MIF Namespace

Base IRI: https://mif-spec.dev/ns/

The MIF vocabulary defines the terms used by the JSON-LD projection of MIF concept documents. It is the @vocab base of the canonical context at /schema/context.jsonld. Term IRIs follow the pattern https://mif-spec.dev/ns/<Term> (for example https://mif-spec.dev/ns/Concept).

This page is derived from the canonical context, so it stays in step with the schema. The same vocabulary is available as a machine-readable RDFS document:

• Machine-readable vocabulary: /ns/vocabulary.jsonld
• Canonical JSON-LD context: /schema/context.jsonld

MIF also reuses Dublin Core (dc), Schema.org (schema), W3C PROV (prov), and XML Schema (xsd) terms. Those are defined by their own vocabularies and are not redefined here.
