Description

One constituent in an IngredientRecord.components has-part assertion. The component may resolve to the current MIM catalog, deliberately name an external ontology/registry term, or remain unmapped; reference_scope makes those cases explicit. This class does not represent an identity mapping or a relationship among chemical forms.

Attributes

Component name

Name: component_name
Description: Component ingredient name as listed in the supporting source (e.g. "FeCl3 x 6 H2O").
From schema: https://w3id.org/mediaingredientmech
Required: True

Component id

Name: component_id
Description: Semantic CURIE for the component (e.g. CHEBI:..., MICRO:..., or cas:...). It is not unconditionally a foreign key to one MIM row: reference_scope states whether the CURIE is represented in MIM or deliberately external. Omit only when reference_scope is UNMAPPED.
From schema: https://w3id.org/mediaingredientmech
Pattern: ^[A-Za-z][A-Za-z0-9.]*:[A-Za-z0-9][A-Za-z0-9._~-]*$

Reference scope

Name: reference_scope
Description: Resolution status and intended scope of component_id.
From schema: https://w3id.org/mediaingredientmech
Range: ComponentReferenceScopeEnum
Required: True

Concentration value

Name: concentration_value
Description: Amount/concentration of the component, kept as a string to preserve the source's formatting (e.g. "1.5", "0.1-0.5").
From schema: https://w3id.org/mediaingredientmech

Concentration unit

Name: concentration_unit
Description: Unit for concentration_value (e.g. G_PER_L, MG_PER_L, M, MM, PERCENT).
From schema: https://w3id.org/mediaingredientmech

Source

Name: source
Description: Legacy free-text component provenance retained for compatibility; it may duplicate component_assertion.evidence. New curation should put record-level decomposition method and structured evidence in component_assertion, using this slot only when a part has additional component-specific provenance.
