Digital Media Technology

This document explores the importance of metadata in the context of digital media and technology. It delves into various standards such as TEI (Text Encoding Initiative), MARC21 (Machine-Readable Cataloging), and EAD (Encoded Archival Description), highlighting their roles in facilitating data management and retrieval. The discussion includes the concept of surrogates, explicit information structuring, and crosswalking between metadata formats. With examples and references, it aims to provide a comprehensive understanding of how metadata acts as “data about data” in digital resources.

  7. MARC21 • Machine Readable Cataloguing • A format rather than a description standard • Example:100 $a Ouida 245 $a In Maremma $c door Ouida ; uit het Engelsch door C. Baarslag 260 $a Haarlem $b Bohn $c 1882 300 $a 2 dl. $c 23 cm. 

  8. Encoded Archival Description (EAD) • Descriptions of collections: extent of collection, provenance, user instructions • Example:

  9. Aggregator sites

  10. Dublin Core • Generic descriptive terms • 15 elements: Title, Creator, Subject, Description, Publisher, Contributor, Date, Type, Format, Identifier, Source, Language, Relation, Coverage, Rights • Elements can be qualified, e.g. Title.alternative, Date.issued

  11. Crosswalking • Mapping and exporting metadata • For instance: TEI to Dublin Core TEI//tei:titleStmt/title//tei:titleStmt/tei:title/tei:persName//tei:opener//tei:date DCdc:title dc:creatordc:date

  12. Metadata as research data • Data from STCN: Histories of Elsevier Hackius, Maire
