9 bundles · 19 layers · 21 findings · 57 questions
Identity, naming and classification How an agent tells one printer from another, and a printer from things that resemble it.
Recognition comes before every other claim. Without stable identity nothing else in the model can be trusted to be about the same thing twice.
Names and identifiers
The names this thing goes by and the identifiers that survive translation and time.
Preferred name, aliases and local names
Which name to use, which names mean the same thing, and which merely sound similar.
- What identifies and describes the name of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the name of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the name of a printer is known, and what must it refuse? action
Stable identifiers and external keys
Identifiers that keep pointing at this kind of thing across systems and languages.
- What identifies and describes an identifier for a printer, and in what units or vocabulary? definition
- Who or what asserted this about an identifier for a printer, by which method, and when was it true? provenance
- What may an agent decide or do once an identifier for a printer is known, and what must it refuse? action
Classification and granularity
Where a printer sits among kinds, and how finely a task needs to cut it.
Kind, parents and neighbouring kinds
The classes this thing belongs to and the ones it is next to.
- What identifies and describes the kind of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the kind of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the kind of a printer is known, and what must it refuse? action
Distinguishing features
What separates a printer from the things most often confused with it.
- What identifies and describes what distinguishes a printer, and in what units or vocabulary? definition
- Who or what asserted this about what distinguishes a printer, by which method, and when was it true? provenance
- What may an agent decide or do once what distinguishes a printer is known, and what must it refuse? action
Form, composition and condition What a printer is made of, what shape and size it takes, and what state it is in.
A physical thing can be measured, and a model that cannot record its measurements cannot support any decision that depends on them.
Form and dimensions
Shape, size, mass and the ranges these take across examples at handheld scale.
Measurable dimensions and their units
The quantities worth recording and the units they are recorded in.
- What identifies and describes the dimensions of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the dimensions of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the dimensions of a printer is known, and what must it refuse? action
Material and composition
Materials, parts and how they are put together.
Parts and materials
What a printer is built from and which parts are replaceable.
- What identifies and describes the composition of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the composition of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the composition of a printer is known, and what must it refuse? action
Condition and integrity
Wear, damage, health and the difference between working and broken.
Condition, damage and health
How the condition of a printer is judged and by whom.
- What identifies and describes the condition of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the condition of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the condition of a printer is known, and what must it refuse? action
Place and movement Where a printer is, how it got there and where it may go (portable).
A thing that can move needs its position recorded with a time, or every later claim about it is about a place it has left.
Location and placement
Position, containment and the reference frame the position is given in.
Position, container and reference frame
Where a printer is, and what that position is measured against.
- What identifies and describes the location of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the location of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the location of a printer is known, and what must it refuse? action

- Who or what asserted this about the movement of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the movement of a printer is known, and what must it refuse? action
State and lifecycle The states a printer passes through and the events that move it between them.
Most decisions about a thing depend on what state it is in now, which is a claim with a time on it, not a property.

From coming into existence to ceasing to be one of these.
Stages and transitions
The stages worth naming and what moves a printer between them.
- What identifies and describes the lifecycle of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the lifecycle of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the lifecycle of a printer is known, and what must it refuse? action
Observations and current status
What is observed about a printer, how often and by whom.
Observation record
How an observation of a printer is recorded so that it can be superseded rather than overwritten.
- What identifies and describes an observation of a printer, and in what units or vocabulary? definition
- Who or what asserted this about an observation of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once an observation of a printer is known, and what must it refuse? action
Safety, rules and constraints How a printer can hurt someone, and what the rules say about it.
A model of a thing that can cause harm has to carry the harm and the rule, or the agent will infer neither.
Hazards and mitigations
What goes wrong, to whom, and what prevents it.
Hazard profile and mitigations
The ways a printer causes harm and the measures that reduce it.
- What identifies and describes the hazards of a printer, and in what units or vocabulary? definition
- Who or what asserted this about the hazards of a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the hazards of a printer is known, and what must it refuse? action

The rules that bind an agent acting on a printer, with the jurisdiction they hold in.
- What identifies and describes the rules covering a printer, and in what units or vocabulary? definition
- Who or what asserted this about the rules covering a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the rules covering a printer is known, and what must it refuse? action
Function and operating principle What printer is for and how it achieves it.
Two devices with the same name can work on different principles, and the principle is what predicts failure and constrains use.
Intended function
The job it does, and the jobs it is used for anyway.
Function, principle and variants
What it does, how, and which variants do it differently.
- What function does printer perform, on what operating principle, and which variants differ in that principle? definition
- What use falls outside the intended function but happens in practice? boundary
Capacity and rating
The numbers that say what it can do and where it stops.
Ratings and their conditions
Rated capacity, power, throughput and the conditions each assumes.
- What ratings characterise printer, in what units, and under what stated conditions? measurement
- What happens beyond the rating - degradation, refusal, damage - and how is that detected? action
Operation, controls and state How printer is operated and what state it is in right now.
An agent acting on a device needs its current state and the controls that change it, not just its specification.
Controls and modes
What can be set, what that changes, and what is interlocked.
Control surface and interlocks
The settings available and the conditions that block them.
- What controls and modes does printer have, and what does each change? definition
- Which actions are interlocked or forbidden in which state, and what must be true before acting? action
Condition and maintenance
Wear, service intervals, consumables and the line between working and broken.
Condition, service and consumables
What is consumed, what is serviced, and how condition is judged.
- What consumables and service does printer need, at what interval, and on whose authority? measurement
- What evidence separates a unit that is working from one that is out of service? boundary
Kind, model and unit Whether a claim about printer is about the kind, a product line, or one physical unit.
This is the boundary most often got wrong for made things, and getting it wrong mixes a catalogue entry with the machine in the yard.
Level of reference
The three levels and what belongs at each.
What belongs to kind, model and unit
Which properties are shared by all of them and which are not.
- Which facts about printer hold for every one of them, which for a model, and which only for one unit? boundary
- What identifies an individual unit, and what should an agent do when it has only the kind? action
Standards and conformity
The standards a working example must meet and who attests it.
Standards, marks and attestation
Which standard applies, who certifies, and what the mark means.
- Which standards govern printer, issued by whom, and what does conformity actually assert? provenance
- What may an agent conclude from a certification mark, and what may it not? boundary
Provenance, evidence and time Where every claim about a printer came from and when it held.
A claim without a source and a time cannot be superseded, only overwritten, and an agent that overwrites loses the ability to explain itself.
Source and authority
Who said it, on what evidence, and how strongly.
Claim provenance and confidence
The authority behind each claim about a printer and how confident it is.
- What identifies and describes a claim about a printer, and in what units or vocabulary? definition
- Who or what asserted this about a claim about a printer, by which method, and when was it true? provenance
- What may an agent decide or do once a claim about a printer is known, and what must it refuse? action
Time, versions and supersession
When a claim was true, when it was learnt, and what replaced it.
Validity period and supersession
How an old claim about a printer is retired without being erased.
- What identifies and describes the validity of a claim about a printer, and in what units or vocabulary? definition
- Who or what asserted this about the validity of a claim about a printer, by which method, and when was it true? provenance
- What may an agent decide or do once the validity of a claim about a printer is known, and what must it refuse? action
