About the specification source
The DITA specification is authored in DITA. It is a complex document that uses many DITA features, including key references (keyrefs), content references (conrefs), and controlled values set in a subject scheme map.
The source files for the DITA specification are managed in a GitHub repository that is maintained by OASIS; they also can be downloaded from OASIS.
The DITA Technical Committee used the following applications to work with the DITA source:
- Antenna House Formatter
 - DITA Open Toolkit
 - Congility Content Server
 - Oxygen Content Fusion
 - Oxygen XML Editor
 - XMetaL Author Enterprise
