Bundle → Layer → Finding → Questions Derived, awaiting review

8 bundles · 17 layers · 19 findings · 53 questions

Identity, naming and classification How an agent tells one snowdrift from another, and a snowdrift 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.

  1. What identifies and describes the name of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the name of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the name of a snowdrift 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.

  1. What identifies and describes an identifier for a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about an identifier for a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once an identifier for a snowdrift is known, and what must it refuse? action

Classification and granularity

Where a snowdrift 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.

  1. What identifies and describes the kind of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the kind of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the kind of a snowdrift is known, and what must it refuse? action

Distinguishing features

What separates a snowdrift from the things most often confused with it.

  1. What identifies and describes what distinguishes a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about what distinguishes a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once what distinguishes a snowdrift is known, and what must it refuse? action
Form, composition and condition What a snowdrift 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 geographic scale.

Measurable dimensions and their units

The quantities worth recording and the units they are recorded in.

  1. What identifies and describes the dimensions of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the dimensions of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the dimensions of a snowdrift is known, and what must it refuse? action

Material and composition

Materials, parts and how they are put together.

Parts and materials

What a snowdrift is built from and which parts are replaceable.

  1. What identifies and describes the composition of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the composition of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the composition of a snowdrift is known, and what must it refuse? action

Wear, damage, health and the difference between working and broken.

Condition, damage and health

How the condition of a snowdrift is judged and by whom.

  1. What identifies and describes the condition of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the condition of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the condition of a snowdrift is known, and what must it refuse? action
Place and movement Where a snowdrift is, how it got there and where it may go (fixed).

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 snowdrift is, and what that position is measured against.

  1. What identifies and describes the location of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the location of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the location of a snowdrift is known, and what must it refuse? action

  2. Who or what asserted this about the movement of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the movement of a snowdrift is known, and what must it refuse? action
State and lifecycle The states a snowdrift 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 snowdrift between them.

  1. What identifies and describes the lifecycle of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the lifecycle of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the lifecycle of a snowdrift is known, and what must it refuse? action

Observations and current status

What is observed about a snowdrift, how often and by whom.

Observation record

How an observation of a snowdrift is recorded so that it can be superseded rather than overwritten.

  1. What identifies and describes an observation of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about an observation of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once an observation of a snowdrift is known, and what must it refuse? action
Use and operation What can be done with a snowdrift 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 snowdrift is for, and what it is used for anyway.

Function, purpose and misuse

The function a snowdrift performs and the uses that fall outside it.

  1. What identifies and describes the use of a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the use of a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once the use of a snowdrift is known, and what must it refuse? action

What an agent needs before it can act on a snowdrift at all.

  1. What identifies and describes handling a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about handling a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once handling a snowdrift is known, and what must it refuse? action
Extent, geometry and naming Where snowdrift is, how far it reaches, and what it is called.

A boundary is claimed by an authority rather than observed in the world, so the claimant belongs in the record with the geometry.

Geometry and reference system

Coordinates, extent and the frame they are given in.

Geometry, precision and frame

What is recorded about position and shape, and to what accuracy.

  1. What geometry describes snowdrift, in which coordinate reference system, at what precision? measurement
  2. Which authority publishes that geometry, and who publishes a different one? provenance

Names and endonyms

What it is called in different languages and by different parties.

Names and who uses them

Official names, local names and contested names.

  1. By what names is snowdrift known, in which languages, and which are official to whom? definition
  2. Where naming is contested, what should an agent record instead of choosing? action
Containment, jurisdiction and access What snowdrift sits inside, who governs it, and who may enter.

Administrative containment decides which rules apply, and it changes without the place moving.

Administrative containment

The units it belongs to and the date each holds from.

Containing units and effective dates

Where it sits administratively and since when.

  1. Which administrative units contain snowdrift, and since when does each containment hold? definition
  2. Which containment is disputed, and by which parties? boundary

Access and permitted use

Who may enter or use it and under what conditions.

Access rules and their source

Entry, use and restriction, with the rule behind each.

  1. Who may enter or use snowdrift, under what conditions, and by whose rule? action
  2. What seasonal or conditional closure applies, and how is it announced? definition
Provenance, evidence and time Where every claim about a snowdrift 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 snowdrift and how confident it is.

  1. What identifies and describes a claim about a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about a claim about a snowdrift, by which method, and when was it true? provenance
  3. What may an agent decide or do once a claim about a snowdrift is known, and what must it refuse? action

How an old claim about a snowdrift is retired without being erased.

  1. What identifies and describes the validity of a claim about a snowdrift, and in what units or vocabulary? definition
  2. Who or what asserted this about the validity of a claim about a snowdrift, by which method, and when was it true? provenance

A physical thing registered under PHY.PLC. The registry names it; this draft has not been given a definition yet.

Why it exists Derived, awaiting review

Give an agent a durable, checkable way to recognise a snowdrift, record what state it is in, and decide what may be done with it.

Distinguishing features Derived, awaiting review

  • Described in 29 Wikipedia languages, which is a measure of how widely the thing is known, not of how important it is.

What robots and AI may and may not do Derived, awaiting review

May

  • observe it, measure it, record its state
  • enter it, cross it, travel along it

Direct properties required Derived, awaiting review

  • Made of: a portion of the world with an extent
  • On the scale of a landscape, measured in kilometres.
  • Stays where it was put; moving it is a project.
  • Does nothing on its own; everything it does, something else did to it.
  • These come from the domain this entry sits in rather than from the entry itself, so treat them as a first guess about the whole domain applied to one thing.

Recognition required Derived, awaiting review

  • Recognised by extent on the ground and by position, not by appearance. Two places that look alike are told apart by where they are.

Capabilities and actions required Derived, awaiting review

  • observed and measured
  • entered, crossed or travelled along

Not described yet. This gap is in the card backlog.

Standards and interfaces required Missing, in the backlog

Not described yet. This gap is in the card backlog.

Context of use required Derived, awaiting review

  • Described in 29 Wikipedia languages, which measures how widely it is written about rather than how important or how common it is.

Sources Missing, in the backlog
