The long-term project funded by the NRW Academy of Sciences and Arts and the Union of German Academies at the University of Bonn explores the script and language of the Classic Maya culture. It aims to document Maya hieroglyphic inscriptions in a database and to catalog the hieroglyphic language in a digital dictionary. Sources such as literature, archives, and photo collections are researched, processed in the virtual research environment TextGrid, and published online. Information and images of inscriptions are stored in an object database and in the "Maya Image Archive," an open-access repository containing over 15,000 images, freely accessible to users.
