## What it is
A Go library implementing JSON Schema validation for draft-04, draft-06, and draft-07. It loads schemas and documents from files, URLs, strings, or Go types and reports detailed validation errors.

## Use cases
- validate  documents against a schema in go
- check api request payloads match a  schema
- validate config files against a  schema
- load  schema from url or file and validate
- get detailed  schema validation errors

## When to choose
- you need JSON Schema draft-04/06/07 validation in a Go project
- you want flexible loaders for JSON from files, HTTP, strings, or Go structs
- you need detailed per-error validation reporting

## When to avoid
- you need newer drafts like 2019-09 or 2020-12
- you need a maintained library with an explicit license
- you are not working in Go

## Facets

- maturity: maintenance
- function: parser, developer-tools
- domain: developer-tools, apis, backend
- platform: go, cross-platform
