wtf is p5-json-schema?

This is a Perl library that lets developers validate data against the JSON Schema specification. In practical terms, it answers a simple question: does this chunk of JSON data match the shape and rules I expect? For example, if your application expects a JSON object with a "name" field that must be a string and an "age" field that must be a positive number, this tool checks incoming data against those requirements and tells you whether it passes or fails. JSON Schema works like a contract or template for your data. You write a schema file describing what your data should look like, and then feed both the schema and the actual data into this library. It checks each rule, such as required fields, data types, maximum lengths, or number ranges, and reports back any mismatches. This is especially useful when receiving data from web forms, APIs, or external services where you cannot guarantee the other side sent exactly what you expected. The primary audience is Perl developers building applications that handle JSON data from outside sources. A team running an internal Perl service might use this to validate configuration files before loading them, or to check API request payloads before processing them. Anyone maintaining a Perl codebase that needs to enforce data quality without writing custom validation logic for every field would find this useful. The README does not go into detail about specific features, performance characteristics, or supported versions of the JSON Schema specification. The repository appears to be a straightforward implementation focused on doing one job within the Perl ecosystem.
