Ontologies,ed understanding nor does it model the whole of the domain (Fig. .). It is widely stated that, while an ontology uses an open-world assumption, a model uses a closed-world assumption (e.g. Aßmann et al. 2006; Atkinson et al. 2006) although some ontologies are based on a closed-world assumption (e.g. Wang et al. 2006).

Linking Models, Metamodels, Ontologies and Modelling Languages, This is named, variously, meta-ontology, ontology specification language, foundational ontology or higher level ontology (see Fig. . and previous discussion). Such a language provides reasoning support not possible in software modelling languages such as UML or ER, which many researchers are tempted to use and/or extend for this purpose.

Metamodels,“a metamodel makes statements about what can be expressed in the valid models of a certain modelling language”. It should be stressed that the abstraction needed here is the F-abs kind of abstraction since it creates type rather than token models.
