DTA 'Base Format' (DTABf): Schema and Documentation
Version 1.1.0

Introduction and HowTo

These are the source files of the DTA 'Base Format' schema and documentation (version 1.1.0). The DTA 'Base Format' (DTABf) is a TEI format for the annotation of digitized historical texts. It is the annotation basis for all texts published on the Deutsches Textarchiv (DTA) platform [1].

To explore the DTABf documentation see the official website. The DTABf documentation also contains information on how to access the RNG schemas and how to use them.

For elaborate information on the purpose of the format and constraints for its further development see the DTABf Guiding Principles.

This repository also contains instructions on the conversion of the DTABf-documentation source files in DITA to Webhelp responsive output as well as derivatives for ODD chaining.

Third Party Copyright Information

The DTABf is based on the P5 guidelines of the Text Encoding Initiative (TEI) [2]. The TEI P5 guidelines were only reduced or tightened, never extended. Thus, the DTABf is fully compliant to TEI P5.

The TEI P5 guidelines and adjacent software are distributed under the Creative Commons Attribution 3.0 Unported License ( and the BSD 2-Clause license (

The DTABf documentation is based on the XML documentation architecture DITA (Darwin Information Typing Architecture) [3]. It has been automatically converted from the original HTML files to DITA. All further works on the documentation were carried out within the oXygen XML Editor [4]. DITA support within the oXygen XML Editor is based on the DITA Open Toolkit [5]. The "Webhelp mobile" output version published on is furthermore based on a respective DITA plugin provided by oXygen [6].
