JSON Schema Ecosystem Observability Platform | PoC

The JSON Schema Ecosystem Observability Platform is a data-driven monitoring and analytics system designed to track the health, adoption, and compliance of the JSON Schema ecosystem.

This Proof of Concept (PoC) demonstrates an automated observability pipeline that collects ecosystem signals from NPM, GitHub, and Bowtie validator reports, processes the data into unified metrics, detects anomalies, and visualizes insights through an interactive dashboard.

The platform transforms raw ecosystem data into actionable insights, enabling maintainers, contributors, and decision-makers to better understand the growth, stability, and compliance trends of JSON Schema implementations across the open-source landscape.
