The goal of this project is to connect architecture documentation and models for different purposes like traceability link recovery and identifying inconsistencies (e.g. missing or deviating elements). More information can be found at the research group's project site and at the home page.
To start, have a look at the Core framework as well as its Wiki.
ArDoCo is actively developed by researchers of the Modelling for Continuous Software Engineering (MCSE) group of KASTEL - Institute of Information Security and Dependability at the KIT.
