Module base_metadata 

Metadata fields every entity carries regardless of type.

The loader prepends type, created_date, last_modified and appends tags to each type’s declared metadata_fields. Authors never write these in YAML — redeclaring a base key is a load-time error.

Canonical frontmatter order on write: type, created_date, last_modified, <type-specific>, tags.

Constants

BASE_KEYS

Every base metadata key. Used by the loader to reject YAML redeclarations and by JSON-Schema generation to surface the implicit fields.

Functions

is_base_key

prefix_fields

Fields that appear before any type-specific metadata on disk.

suffix_fields

Fields that appear after type-specific metadata on disk.
