The International Workshop on Description Logics is the main annual event of the Description Logic research community. It is the forum at which those interested in description logics, from both academia and industry, meet to discuss ideas, share information, and compare experiences. The workshop explicitly welcomes submissions from researchers that are new to the area and provides quality feedback via peer-reviewing, while at the same time being of an inclusive nature with a very high acceptance rate. There are only informal (electronic) proceedings and inclusion of a paper there is not supposed to preclude its publication at conferences. Further information can be found on the DL Web pages at http://dl.kr.org/. This volume contains the papers presented at the 29th International Workshop on Description Logics (DL 2016) held on April 21-24, 2016 in Cape Town, South Africa. Every submission to the workshop received three reviews, provided by 42 PC members and 13 additional external reviewers. Overall, the committee decided to accept 30 full papers and 12 extended abstracts. The contents of these papers were presented in 18 long talks of 25 minutes each, 22 regular talks of 20 minutes, and two status talks of 10 minutes. The program also included three invited talks by Diego Calvanese, Birte Glimm, and Dan Suciu, as well as a joint session with NMR 2016 with a keynote by Laura Giordano. We take this opportunity to thank all the PC members for their invaluable e ort, providing helpful and informative reviews for all the submissions on time. The organization and reviewing process was simpli ed by the tools provided by EasyChair. Paolo Felli designed and maintained the web pages, and kept up with our continuous requests for changes; he deserves praising for all his great work. The local organizers Thomas Meyer and Arina Britz were also of great support during this phase. Finally, this workshop would not be possible without the submissions and participation of all the people that make DL such an interesting community. We are also very grateful to the Foundation for Principles of Knowledge Representation and Reasoning (KR Inc.) and the European Coordinating Committee for AI (ECCAI) for their nancial support.
