Web Part to make content discovery easier. The product is free (shareware) with some features limited; a single-server license is $1,899, and a year of maintenance and upgrade Software Assurance is $379.
