Vocabulary

The Particles vocabulary namespace is https://linkedparticles.org/vocab#.

Every term below is a # fragment of this page: the JSON-LD @context and the SHACL shapes name terms as particles:<term>, which expands to https://linkedparticles.org/vocab#<term> and resolves here. The normative definitions live in the technical specification; this page is the dereferenceable index of the identifiers themselves.

Terms are stable; this page is generated

This page is rendered at build time from the canonical context.jsonld, so it cannot drift from the artifact a consumer actually fetches.

Property terms

Each row is one vocabulary term and the JSON key (or keys) that bind to it, with the JSON-LD typing the context declares.

Individual terms

The enumerated values — lifecycle status and PSUM uncertainty nature — carry IRIs of their own so a serialized particle names them by identifier rather than by string.

Terms mapped into external vocabularies

Where an established vocabulary already has the term, the context maps onto it instead of minting a Particles IRI. These identifiers dereference at their own hosts, not here.

Prefixes the context declares. The Particles ones are extension-scoped: they namespace the domain-specific fields an extractor may attach, and carry no terms in the core context.
