7 bundles · 15 layers · 17 findings · 49 questions
Identity, naming and classification How an agent tells one meter from another, and a meter 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 meter, and in what units or vocabulary? definition
- Who or what asserted this about the name of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the name of a meter 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 meter, and in what units or vocabulary? definition
- Who or what asserted this about an identifier for a meter, by which method, and when was it true? provenance
- What may an agent decide or do once an identifier for a meter is known, and what must it refuse? action
Classification and granularity
Where a meter 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 meter, and in what units or vocabulary? definition
- Who or what asserted this about the kind of a meter, by which method, and when was it true? provenance

Distinguishing features
What separates a meter from the things most often confused with it.
- What identifies and describes what distinguishes a meter, and in what units or vocabulary? definition
- Who or what asserted this about what distinguishes a meter, by which method, and when was it true? provenance
- What may an agent decide or do once what distinguishes a meter is known, and what must it refuse? action
Form, composition and condition What a meter 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 meter, and in what units or vocabulary? definition
- Who or what asserted this about the dimensions of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the dimensions of a meter is known, and what must it refuse? action
Material and composition
Materials, parts and how they are put together.
Parts and materials
What a meter is built from and which parts are replaceable.
- What identifies and describes the composition of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the composition of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the composition of a meter 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 meter is judged and by whom.
- What identifies and describes the condition of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the condition of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the condition of a meter is known, and what must it refuse? action
Place and movement Where a meter 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 meter is, and what that position is measured against.
- What identifies and describes the location of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the location of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the location of a meter is known, and what must it refuse? action
Movement and transfer
How a meter is carried, installed or relocated.
Movement events and constraints
What counts as a movement, what records it and what limits it.
- What identifies and describes the movement of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the movement of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the movement of a meter is known, and what must it refuse? action
State and lifecycle The states a meter 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.
Lifecycle stages
From coming into existence to ceasing to be one of these.
Stages and transitions
The stages worth naming and what moves a meter between them.
- What identifies and describes the lifecycle of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the lifecycle of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the lifecycle of a meter is known, and what must it refuse? action
Observations and current status
What is observed about a meter, how often and by whom.
Observation record
How an observation of a meter is recorded so that it can be superseded rather than overwritten.
- What identifies and describes an observation of a meter, and in what units or vocabulary? definition
- Who or what asserted this about an observation of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once an observation of a meter is known, and what must it refuse? action
Use and operation What can be done with a meter and what it takes to do it.
An agent that can recognise a thing but not act on it has only half a model.
Intended use and function
What a meter is for, and what it is used for anyway.
Function, purpose and misuse
The function a meter performs and the uses that fall outside it.
- What identifies and describes the use of a meter, and in what units or vocabulary? definition
- Who or what asserted this about the use of a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the use of a meter is known, and what must it refuse? action

- Who or what asserted this about handling a meter, by which method, and when was it true? provenance
- What may an agent decide or do once handling a meter is known, and what must it refuse? action
Definition, dimension and realisation What meter is defined as and how it is realised in practice.
A unit is not the quantity it measures, and its definition has a history that older data still depends on.
Definition and dimension
The defining relation and the quantity it measures.
Definition, body and date
What defines it now, and what defined it before.
- How is meter defined, by which body, and since when? definition
- What was the previous definition, and what data still depends on it? provenance
Conversion and compatibility
Relations to other units, exact or approximate.
Conversions and their exactness
Factors, and whether each is exact by definition.
- What conversions relate meter to other units, and which are exact by definition? measurement
- Where does rounding a conversion change a decision, and how should that be recorded? action
Provenance, evidence and time Where every claim about a meter 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 meter and how confident it is.
- What identifies and describes a claim about a meter, and in what units or vocabulary? definition
- Who or what asserted this about a claim about a meter, by which method, and when was it true? provenance
- What may an agent decide or do once a claim about a meter 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 meter is retired without being erased.
- What identifies and describes the validity of a claim about a meter, and in what units or vocabulary? definition
- Who or what asserted this about the validity of a claim about a meter, by which method, and when was it true? provenance
- What may an agent decide or do once the validity of a claim about a meter is known, and what must it refuse? action

Why it exists Derived, awaiting review
Give an agent a durable, checkable way to recognise a meter, record what state it is in, and decide what may be done with it.
Distinguishing features Derived, awaiting review
- Names folded into this entry, which a task may need to split apart again: ammeter, astatic galvanometer, ballistic galvanometer, digital voltmeter, electric meter, power meter, electrometer, electronic voltmeter, fluxmeter, galvanometer, gas meter, gasometer.
- 26 finer distinctions are held as aliases rather than separate entries, because telling them apart needs a task that asks for it.
What robots and AI may and may not do Derived, awaiting review
May
- pick it up, hold it, put it somewhere else
- operate it, set it, turn it on and off
