Interpretations have differed over what geographic area the term "Bagibaria" refers to. Some scholars have related it to "Babia Góra" near the river Vistula and Kraków in Lesser Poland, but it is more commonly considered to be a reference to Bavaria. Tibor Živković notes that this term can come from the Latin name of Bavaria ("Bagoaria" or, less probably, "Baioaria") and, therefore, the source of this information for the "DAI" could be of West European origin (possibly by Anastasius Bibliothecarius from Rome).
