The project Beta maṣāḥǝft: Manuscripts of Ethiopia and Eritrea (Schriftkultur des christlichen Äthiopiens: eine multimediale Forschungsumgebung) is a long-term project that aims at creating a digital research environment for the study of the Ethiopian and Eritrean manuscript culture. Digital catalogue entries of manuscripts, text editions, and other relevant records (e.g. certain persons) are encoded in TEI XML. One of the important outcomes of the project is a systematic description of the literary and non-literary texts attested in the Ethiopian and Eritrean manuscript culture. That implies not only encoding, but the establishing of semantically meaningful relations between the texts. The poster is dedicated to the Ethiopic Psalter of the Virgin und to a strategic proposal of encoding of its structure in TEI XML.
