SADE, an acronym for «Scalable Architecture for Digital Editions», is a software application for the XML database eXist-db. It includes many components which are particularly suitable for developing and displaying a digital edition. It focuses on the presentation of XML documents that follow the guidelines of the Text Encoding Initiative (TEI).

TextGrid flavored SADE

This version is prepared to present data transferred via the TextGrid Laboratory. You can use the SADE Publish Tool Plug-In in the Lab for an easy data ingest. However, SADE can be run without using TextGrid at all.


SADE currently offers several features that help you set up a digital edition, e.g.:

and many more.

Since 2012 a larger developer community has constantly been working on this software, which has originally been developed at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) as part of the digitization initiative «The Electronic Life Of The Academy» (TELOTA). Contributors are among others the BBAW, the Austrian Academy of Sciences (OeAW; as part of the project CLARIN: Common Language Resources and Technology Infrastructure), the Max Planck Institute for the History of Science (MPI-WG), the Cologne Center for eHumanities (CCEH) and the Göttingen State and University Library (SUB; as part of the TextGrid project).

This TextGrid flavored SADE has been largely refactored, updated and further developed since 2015 by Göttingen State and University Library.
