korttitiedoille

Korttitiedoille is a term in information science referring to a compact metadata descriptor designed to accompany cards—whether traditional index cards, trading cards, or digital card representations—in catalogs and databases. It provides a standardized, machine- and human-readable summary of key information about a card item, enabling efficient indexing, search, and interlinking across systems.

The data model typically includes fields such as id, title, creator, date, type, subject or keywords, language, format, extent or version, location or repository, rights, and notes. Optional extensions may cover provenance, edition history, relationships to related items, and links to digital copies. Representations can be produced in structured formats such as JSON-LD or RDF, and can be serialized in compact text forms for local card catalogs. The goal is to support interoperability between libraries, archives, and collections while remaining simple enough for manual entry.

Historically, korttitiedoille arose from librarian and museum information projects seeking a middle ground between traditional card catalogs and full MARC or Dublin Core records. It has remained less formal than major standards but serves as a practical reference model in experimental catalogs, gaming databases, and teaching contexts about metadata design.
