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

Identity, naming and classification How an agent tells one period from another, and a period 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 period, and in what units or vocabulary? definition
- Who or what asserted this about the name of a period, by which method, and when was it true? provenance
- What may an agent decide or do once the name of a period 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 period, and in what units or vocabulary? definition
- Who or what asserted this about an identifier for a period, by which method, and when was it true? provenance
- What may an agent decide or do once an identifier for a period is known, and what must it refuse? action
Classification and granularity
Where a period 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 period, and in what units or vocabulary? definition
- Who or what asserted this about the kind of a period, by which method, and when was it true? provenance
- What may an agent decide or do once the kind of a period is known, and what must it refuse? action
Distinguishing features
What separates a period from the things most often confused with it.
- What identifies and describes what distinguishes a period, and in what units or vocabulary? definition
- Who or what asserted this about what distinguishes a period, by which method, and when was it true? provenance
- What may an agent decide or do once what distinguishes a period is known, and what must it refuse? action
State and lifecycle The states a period 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 period between them.
- What identifies and describes the lifecycle of a period, and in what units or vocabulary? definition
- Who or what asserted this about the lifecycle of a period, by which method, and when was it true? provenance
- What may an agent decide or do once the lifecycle of a period is known, and what must it refuse? action
Observations and current status
What is observed about a period, how often and by whom.
Observation record
How an observation of a period is recorded so that it can be superseded rather than overwritten.
- What identifies and describes an observation of a period, and in what units or vocabulary? definition
- Who or what asserted this about an observation of a period, by which method, and when was it true? provenance
- What may an agent decide or do once an observation of a period is known, and what must it refuse? action
Temporal extent and dating When period began and ended, and who says so.
Dates for events are conventions held by historiographies that disagree, and a single confident date hides the disagreement.
Dating and calendar
Start, end, granularity and the calendar used.
Dates, granularity and authority
What is dated, how precisely, and on whose account.
- What start and end are conventionally given for period, at what granularity, in which calendar? definition
- Which accounts date it differently, and on what grounds? provenance
What counts as part of it
Sub-events included or excluded, and by whom.
Inclusion and exclusion
The episodes treated as inside the event and those left out.
- Which episodes are counted as part of period, and which are treated as separate? boundary
- Whose framing is being followed in that inclusion, and who frames it otherwise? provenance
Participants, causes and consequences Who took part in period and what is claimed to follow from it.
Causation around events is asserted rather than observed, so each claim needs the party asserting it.
Participants and roles
Parties involved and what each did.
Parties and their roles
Who is recorded as involved and in what capacity.
- Which parties took part in period, in what roles, and on whose account? provenance
- Where do accounts disagree about who was involved? boundary
Causes and consequences
What is claimed to have caused it and followed from it.
Causal claims and who makes them
Antecedents and outcomes as attributed claims.
- What causes and consequences are attributed to period, and by whom? provenance
- What would an agent need before treating such a claim as settled rather than contested? action
Provenance, evidence and time Where every claim about a period 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 period and how confident it is.
- What identifies and describes a claim about a period, and in what units or vocabulary? definition
- Who or what asserted this about a claim about a period, by which method, and when was it true? provenance
- What may an agent decide or do once a claim about a period 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 period is retired without being erased.
- What identifies and describes the validity of a claim about a period, and in what units or vocabulary? definition
- Who or what asserted this about the validity of a claim about a period, by which method, and when was it true? provenance
- What may an agent decide or do once the validity of a claim about a period is known, and what must it refuse? action

What it is Derived, awaiting review
A cross-cutting notion registered under XCT.TME. 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 period, 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: period of data elements, sound period, sampling period, appreciation period, slack water, Eclipse season.
- 6 finer distinctions are held as aliases rather than separate entries, because telling them apart needs a task that asks for it.
- Described in 27 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
- Not a thing to see. Recognised by when it happened and who was involved, on the account of somebody.
