About physical entities

A physical entity is a materially existing object or substance that occupies space, has mass, and can be directly observed or measured, independent of linguistic or conceptual designation.
  • A physical entity may be natural or manufactured, discrete or aggregate, and movable or fixed.
  • A physical entity may be referred to by one or more names or terms, but the entity exists independently of those designations.
  • Physical entities may have attributes such as composition, form, dimensions, and function.
  • Physical entities may participate in part–whole, containment, or functional relationships with other physical entities.
This definition is consistent with ISO 704 and ISO 1087-1 terminology principles and aligns with ontological distinctions used in knowledge organisation systems, product classification schemes, and scientific taxonomies.

Distinction or terms from related entities

  • Physical entity vs concept: a physical entity is a material thing; a concept is an abstract unit of knowledge.
  • Physical entity vs term: a physical entity exists in the physical world; a term is a linguistic designation.
  • Physical entity vs event: a physical entity endures through time; an event occurs in time.

Adding a list into a document

When writing, a smart list of names can be generated from the terminology records that you have used in your document,
  1. A smart list will produce a list of all names found in your document across all sections
  2. See Style Guide / Terminology for editing the format of smart lists

Tips

  • Create different collections for easy maintenance, exporting, or sharing
  • We do not produce a list of work items, quotes, paraphrase, text blocks or websites as these are generally not required when writing documents.
  • You can export any collection in full directly from the collection record
  • If an abbreviation has been added in multiple places and needs updating, you can do so by editing the record and it will automatically update all instances
