Thing Registry Cross-cutting context

Generated draft, first pass

This model was drafted by rule from what the registry knows about the thing. It proposes which bundles a real model will need and which questions research must answer. It is not researched and no sentence in it is sourced.

Written from the archetype playbook - what this kind of thing needs beyond identity and provenance - and from the structure that recurred across 6,333 models already researched by two engines. Applied to this entry by rule. No source was read for this thing and no claim here is researched. This entry carries no facets of its own, so they were inferred from its domain - a guess about a whole domain applied to one thing.

Generator: vr.draft.v3

Purpose and description

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

A cross-cutting notion registered under XCT.QLT. The registry names it; this draft has not been given a definition yet.

It can be observed and measured.

Distinguishing features

Described in 52 Wikipedia languages, which is a measure of how widely the thing is known, not of how important it is.

Physical character

Made of: an abstraction with no physical instance.

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.

How it is recognised

Nothing to see. What is recognised is an instance of it, and which instances count is exactly what is argued about.

Described in 52 Wikipedia languages, which measures how widely it is written about rather than how important or how common it is.

Drafted structure

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 12 findings · 32 questions.

Identity, naming and classification How an agent tells one cauchy sequence from another, and a cauchy sequence 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 cauchy sequence, and in what units or vocabulary? definition
  2. Who or what asserted this about the name of a cauchy sequence, by which method, and when was it true? provenance
  3. What may an agent decide or do once the name of a cauchy sequence 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 cauchy sequence, and in what units or vocabulary? definition
  2. Who or what asserted this about an identifier for a cauchy sequence, by which method, and when was it true? provenance
  3. What may an agent decide or do once an identifier for a cauchy sequence is known, and what must it refuse? action

Classification and granularity

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

Distinguishing features

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

  1. What identifies and describes what distinguishes a cauchy sequence, and in what units or vocabulary? definition
  2. Who or what asserted this about what distinguishes a cauchy sequence, by which method, and when was it true? provenance
  3. What may an agent decide or do once what distinguishes a cauchy sequence is known, and what must it refuse? action
State and lifecycle The states a cauchy sequence 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 cauchy sequence between them.

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

Observations and current status

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

Observation record

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

  1. What identifies and describes an observation of a cauchy sequence, and in what units or vocabulary? definition
  2. Who or what asserted this about an observation of a cauchy sequence, by which method, and when was it true? provenance
  3. What may an agent decide or do once an observation of a cauchy sequence is known, and what must it refuse? action
Definitions and who holds them What cauchy sequence is taken to mean, and by whom.

When a field disagrees about a concept, the disagreement is the content. A model that picks one definition silently destroys the information.

Competing definitions

The main readings and the traditions behind them.

Definitions and their holders

Each definition with the school or body that holds it.

  1. Which definitions of cauchy sequence are in use, and which tradition or body holds each? definition
  2. What turns on the difference between them in practice? boundary

Operationalisation

How it is measured or applied when it has to be.

Measures and proxies

Instruments and indicators used to stand in for it.

  1. How is cauchy sequence operationalised or measured in practice, and by what instrument? measurement
  2. What does that operationalisation leave out, and when does that matter? boundary
Instances, use and consequence What counts as an instance of cauchy sequence and what follows from calling something that.

Applying a concept is an act with consequences, so a model must say what the label licenses and what it does not.

What counts as an instance

Clear cases, borderline cases and non-cases.

Tests for an instance

What would settle whether something falls under it.

  1. What would settle whether something is an instance of cauchy sequence? boundary
  2. Which borderline cases are argued about, and on what grounds? definition

Consequence of application

Rights, duties or decisions that follow from the label.

What the label licenses

What an agent may do once something is classified this way.

  1. What follows practically once something is treated as cauchy sequence? action
  2. What must an agent not infer from the label alone? action
Provenance, evidence and time Where every claim about a cauchy sequence 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 cauchy sequence and how confident it is.

  1. What identifies and describes a claim about a cauchy sequence, and in what units or vocabulary? definition
  2. Who or what asserted this about a claim about a cauchy sequence, by which method, and when was it true? provenance
  3. What may an agent decide or do once a claim about a cauchy sequence 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 cauchy sequence is retired without being erased.

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

What the second pass must settle

  • Which of the bundles below does a real task actually need, and which are ceremony?
  • What does this thing have that the facets do not capture at all?
  • Which neighbouring kind is most often confused with a cauchy sequence, and on what evidence are they told apart?
