sewer network
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 sewer network, record what state it is in, and decide what may be done with it.
A physical thing registered under PHY.OBJ. The registry names it; this draft has not been given a definition yet.
It can be observed and measured.
Distinguishing features
Names folded into this entry, which a task may need to split apart again: open sewer, Water supply in Stockholm, Water supply in Goulburn, storage tunnel, sanitary sewer network, Sewer and water channels (Icheri Sheher), sewer vent, combined sewer network, Vacuum sewer, sanitary dump station, Effluent sewer, Vacuum sewerage.
12 finer distinctions are held as aliases rather than separate entries, because telling them apart needs a task that asks for it.
Described in 68 Wikipedia languages, which is a measure of how widely the thing is known, not of how important it is.
Physical character
Made of: matter you can touch.
Mobility varies between examples.
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
Recognised by form, by the arrangement of its controls, and by markings - a plate, a model number, a certification mark. Form alone rarely separates two models that do very different things.

Bundle to layer to finding to question, as the second pass will find it: 8 bundles · 17 layers · 19 findings · 51 questions.
Identity, naming and classification How an agent tells one sewer network from another, and a sewer network 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.

Form, composition and condition What a sewer network 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.
Measurable dimensions and their units
The quantities worth recording and the units they are recorded in.
- What identifies and describes the dimensions of a sewer network, and in what units or vocabulary? definition

- Who or what asserted this about the condition of a sewer network, by which method, and when was it true? provenance
- What may an agent decide or do once the condition of a sewer network is known, and what must it refuse? action
Place and movement Where a sewer network is, how it got there and where it may go (varies).
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 sewer network is, and what that position is measured against.
- What identifies and describes the location of a sewer network, and in what units or vocabulary? definition

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

- Who or what asserted this about an observation of a sewer network, by which method, and when was it true? provenance
- What may an agent decide or do once an observation of a sewer network is known, and what must it refuse? action
Function and operating principle What sewer network is for and how it achieves it.
Two devices with the same name can work on different principles, and the principle is what predicts failure and constrains use.
Intended function
The job it does, and the jobs it is used for anyway.
Function, principle and variants
What it does, how, and which variants do it differently.
- What function does sewer network perform, on what operating principle, and which variants differ in that principle? definition

- What ratings characterise sewer network, in what units, and under what stated conditions? measurement
- What happens beyond the rating - degradation, refusal, damage - and how is that detected? action
Operation, controls and state How sewer network is operated and what state it is in right now.
An agent acting on a device needs its current state and the controls that change it, not just its specification.
Controls and modes
What can be set, what that changes, and what is interlocked.
Control surface and interlocks
The settings available and the conditions that block them.
- What controls and modes does sewer network have, and what does each change? definition
- Which actions are interlocked or forbidden in which state, and what must be true before acting? action
Condition and maintenance
Wear, service intervals, consumables and the line between working and broken.
Condition, service and consumables
What is consumed, what is serviced, and how condition is judged.
- What consumables and service does sewer network need, at what interval, and on whose authority? measurement
- What evidence separates a unit that is working from one that is out of service? boundary
Kind, model and unit Whether a claim about sewer network is about the kind, a product line, or one physical unit.
This is the boundary most often got wrong for made things, and getting it wrong mixes a catalogue entry with the machine in the yard.
Level of reference
The three levels and what belongs at each.
What belongs to kind, model and unit
Which properties are shared by all of them and which are not.
- Which facts about sewer network hold for every one of them, which for a model, and which only for one unit? boundary
- What identifies an individual unit, and what should an agent do when it has only the kind? action
Standards and conformity
The standards a working example must meet and who attests it.
Standards, marks and attestation
Which standard applies, who certifies, and what the mark means.
- Which standards govern sewer network, issued by whom, and what does conformity actually assert? provenance
- What may an agent conclude from a certification mark, and what may it not? boundary
Provenance, evidence and time Where every claim about a sewer network 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.

The authority behind each claim about a sewer network and how confident it is.
- What identifies and describes a claim about a sewer network, and in what units or vocabulary? definition

How an old claim about a sewer network is retired without being erased.
- What identifies and describes the validity of a claim about a sewer network, and in what units or vocabulary? definition
- Who or what asserted this about the validity of a claim about a sewer network, by which method, and when was it true? provenance
- What may an agent decide or do once the validity of a claim about a sewer network is known, and what must it refuse? action
