We've released a small code collection that enables institutional repositories running on EPrints to easily add tagging, bookmarking, and related article linking to their sites.Tagging
The TaggingTool works by connecting the repository content to either Connotea, del.icio.us, or any service based on Connotea Code. It shows tags that have been used on repository items, allows users to save the item in their own Connotea or del.icio.us accounts, and shows links to related articles.
The tool is quick and easy to install, and requires only minimal changes to an existing EPrints repository. If you're a user of a repository and would like to experiment with the TaggingTool, point your administrator at the summary of its features.
