It builds on the earlier versions of UMF by adding richer typing, versioning support, and a builtin security envelope. The format is intentionally lightweight, humanreadable, and extensible, making it suitable for everything from IoT telemetry to enterprisegrade event streams.</p> </section> <section id="core-concepts"> <h2>Core Concepts</h2> <ul> <li><strong>Envelope</strong> Every UMF3 payload is wrapped in an envelope that contains metadata such as <code>messageId</code>, <code>timestamp</code>, <code>version</code>, and optional security fields.</li> <li><strong>Payload</strong> The actual business data. It can be any valid JSON value (object, array, string, number, boolean, or null).</li> <li><strong>Schema Reference</strong> A URI or compact identifier that points to the JSONSchema that validates the payload.</li> <li><strong>Versioning</strong> The <code>version</code> field in the envelope enables graceful evolution of the message contract.</li> <li><strong>Security</strong> Optional fields for digital signatures (<code>signature</code>) and encryption keys (<code>encryptedKey</code>) are defined, allowing endtoend integrity and confidentiality.</li> </ul> </section> <section id="structure"> <h2>Message Structure</h2> <p>A minimal UMF3 document looks like the following:</p> <pre>{ "envelope": { "messageId": "d4f9c2e5-9a6b-4c2a-8e7d-3f5a1b6c9d0e", "timestamp": "2026-05-30T12:45:00Z", "version": "3.0", "schema": "urn:example:order:1.0" }, "payload": { "orderId": "ORD-1001", "customerId": "CUST-342", "items": [ { "sku": "ABC123", "qty": 2, "price": 9.99 }, { "sku": "XYZ789", "qty": 1, "price": 24.5 } ], "total": 44.48 }}</pre> <p>When security is required, the envelope may contain a <code>signature</code> and an <code>encryptedKey</code> section:</p> <pre>{ "envelope": { "messageId": "...", "timestamp": "...", "version": "3
