DAML UML Enhanced Tool (DUET)

From the website: "DUET provides a UML visualization and authoring environment for DAML. Core DAML concepts are being mapped into UML through a UML profile for DAML. DUET will have the capability to work with multiple ontologies simultaneously, and to interact with other DAML services to interactively build ontologies. It's intended users are database designers and systems engineers, many of who all ready have a good understanding of UML and object-oriented modeling, which they can leverage to apply DAML to their systems."
