0.0. Suggested core Content Metadata Schema
Purpose: Enable "quality and fit" recommendations by tagging content with spiritual/formation context while remaining interoperable with standard library/digital media systems. Schema is JSON‑LD compatible for future RDF expansion.
Strategy:
· Core: 15 Dublin Core Metadata Initiative (DCMI) elements.[1][2][3]
· Qualifiers/Refinements: Expanded DCMI terms (e.g., dc:audience, dcterms:audience).[2][4]
· Supplements:
o MODS (Metadata Object Description Schema) for richer description (mods:genre, mods:audience).[5]
o Getty Art & Architecture Thesaurus (AAT) for visual/media descriptors where relevant (aat:300386858 for "religious art").[6][7]
o Custom Catholic tags (free-text or controlled vocabularies) for formation‑specific axes.
· Format: JSON object with @context for DCMI namespace. Tags are repeatable arrays.
