Subclass of:

• crm:E28 Conceptual Object

Superclass of:

• crm:E56 Language
• crm:E57 Material
• crm:E58 Measurement Unit

Scope note:

This class comprises concepts denoted by terms from thesauri and controlled vocabularies used to characterize and classify instances of CRM classes. Instances of E55 Type represent concepts in contrast to instances of E41 Appellation which are used to name instances of CRM classes.

E55 Type is the CRM’s interface to domain specific ontologies and thesauri. These can be represented in the CRM as subclasses of E55 Type, forming hierarchies of terms, i.e. instances of E55 Type linked via P127 has broader term (has narrower term). Such hierarchies may be extended with additional properties.

Examples:

weight, length, depth [types of E54]

portrait, sketch, animation [types of E38]

French, English, German [E56]

excellent, good, poor [types of E3]

Ford Model T, chop stick [types of E22]

cave, doline, scratch [types of E26]

poem, short story [types of E33]
