Segue was a curricular content management system designed for teaching, learning and research. It was essentially a synthesis of wikis, blogs and traditional content management systems. Segue borrowed from the blogosphere the notion of multiple entries or posts on a page, each with their own URL and attached comments. Segue then provided a version history of each post and allowed users to link between posts using "wiki" markup. When a "wiki link" is created to content that does not exist, a "create node" link is displayed that allows users to add that content. Finally, like many content management systems, Segue allowed users to organize their sites hierarchically and control access by specifying who can discuss, edit or delete any existing content as well as who could add new content.
