The valuable lexicographical data mentioned before were meant to be made sustainable available on the internet. To this end, they had to be transferred into an existing infrastructure, the research infrastructure for lexicography available at the Austrian Centre of Digital Humanities (ACDH) of the Austrian Academy of Sciences. The Academy has a long-standing tradition in eLexicography to which several departments contributed over more than hundreds of years. Most recently, the ACDH hosts a research group on eLexicography, the lexicography laboratory (1.1.2015-), to support, coordinate and methodically explore experimental scholarship in the fields of lexicography. <lb xmlns="http://www.tei-c.org/ns/1.0" />The emerging infrastructure is made up of several components: (1) an editor, (2) a formalised encoding framework, (3) a depositing back end and (4) a publishing system, all of which have been integrated into one system. An important keyword in this endeavour has been modularisation, the system not being one single piece of software but a number of complementary components that interlock neatly through clearly defined interfaces.
