At present the most common reference for Rusian genealogy is a nearly hundred-year-old article by N. de Baumgarten. The Rusian Genealogical Database provides a much needed update to this classic study, utilizing primary sources from throughout Europe, together with modern interpretations of those sources, to create a comprehensive reference tool. In addition to its utility as a reference, the Database can also serve as a resource for further research on the relationships among Riurikid family members, as well as their marriages, children, and even places of rule. This genealogy has been made more accessible through the use of extensible markup language (XML) technologies, which provide much of the power of traditional relational databases in a way that is well suited to representing both textual and tabular data. The combination of modern historical methodology with modern technology has created a tool that is easy to use, even when discussing the complex genealogy of the Riurikid family.
