SBVR11 — SBVR recognizes the notion of "property" in Clause 11.1.5 in "is-property-of", but never defines the concept directly

SBVR recognizes the notion of "property" in Clause 11.1.5 in "is-property-of", but never defines the concept directly. This omission should be corrected because "property" is a term used naturally by business people and business analysts. SBVR should own up to any term used commonly in the real world to form concepts and organize vocabulary.

Resolution:

Add the term "property" to Clause 11, defined as:

Property: thing playing a role in a fact wherein the thing is perceived as being closely held by or descriptive of the thing playing the other role in the fact

Dictionary Basis: a quality or trait belonging to a person or thing; [MWUD property]

Necessity: The fact must be for a binary fact type.

Example: In 'George was born on 22 February 1732', '22 Feb 1732' plays the role "birthdate", but "birth date" is a property of the person 'George'. The role has a range (date); the property has an owner (person).

Example: "ceiling" denotes a property of a room and a property of an aircraft, two different properties of two distinct things

An entry defining ‘property’ is needed to avoid misunderstanding and misinterpreting the signifier “property” as it is used in SBVR.
This is especially important because the SBVR meaning of “property” is different from the meaning of “property” and “attribute” is used in UML, E/R and other data/structure models
