** This is a large (30" x 40") Visio diagram suitable for hanging, and has all the formal definitions and comments that describe each concept. If you have our e6tOWL Tool (described here), you can generate the OWL directly from this diagram; otherwise, you can use it for documentation. Click here for a .pdf version of the full-sized diagram.*** This is a smaller (11" x 17") "placemat" that includes only the names of the concepts. We find it is useful once you know what all the concepts are and you only need to remember the names.
