What it is Derived, awaiting review
This meta-model describes chemical substances and engineered materials as classes of matter: what they are made of, how they behave, how hazardous they are, and where physical stocks of them exist as lots.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Materials and chemical substances
Distinguishing features Derived, awaiting review
- It is its own model because substance-level facts (identity, composition, hazard) are class knowledge maintained once for the whole world, while every other model in the catalogue that touches matter (items, foods, medicines, artifacts) only points at these classes instead of restating chemistry.

Owners Filled
Steward
Class-level substance and material records are stewarded by a standards registrar archetype that curates identity, composition and hazard facts; each lot record is stewarded by its holder.
Links to other meta-models Filled
references
- world.physicalItem - a lot stored in a drum or container is containerized as an identifiable item; item-level material declarations point back at classes here.
- world.place - production and storage sites of lots resolve to place identities rather than local address fields.
- world.foodDrink - ingredient and active-substance links resolve into this model; world.culturalArtifact (M9) resolves materials and techniques here.
- world.medicine - ingredient and active-substance links resolve into this model; world.culturalArtifact (M9) resolves materials and techniques here.

What else AI and robots need to interact with it Incomplete
Identity and identifiers required Derived, awaiting review
- substance: a single chemical entity; key attributes: registry identifiers, molecular formula, structure reference, form.
- identifierRecord: an assignment of an external registry identifier to a substance or material; key attributes: scheme, code, assignment date.
Direct properties not applicable Not applicable
Not applicable
Institutional or informational subject: no invented physical properties.
Recognition optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Capabilities and actions required Derived, awaiting review
- substanceRegistered: a new substance or material class entered the model with its initial identity.
- compositionRevised: the declared composition of a material changed (reformulation, purity change).
- propertyDetermined: a measurement or authoritative declaration added a property value.
- hazardReclassified: the hazard classification of a class changed under a scheme revision or new evidence.
- lotProduced: a bounded quantity of a class came into existence with a lot code.
- lotTransferred: custody of a lot moved to another holder.
- lotDepleted: a lot was consumed, disposed of or otherwise ceased to exist as stock.
Legacy events listed as state transitions.
Hazards and failure modes optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Standards and interfaces required Derived, awaiting review
- safetyDataAccess: read access to hazard and precaution layers for anyone handling or transporting the class; typically broad, since safety data is meant to travel with the matter.
- stockDisclosure: holder-granted visibility of lot quantities and locations to a named counterparty (auditor, insurer, buyer).
- classificationFeed: subscription to reclassification and composition-revision events for downstream models that embed references to this one.
- safetyDataSheetView: identity, hazard, handling and stability for one class; omits stock, holders and commercial context.
- transportView: hazard class, packing and segregation facts needed by carriers; omits composition detail and property history.
- catalogueChemistryView: identity, nomenclature and key properties for catalogue builders; omits lots and precaution text.
Context of use required Filled
- Access to any record is granted by its owner through the catalogue's S1/S2 ownership and access models, with changes traceable via S4 audit.
