Bringing Clarity to Event Streams: Enabling Analytics and AI Through Rich Metadata
#1about 3 minutes
The problem of ambiguous data without clear context
Examples with LLMs demonstrate how data without metadata, like temperature units, leads to inconsistent and unreliable interpretations.
#2about 5 minutes
Using schemas to provide necessary data constraints
Providing a schema with explicit constraints and descriptions, such as units, enables LLMs to interpret data correctly and generate consistent results.
#3about 1 minute
Adopting a schema-first design for data structures
Data schemas should be created first and be independent of code assets, allowing code generation for polyglot applications and improving LLM performance.
#4about 3 minutes
Standardizing event structure using CNCF CloudEvents
Using a standard like CloudEvents provides a consistent envelope for events, preventing the chaotic and varied structures that LLMs might otherwise generate.
#5about 5 minutes
Automating client code generation with detailed metadata
By providing a comprehensive metadata document that includes endpoint and protocol details, LLMs can automatically generate complete and correct client code for publishers.
#6about 2 minutes
Moving beyond tribal knowledge in event pipelines
Current event pipelines often rely on informal communication, but a metadata-driven approach creates a formal contract that improves maintainability and compatibility.
#7about 6 minutes
A practical metadata-driven pipeline with Microsoft Fabric
A real-world example processing USGS water data demonstrates how a complete metadata definition using X Registry enables automated tooling and contract enforcement.
#8about 2 minutes
Introducing JSON Structure as a better schema language
JSON Structure is proposed as a stricter alternative to JSON Schema, designed as a data definition language with a better type system and namespace support.
#9about 4 minutes
Key standards for modern event-driven architecture
A summary of three key open standards—CloudEvents, X Registry, and JSON Structure—that provide the tools for building robust, metadata-driven systems.
