The publication <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt digital</hi> is created in <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum</hi>. The <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.ediarum.org/">digital working environment <hi rendition="#i">ediarum</hi></ref> is a solution developed since 2012 by the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://www.bbaw.de/telota">DH initiative TELOTA</ref>, that allows scholars to edit transcriptions of manuscripts, comments, and index entries in TEI-compliant XML, add a critical apparatus and notes, and then publish them on the web and as PDFs (<bibl xmlns="http://www.tei-c.org/ns/1.0" corresp="https://edition-humboldt.de/ZFPTSUNP">Dumont/Fechner 2014</bibl>). <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">Ediarum</hi> consists of several software modules. For the input and editing of data, edition humboldt digital uses the module <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.BASE.edit</hi>, which - as is usual with ediarum - is supplemented by a project-specific module <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.AVHR.edit</hi> for the edition humboldt digital. The module ediarum.REGISTER.edit is used to create and maintain the index entries. An exception is the bibliography, which is maintained in the literature management software Zotero. For this, <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">ediarum.DB</hi> offers an interface for synchronization.
