Instance Attribute Details

#metadata ⇒ Hash?

Sanctorale metadata.

Data files may contain YAML front matter. If provided, it’s loaded by CalendariumRomanum::SanctoraleLoader and stored in this property. All data files bundled in the gem (see Data) have YAML front matter which is a Hash with a few standardized keys. While YAML also supports top-level content of other types, sanctorale data authors should stick to the convention of using Hash as the top-level data structure of their front matters.

Returns:

  • (Hash, nil)

Since:

  • 0.7.0
