Metadata

In the 21st century, metadata typically refers to digital forms, but traditional card catalogs contain metadata, with cards holding information about books in a library (author, title, subject, etc.).

Metadata can come in different layers: This physical herbarium record of Cenchrus ciliaris consists of the specimens as well as metadata about them, while the barcode points to a digital record with metadata about the physical record.
