Crate mif_core 

Shared foundational types for the MIF (Modeled Information Format) ecosystem.

mif-core provides the types shared across the ecosystem’s other crates: OntologyReference, EntityReference, EntityData, and ConceptType, plus the concept-URN helpers (concept_urn, is_concept_urn) for the urn:mif:<uuid> id form MIF 1.4.0 requires. Field definitions are taken directly from the canonical MIF JSON Schema (mif.schema.json, entity-reference.schema.json, draft 2020-12; see https://mif-spec.dev/schema/).

Validation of MIF documents against the schema itself lives in the mif-schema crate; mif-core only defines the shared data shapes.

Structs

EntityData

Open, ontology-typed entity payload for a memory that is an entity.

EntityId

The entity identifier object nested inside an EntityReference.

EntityReference

Closed pointer to an entity mentioned by a MIF memory.

OntologyReference

A reference to the ontology a MIF memory conforms to.

Enums

ConceptType

MIF’s three-way knowledge taxonomy.

EntityType

Entity type classification: a closed vocabulary of well-known types, or a custom ontology-defined type (^[a-z][a-z0-9-]*$) preserved verbatim.

KnownEntityType

The closed set of well-known entity type values.

Constants

CONCEPT_URN_PREFIX

The URN prefix of a concept @id.

Functions

concept_urn

The concept URN urn:mif:<uuid> for name.

concept_uuid

The deterministic concept UUID for name (version 5, in mif_namespace).

is_concept_urn

Whether id is a valid concept URN: urn:mif: followed by a hyphenated UUID, the form mif.schema.json’s @id pattern accepts.

mif_namespace

The version-5 UUID namespace for derived concept ids: uuid5(NAMESPACE_URL, "https://mif-spec.dev").
