There is a need for visualization tool that allows users to more easily connect to primary sources of information. The idea is to allow users to see for themselves the primary sources of information that validate or justify the assertions made in RDF statements. This will allow users to directly and easily review the primary sources. VTLS has developed a tool that will allow staff to reify RDF assertions with links to the justifying artifact. Once all of the justifications have been established, they are presented via the Web in a graphical interface.
