Subclass of:

• crmsci:S10 Material Substantial
• crm:E72 Legal Object

Superclass of:

• frbroo:F7 Object
• crmsci:S20 Physical Feature
• sdh:C49 Amount of Matter
• sdh:C9 Intentional Entity
• crm:E19 Physical Object
• crm:E24 Physical Man-Made Thing
• crm:E26 Physical Feature

Scope note:

This class comprises all persistent physical items with a relatively stable form, man-made or natural.

Depending on the existence of natural boundaries of such things, the CRM distinguishes the instances of E19 Physical Object from instances of E26 Physical Feature, such as holes, rivers, pieces of land etc. Most instances of E19 Physical Object can be moved (if not too heavy), whereas features are integral to the surrounding matter.

The CRM is generally not concerned with amounts of matter in fluid or gaseous states.

Examples:

the Cullinan Diamond (E19)

the cave “Ideon Andron” in Crete (E26)

the Mona Lisa (E22)

Context notes:

In a foundational perspective, this class is equivalent to the Physical Endurant class in DOLCE, cf. Stefano Borgo et al., ‘DOLCE: A Descriptive Ontology for Linguistic and Cognitive Engineering’, Applied Ontology, 2022, 1–25 <https://doi.org/10.3233/AO-210259>. It is therefore to be considered as a sibling and disjoint class of the crm:E28 Conceptual Object class, equivalent to Non-physical Endurant in DOLCE.
