As part of the Program for Cooperative Cataloging (PCC) Wikidata Pilot, Wheaton College created and enhanced items related to Christian hymns, using one hymnal as the basis for a test data set for the substantial collection of hymnals in our library's special collections. Work has included modeling data for hymn texts, tunes, composers, and hymn writers; using Open Refine to reconcile data from Hymnary.org with Wikidata; and creating/enhancing Wikidata items that link to Hymnary and Library of Congress identifiers. Some data modeling difficulties have yet to be worked out.
