The interface itself, i.e. the XQL, XSLT and JS scripts as well as CSS and other files, is currently not publicly versioned. However, it is versioned and kept in a git for development purposes. For the future, it is also planned to store each version of the digital edition (as a user interface) additionally in the <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://webarchive.bbaw.de/">web archive of the BBAW</ref> and to keep it there. The <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt digital</hi> is currently being technically prepared so that it can be archived in the best possible way.
