The DL workshop is the major annual event of the Description Logic research community. It is the forum at which those interested in description logics, both from academia and industry, meet to discuss ideas, share information and compare experiences.

The 28th Description Logics Workshop will be held in Athens, from June 7th to June 10th, 2015.

DL2015 will be collocated with the 4th OWL Reasoner Evaluation (ORE) workshop
