Mapping resources. Instances from the Carpathian Basin

Publishing provenance data on the Internet requires the integration of various resources, some of them easily accessible, some of them costly and protected by various copyrights. The work is based on thematic and archive maps, special fieldwork and research projects, data published in technical literature and stored in related databases. This paper will survey the accessible resources used for creating an “Atlas” of prehistoric raw materials for the Carpathian Basin, both commercial and public domain elements and will concentrate on the additional new value as well as problems of continuous maintenance. New developments in supporting reference collections at the Hungarian National Museum will be discussed as well.
