We would like to invite internationally recognized experts on ontology engineering, as well as ontology practitioners and users to contribute by providing positive examples of good, interesting and elegant ontology designs – i.e., ‘beautiful ontologies’. There is no constraint on the chosen ontology, on its format, on the formalism in which it is implemented, on the domain it describes, on its creator(s) or even on its 'score' according to classical evaluation methods. However, each beautiful ontology article should clearly explain why, according to the author, the chosen ontology is interesting and how it contributes to the overall discussion on ontology quality.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">By gathering in this way different views on concrete examples, we hope to achieve a better understanding of quality ontology design, providing a concrete reference for less experienced ontology practitioners as well as an ethnographic basis for collecting best practices in ontology design. As such, this initiative relates directly to others in the domain, like the OntologyDesignPatterns.org portal, and might generate direct contributions to them.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><b>Submission</b></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><b></b><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">We seek submissions of articles discussing either an existing ontology as a whole, an ontology module, an ontology design pattern or even a particular characteristic of an ontology (including the way it has been used or applied).
