CROSSWALK:
“A crosswalk allows metadata
created by one community to be
used by another group that employs
a different metadata standard.”
Not everyone is following standards. Information is structured to meet specific users, so metadata schemes reflect those differences.
Many people agree on the standards of dublin core.
What is my point and how will I fulfill my mandate in this metadata chaos?
Follow a standards (MARC) and fund a system, a technology that will store it and provide an interface for users.
OPAC: online public access catalogs: + – $500,000 to purchase, $50,000/yr to maintain.
Eastman House uses TMS system.
INTEROPERABILITY = Different systems can communicate and share information. They do this by utilizing crosswalks. Crosswalks are multi-lingual.
Metadata can either be encoded within the object itself or outside it like in a MARC record.
Union catalogs, union databases= info that works together because the common information like a title has been identified in each metadata scheme. So a crosswalk unifies TITLE in MARC, Dublin Core etc., and links it.
CROSSWALK con’t.: Map a proprietary archive to Dublin Core. Map title, date, dimensions etc. = migrating data to a new platforms and develop an interface so that people can use it.
Data Conversion= big issue for most disciplines today.
