Bundle Envelope Schema & Typed Bundles

What you'll build

Vertical stack context: DOSFIUniversity (research) → DOSFI Academy (this course) → MeshNativeExchange (publishing & monetizing). Students progress from Learning → Building → Publishing → Monetizing. This lab specifies the bundle envelope schema in full, including typed bundle definitions and which adapter owns each metadata field. The envelope is the single contract that crosses the Transport ABI; getting the types right is the precondition for deterministic behavior. This module provides an in-depth exploration of the Bundle Envelope Schema and Typed Bundles within the DOSFI Mesh-Native ecosystem, emphasizing their architectural roles in the Transport Layer. It covers the construction, validation, and secure exchange of bundles, establishing foundational knowledge for implementing resilient and type-safe data transport among Nodes and Adapters. The lessons guide students through schema design, data handling procedures, and adherence to privacy and routing policies, culminating in a comprehensive assessment of their understanding.

Skills you'll practice

• Understand the architecture and purpose of Bundle Envelope Schema in the Mesh-Native ecosystem.
• Develop capability to create and validate Typed Bundles for secure data transport.

Before you start

• Basic knowledge of DOSFI architecture.
• Familiarity with Mesh-Native concepts and the role of Nodes and Adapters.
• Understanding of Transport Layer fundamentals in Mesh-Native.
