JSON-LD Contexts

Semantic contexts for metadata interoperability.

Overview

JSON-LD contexts enable OpenMetadata JSON documents to be interpreted as linked data, enabling semantic interoperability with other systems.

Features

Semantic Interoperability

Transform JSON metadata into RDF using JSON-LD contexts.

Vocabulary Mapping

Map OpenMetadata terms to standard vocabularies and ontologies.

Linked Data

Enable URIs and semantic relationships in JSON documents.

Usage

JSON-LD contexts allow metadata to be both: - Valid JSON for easy consumption by applications - Valid RDF for semantic web applications

Version 2.0 Contexts

Alongside the base, data asset, service, governance, quality, team, and operations mappings, version 2.0 adds dedicated contexts for:

  • activity.jsonld — Activity Stream events and configuration
  • ai.jsonld — AI, LLM, MCP, AI governance frameworks, controls, and audit reports
  • announcement.jsonld — standalone announcements
  • contextCenter.jsonld — Context Center content, files, folders, attachments, and memories
  • intakeForm.jsonld — governance intake forms
  • task.jsonld — first-class tasks and task form schemas

The Task term in task.jsonld maps to om:GovernanceTask. This keeps the new first-class task entity distinct from the pre-existing om:Task term used for a task nested inside a data pipeline.
