1.1 added rdfs:isDefinedBy for all named entities
It is possible to make asser tions about e.g., categories, types, roles, which are typically considered at the meta-level of an ontology. Instances of Concept reify such elements, which are therefore put in the ordinary domain of an ontology. It is not possible to parametrize the classiﬁcation over different dimensions e.g., time, space, etc.
Mac OSX 10.5 is classiﬁed as an an operating system in the Fujitsu-Siemens product catalog.
The classification content ontology design pattern. This CP represents the realtions between concepts e.g., roles, task, and entities to which concepts are assigned to e.g., person, activities. The CP is extracted form DOLCE Ultra Lite ontology.
To represent the relations between concepts (roles, task, parameters) and entities (person, events, values), which concepts can be assigned to. To formalize the application (e.g. tagging) of informal knowledge organization systems such as lexica, thesauri, subject directories, folksonomies, etc., where concepts are ﬁrst-order elements.
Typically combined with descriptionandsituation. It is specialized by cat:objectrole. The n-ary classiﬁcation CP provides an alternative to this if classiﬁcation has to be qualiﬁed over different dimensions.
What concept is assigned to this entity? Which category does this entity belong to?
classifies
classifica
