This source edition is a model project for testing and improving existing digital infrastructures. The project takes advantage of open source solutions and integrates common standard formats for digital editions. It also includes long-term archiving for MODS (catalog data), METS (digitized content), TEI P5 (text tagging of the transcripts and translations), URN or DOI (persistent identification), GND-Beacon files, and the MyCoRe viewer. It combines these with a user-friendly presentation in a common open source CMS (content management system). Digitization has been carried out following the practical guidelines “Digitalisierung” established by the Deutsche Forschungsgemeinschaft (DFG). All digital files, TEI files, and metadata are also stored for long-term archiving as a METS Container in an instance of the MyCoRe repository. The digitized records (facsimiles), transcripts (full text), and translations are embedded into a visually appealing frontend by means of a viewer plug-in for METS Container, which is connected to the repository by an OAI interface.
