Subclass of:

• crm:E1 CRM Entity

Superclass of:

• crm:E54 Dimension
• crm:E52 Time-Span
• crm:E53 Place
• crm:E92 Spacetime Volume

Scope note:

This class comprises positions or regions in an abstract, conceptual space defined by a conventionally defined reference system, such as for measuring time, space, colors, ranges of values, etc. As such, the classes crm:E52 Time-span, crm:E53 Place, crm:E54 Dimension are all abstract regions in the sense of indicating a region or position in a reference system (a date in a calendar, geocoordinates, a value in a measuring system).
This view is consistent with the top-level category 'Abstract' and the notion of 'Region' introduced by the foundational ontology DOLCE (Gangemi 2002).

Examples:

Switzerland's bounding box in 2023 (instance of crm:E53 Place) as defined using the WGS 84 coordinate system (minLon: 5.967,  minLat: 45.15, maxLon: 12.467, maxLat: 52.883)

The color red "ff0000" in the Hex Color Code.
