Declarative knowledge is "knowing what": facts, definitions, taxonomies, and explicit relationships. In this wiki it is represented primarily as YAML frontmatter on markdown pages, compiled into an RDF graph via the Wiki CLI.

Examples include schema:Person fields on biography pages, schema:TechArticle metadata on guides, and typed links between entities. SHACL and JSON Schema (wazoo:jsonSchema) validate that declarative statements stay complete and consistent.

Pair declarative pages with Procedural Knowledge—workflows and commands that keep the graph correct and surfaces like indexes up to date.

# Declarative Knowledge

**Declarative knowledge** is "knowing what": facts, definitions, taxonomies, and explicit relationships. In this wiki it is represented primarily as YAML frontmatter on markdown pages, compiled into an [RDF](RDF.md) graph via the [Wiki CLI](Wiki_CLI.md).

Examples include `schema:Person` fields on biography pages, `schema:TechArticle` metadata on guides, and typed links between entities. [SHACL](SHACL.md) and JSON Schema (`wazoo:jsonSchema`) validate that declarative statements stay complete and consistent.

Pair declarative pages with [Procedural Knowledge](Procedural_Knowledge.md)—workflows and commands that keep the graph correct and surfaces like indexes up to date.
