Give an agent a durable, checkable way to recognise a Legg–Calvé–Perthes disease, record what state it is in, and decide what may be done with it.

Thing Registry Cross-cutting context XCT.STA

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.

5 bundles · 10 layers · 12 findings · 32 questions

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

Classification and granularity

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

Distinguishing features

What separates a Legg–Calvé–Perthes disease from the things most often confused with it.

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

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

Observations and current status

What is observed about a Legg–Calvé–Perthes disease, how often and by whom.

Observation record

How an observation of a Legg–Calvé–Perthes disease is recorded so that it can be superseded rather than overwritten.

  1. What identifies and describes an observation of a Legg–Calvé–Perthes disease, and in what units or vocabulary? definition
  2. Who or what asserted this about an observation of a Legg–Calvé–Perthes disease, by which method, and when was it true? provenance
  3. What may an agent decide or do once an observation of a Legg–Calvé–Perthes disease is known, and what must it refuse? action
Diagnosis, criteria and coding What makes a case of Legg–Calvé–Perthes disease a case, and under which revision.

Criteria change between revisions, so a diagnosis without its coding revision cannot be compared with a later one.

Diagnostic criteria

The criteria in force and who issues them.

Criteria, issuer and revision

What must be true for a diagnosis, according to whom.

  1. What criteria define Legg–Calvé–Perthes disease, issued by which body, in which revision? definition
  2. What changed between revisions that would reclassify existing cases? boundary

Coding and terminology

The codes used to record it and their mapping.

Codes and mappings

Which classification codes apply and how they map.

  1. Which classification and terminology codes cover Legg–Calvé–Perthes disease, and how do they map to each other? definition
  2. What is lost when a case is mapped from one scheme to another? boundary
Course, population and care How Legg–Calvé–Perthes disease develops, whom it affects, and what is done about it.

The condition, the diagnosis and the episode of care are three different things, and an agent must not merge them.

Course and stages

Onset, progression, remission and outcome.

Stages and transitions

The stages recorded and what moves a case between them.

  1. What course does Legg–Calvé–Perthes disease typically take, and what marks each stage? definition
  2. What separates the condition itself from an episode of care for it? boundary

Affected populations

Who is affected, how often, and on what evidence.

Prevalence and its basis

Rates with their population, period and source.

  1. What prevalence or incidence is reported for Legg–Calvé–Perthes disease, in which population and period? measurement
  2. What may an agent not conclude about an individual from a population rate? action
Provenance, evidence and time Where every claim about a Legg–Calvé–Perthes disease 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 Legg–Calvé–Perthes disease and how confident it is.

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

  1. What identifies and describes the validity of a claim about a Legg–Calvé–Perthes disease, and in what units or vocabulary? definition
  2. Who or what asserted this about the validity of a claim about a Legg–Calvé–Perthes disease, 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 Legg–Calvé–Perthes disease is known, and what must it refuse? action

What it is Derived, awaiting review

A cross-cutting notion registered under XCT.STA. 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 Legg–Calvé–Perthes disease, record what state it is in, and decide what may be done with it.

Distinguishing features Derived, awaiting review

  • Described in 28 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

Direct properties not applicable Not applicable

  • 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.

Recognition optional Derived, awaiting review

  • Recognised by criteria applied to signs and findings, not by appearance. Two conditions can look identical and be distinguished only by test.

Capabilities and actions required Derived, awaiting review

  • observed and measured

Hazards and failure modes required Missing, in the backlog

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