wtf is json-schema-fundamentals?

JSON Schema Fundamentals is a learning resource designed to teach people the core concepts of JSON Schema, which is a way to describe and validate the structure of data. The repository holds the example files and schemas used alongside the educational content, which may eventually become a book. The goal is to help learners grasp the foundational vocabulary and ideas so that even the trickiest parts of the topic become approachable. JSON Schema itself is a standardized way to define what a piece of JSON data should look like, for instance, which fields are required, what type of data each field should contain, and what format things like dates or email addresses should follow. This repository does not create a tool or application, it simply stores the practical examples and schemas that accompany the lessons. The audience is anyone trying to learn JSON Schema from the ground up. That might include a beginner developer working with APIs for the first time, a product manager trying to understand data contracts between services, or a founder trying to make sense of how their app validates user input. The pitch is straightforward: once you understand the language and fundamentals, everything else becomes much easier to pick up. The repository is fairly minimal at this stage. It contains the schema and example content tied to the fundamentals series, and the README notes that the project may grow into a book later. One thing to be aware of is that the content currently has no license, and all copyright is retained by the author, meaning you cannot freely copy or reuse the material without permission.
