From the e-mailing:

"The SharePartXXL Taxonomy Extension for Microsoft SharePoint enables documents and list items in a SharePoint-based portal to be organized cross-site as part of a connected content network and knowledge model. SharePoint items are associated by category using one or more custom taxonomies. So users can organize documents and other portal contents in the way that they think and work. With that extension
the SharePoint portal really can become a place to share knowledge as well as content:"
