The Project Type field may be superfluous as the type of project could be determined strictly by the Project Parent field, and additional Project topics would be created called Govt Oversight and Issue Oversight that would be parents to any projects in those categories. To determine the classification of any given project, however, it is necessary to follow all parent links until the ultimate parent is found. Although this design is possible, it makes such determination and qualified searches much more difficult given the flat-search method used by TWiki. An enhancement to TWiki would be linked topic facility, which is currently not available. Therefore, we will strive to keep the tree of projects as flat as possible, and rely on the Parent-Child relationship only as a means to assist the user to find related projects.
