The 13th Workshop on Ontology Design and Patterns was another edition of a workshop series covering issues related to quality in ontology design and ontology design patterns (ODPs) for data and knowledge engineering in Semantic Web. The increased attention to ODPs in recent years through their interaction with emerging trends of Semantic Web such as knowledge graphs can be attributed to their benefit for knowledge engineers and Semantic Web developers. Such benefits come in the form of direct links to requirements, reuse, guidance, and better communication. The workshop's aim was to provide an arena for discussing patterns, patternbased ontologies, systems, datasets, etc. but also to broaden the pattern community by developing its own “discourse” for discussing and describing relevant problems and their solutions. A recent development in the Semantic Web community is that the general idea of “pattern” has begun to appear in diferent but related forms, and at WOP 2022, we continued to include these new trends. WOP2022 was held as a half-day virtual event associated with the 21st International Semantic Web Conference (ISWC2022). The program included an inspiring keynote by Karl Hammar, paper presentations, and a plenary discussion. Altogether, WOP2022 received 8 high-quality submissions, of which 7 were accepted. We are very grateful to members of the Program Committee without whom the workshop would not have been possible, to our invited speaker, Karl Hammar, and also thank the organizers of the 21st International Semantic Web Conference for hosting WOP2022 at ISWC 2022. Finally, we thank all the authors for their submissions. Further information about WOP2022 can be found on the workshop's website http://ontologydesignpatterns.org/wiki/WOP: 2022.
