Barcodes: Turning Loci Into Standardized Records

A single locus is a sentence. A barcode is what happens when many of those sentences get arranged into a standardized paragraph — a template where the role of every sentence is fixed in advance, so that any two barcodes can be compared field by field.

Why “barcode”

The name comes directly from the ubiquitous scannable barcodes on retail products. Both a UPC and a Locus barcode do the same underlying job: encode information about something into a universal, standardized structure that makes sorting and comparison possible across every instance of that structure, not just the one in front of you. The comparison is intentional, not just a naming convenience — comparing expressions across a barcode is what lets the model analyze how functions relate to each other, and comparing different barcodes is what lets it group similar entities together in the first place.

The Enterprise Barcode

The Enterprise Barcode was the first barcode Locus developed, and it’s common enough in the source material to sometimes just be called “the barcode” without qualification. It comprises twenty loci arranged across five fields — Enterprise, Intermediary, Customer, Co-Customer, and Customer of Customer — emphasizing demand-side attributes: how a customer actually interacts with and uses the enterprise’s product, not how the enterprise happened to make it. The barcode’s “story” always starts with the enterprise and adds information with each subsequent field; there’s deliberately no supplier field in the current design, though the source material notes a supply-sided barcode is a real, if harder, possibility for the future.

The Labor Barcode applies the same underlying logic to a single job rather than a company’s product line — far fewer fields, no markers, but the identical Constituent/Final Resource Locus machinery underneath.

Fields, levels, and markers

Every barcode is organized along two axes at once. A horizontal level describes a type of economic entity — agent, department, work group, final resource, constituent resource — stacked from resource loci at the bottom to agent loci at the top, reflecting how work groups actually nest inside each other. A vertical section describes a different economic agent’s relationship to the product. Where a level and a section intersect is a field — one cell, containing a locus and whatever markers apply to it. Markers themselves are natural-language tags layered on top of a locus, adding contextual information — like whether an agent is a business, consumer, or government — that the bare locus alone can’t convey.

“Functional Barcode” is another name for the Enterprise Barcode specifically, not a separate parent class covering Enterprise, Labor, and Summary Barcode as distinct instances. “Enterprise Barcode” is the standing term used throughout this vocabulary.
