Diversified: The Locus “Div” Notation

Diversified (Div) is the notation for a range of admissible values within the Locus language, used whenever a single term needs to refer to more than one category, stage, or substage of activity or resource at once.

The full, properly staged form is DivDivDiv — representing category, stage, and substage together — but in practice it’s almost always abbreviated. If a company produces both C3i and C3ii resources, the barcode can refer to both at once as C3Div, eliding just the substage. If it produces both C3 and C4, that becomes CDiv, eliding stage and substage both. This is called aggregation: combining multiple specific values under one broader term rather than listing each one out.

Div isn’t only a stand-in for “we don’t know” — it can also express precision about scale. DivA and DivS denote different percentages of the semantically possible values being represented by the Div, letting the notation communicate not just that a range exists, but roughly how much of that range applies.
