What CNCF CloudEvents 1.0 - Event-Driven Workflow Interoperability Specification requires
CNCF CloudEvents 1.0 (CNCF Graduated Project, 2018, updated 2022) defines a vendor-neutral specification for describing event data in a common format to achieve interoperability across event-driven workflows, serverless platforms, and message brokers. Required envelope fields: specversion (must be '1.0'), id (unique per source), source (URI-reference), type (reverse-DNS identifier e.g. 'com.example.compliance.node.updated'), and datacontenttype (e.g. 'application/json'). Optional fields: subject, time (RFC 3339), dataschema, and extension attributes. Enables regulatory event streams (data changes, access logs, consent updates) to be produced and consumed across AWS EventBridge, Azure Event Grid, Google Cloud Pub/Sub, Apache Kafka, and NATS without platform lock-in.
