Permanent Identifiers (PIDs)

This page lists the persistent, stable, and dereferenceable identifiers (PIDs) established by the Health-RI Semantic Interoperability Initiative. These URIs support semantic interoperability, long-term accessibility, and alignment with FAIR principles.

Initiative-Wide Identifier

URI: https://w3id.org/health-ri/semantic-interoperability

This URI refers to the Semantic Interoperability Initiative as a whole. It provides persistent access to the initiative’s public-facing resources and is suitable for citing the initiative in publications, websites, and metadata records.

Ontology Identifier

URI: https://w3id.org/health-ri/ontology

This is the main identifier for the Health-RI Ontology, which always resolves to the ontology's most recent version.

Identifiers for the Latest Ontology Version

These URIs point to the most recent release of the Health-RI Ontology and related documentation formats. The different URIs supports HTTP content negotiation to serve either machine-readable ontology files (e.g., Turtle) or human-readable documentation (HTML specification).

PID Description
/ontology/ttl OWL ontology in Turtle format
/ontology/specification HTML rendering of the ontology specification
/ontology/documentation Markdown documentation (raw version)
/ontology/json OntoUML model exported as JSON
/ontology/vpp OntoUML model file in Visual Paradigm format

Each of these URIs redirects to the latest available version of the resource.

Tip

You can use either /doc or /documentation, and /spec or /specification — both forms are valid and equivalent.

Identifiers for Versioned Ontology Releases

Each versioned release of the Health-RI Ontology is identified by its own dedicated URI in the format https://w3id.org/health-ri/ontology/vX.Y.Z. This URI is used as the owl:versionIRI in the ontology metadata.

To support traceability and reproducibility, each ontology release is also available via version-specific URIs.

Format

https://w3id.org/health-ri/ontology/vX.Y.Z/{format}

Where:

  • X.Y.Z is the semantic version (e.g., 2.0.0)
  • {format} is one of:
    • ttl — OWL ontology (Turtle)
    • vpp — OntoUML model (Visual Paradigm)
    • json — OntoUML model (JSON)
    • documentation — Markdown documentation
    • specification — HTML specification

Tip

You can also use the version URI without a {format} (e.g., /v0.6.0) to directly access the .ttl file.

Examples

  • https://w3id.org/health-ri/ontology/v0.6.0/ttl → Ontology in Turtle format for version 0.6.0

  • https://w3id.org/health-ri/ontology/v0.6.0/vpp → Visual Paradigm project file for version 0.6.0

  • https://w3id.org/health-ri/ontology/v0.9.1/documentation → Markdown documentation for version 0.9.1

  • https://w3id.org/health-ri/ontology/v0.6.0/specification → HTML specification for version 0.6.0

Overview of Persistent Identifiers

PID Description Behavior Example
/ontology Ontology root Content negotiation (RDF or HTML) https://w3id.org/health-ri/ontology
