content: OWL 2 Has New Options; Useful to SKOS, Too It is not unusual to want to treat things either as a class or an instance in an ontology, depending on context. Among other aspects, this is known as metamodeling and it can be accomplished in a number of ways. However, the newest version of the Web Ontology Language, OWL 2, provides a neat trick for doing this called "punning". Why one would want to metamodel, how to specify it in an ontology, and why the OWL 2 approach is helpful are described in this post [1]. Why Metamodel? Lightweight, domain ontologies have been the focus of this ontology series. Domain ontologies are the "world views" by which organizations, communities or enterprises describe the concepts in their domain, the relationships between those concepts, and the instances or individuals that are the actual things that populate that structure. Thus, domain ontologies are the basic bread-and-butter descriptive structures for real-world applications of ontologies. These lightweight, domain ontologies often have a hierarchical structure for which SKOS (Simple Knowledge Organization System) is a recommended starting ontology [2] (see best practices recommendations). A subject concept reference ontology such as UMBEL (Upper Mapping and Binding Exchange Layer) [3], which we also recommend, also has a similar structure and a heavy reliance on SKOS in its vocabulary. Because of these structural similarities, ontologies that use SKOS or UMBEL are therefore good candidates for using metamodeling techniques. To better understand why we should metamodel, let's look at a couple of examples, both of which combine organizing categories of things and then describing or characterizing those things. This dual need is common to most domains [4]. For the first example, let's take a categorization of apes as a kind of mammal, which is then a kind of animal. In these cases, ape is a class, which relates to other classes, and apes may also have members, be they particular kinds o…
