Subclass of:

• crm:E1 CRM Entity

Superclass of:

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

Scope note:

Time spans, places, dimensions, etc. are all regions in an abstract, conventionally defined reference system for measuring time, space, colors, ranges of values, etc. This view is consistent with DOLCE and the top-level category 'abstract' introduced by this foundational ontology (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)
