# Catalog
The catalog defines global metadata used across documentation builds.
- **[products.yml](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/3943/documentation/catalog/products)** — the product catalog: identifiers, display names, and feature flags
- **[related-learning.yml](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/3943/documentation/catalog/related-learning)** — named learning destinations for the `{related-learning}` directive
- **[versions.yml](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/3943/documentation/catalog/versions)** — versioning schemes that tie products to version sets
- **[search.yml](https://docs-v3-preview.elastic.dev/elastic/docs-builder/pull/3943/documentation/catalog/synonyms)** — search synonyms and query rules for the Elasticsearch exporter
