SADE, an acronym for «Scalable Architecture for Digital Editions», is a software package that 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). Since 2012 a larger developer community has constantly been working on this software, which was originally 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 project TextGrid).

The software is based on the XML database eXist-db and its up to date version itself is a customization. It was developed for the TextGrid infrastructure. Over the years a few components became obsolete, so the current version is a completely rewritten one.


For a full overview see SADE's feature list.


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.
