General description

Name:	Classification
Submitted by:	User:ValentinaPresutti
Also Known As:
Intent:	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.
Domains:
Competency Questions:	What concept is assigned to this entity? Which category does this entity belong to?
Solution description:
Reusable OWL Building Block:	1 (788)
Consequences:	It is possible to make assertions 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.
Scenarios:	Mac OSX 10.5 is classified as an operating system in the Fujitsu-Siemens product catalog.
