## What it is
The official Schema.org repository containing the collaborative vocabulary schemas, examples, and supporting software used to publish schema.org. It defines shared structured-data markup types for describing entities like products, events, and organizations on the web.

## Use cases
- add structured data markup to a website for SEO
- find the right schema.org type for a product or event page
- generate JSON-LD structured data for rich snippets
- look up schema.org property definitions and examples
- propose or contribute new vocabulary terms
- validate and understand microdata and RDFa vocabularies

## When to choose
- you need the canonical schema.org vocabulary definitions or release history
- you want to contribute proposals or fixes to the schema.org vocabulary
- you need reference examples of JSON-LD, microdata, or RDFa markup

## When to avoid
- you need a runtime library to parse or validate structured data in your app
- you just want to browse the vocabulary - use schema.org directly
- you need an SEO tool rather than the vocabulary source itself

## Facets
- artifact type: dataset
- maturity: active
- function: documentation, serialization, developer-tools
- domain: web-development, apis, documentation
- platform: cross-platform
- tags: structured-data, json-ld, rdf, seo, semantic-web, vocabulary, microdata, search, web-server
