The dimensions — seven kinds of thing

The dimensions are grouped by type of operation, not by number. That grouping records the project's first finding about itself: ten of its twelve original dimensions turned out to be the same operation — extract, enumerate, tabulate — however varied their subjects looked. What a dimension does is the real difference between them. The same studies open from the register side at by register, and from the day's side at by episode.

Where the project stands: 9 built · 0 building · 6 planned · 1 dropped, of 16 dimensions. The build is finished; what stays planned stays planned by design, and this index shows each status honestly. The counts are of whole dimensions; 22 built register artifacts — gold in the grid below — sit ahead of that count.

There is another way in. Every dimension has up to four output registers, and you can enter the grid by register instead — every document, every presentation, every diagram.

Type I — Inventory

The operation: extract a category, enumerate, tabulate. The output is a reference. No more than three Type-I dimensions are built (anchor A11).

• The Object Museum — built · the object (~30) — position hour by hour, hand to hand
• The Women's Dublin — built · the woman (~15) — income, mobility, interiority; and how she enters the text
• The Governed City — built · the instrument of rule — Castle, police, barracks, informers, courts, language
• The Ledger — planned · the transaction
• The Body's Accounts — planned · the passage in or out, across nineteen hours
• The Dead — planned · the deceased, and the mode of each return
• The Songbook — planned · the song, the singer, and what the words do against the scene
• The Eighteen Styles — planned · the episode's technique and what it costs the reader
• The Apparatus — planned · Linati vs Gilbert, and the book with the grid switched off

Type II — Inversion

The operation: map the absence rather than the presence. The output is a reference of negatives.

• The Concordance of Failures — built · the place where Joyce refuses Homer — one column, eighteen rows

Type III — Case study

The operation: primary evidence from one reader. The output is an argument from data.

• The Difficulty Curve — built · the logged question — 290 extracted, 245 placed against episodes, page-anchored across sixteen exchanges of an accompanied first read

Type IV — Comparative

The operation: the book against other versions of itself. The output is a parallel text.

• Ulysses in Turkish — dropped · what it would have been: the crux — a comparison of translations of the book, set against the English on common cruxes
• Four Odysseys — built · the work, measured on two axes — fidelity to Homer's plot and genre, and interior orientation (Homer · Wilson 2017 · Joyce 1922) — with reports of Nolan 2026 held to a separately-denominated register, off both axes

Type V — Model

The operation: a constructed system you operate. The output is a thing that runs.

• The Constraint Model — built · the constraint — a graph of eighteen places from the itinerary, a clock running from eight, two purses in pre-decimal coin, and the obligations of two men

Type VI — Made object

The operation: a work, not a document about a work. The output is art.

• The Atlas of One Day — built · the panel — eighteen, one per episode, each carrying three slots in one fixed order and without a caption: an object slot holding a thing of the KIND the book names, the place the episode happens in, and a period document; meaning made by arrangement rather than by argument. Corrected 25 July 2026: this field named two layers where the source manifest has always carried three, so the site's own definition of a panel undercounted it by one (anchor A4). Corrected again 27 July 2026, in the other direction. It read "each juxtaposing three layers", present tense, and on the day it was written no panel juxtaposed three — ten carried two and eight carried one. A slot is not a picture. The field now describes the FORM, which is fixed at three slots, and the coverage is derived onto the artifact itself and into docs/STATE.md rather than asserted here, because how many slots hold a picture changes with every acquisition (L-22). Found by the joint session of 27 July. And the first slot is named correctly as of 27 July 2026, on the author's ruling: it read "an object", and what those seventeen slots hold is a thing of the same KIND as the object the book names — a letter for a letter, a sovereign for a sum of money. In a caption-free panel position asserts identity, so a slot called an object was claiming to be Mr Deasy's own letter. The pictures did not change; the description did (catch C-84 found it, catch C-92 applied the ruling).

Type VII — Instrument

The operation: a tool a reader uses on their own read. The output is a tool the reader keeps — nothing is collected.

• The Reading Log — built · the reading session — date, pages, where the reader stalled, what they wanted to ask, what unblocked them, and whether they stopped

A type is a classification, not an address. A dimension may be reclassified, and a planned dimension may be dropped, and no link breaks. The working document holds the full reasoning behind the seven types.
