Europeana Case Study

Europeana chose  Virtual Library of Francisco Sánchez the Sceptic as a case study of EDM, as can be seen on the EuropeanaPro website, under "EDM Case studies": The Polymath Virtual Library and EDM.

This case study is based on the use of links between the authority records of polygraphs in the Polymath Virtual Library usingMARC21.

The records are linked to each other through 5XX fields, in which the semantic relationship between them is recorded. This semantic relationship is noted thanks to the ontology of the DBpedia. Thus, if one author has influenced another, this is coded by the property http://dbpedia.org/ontology/influencedBy.

And if the author has in turn influenced another author, it is coded by means of the propertyhttp://dbpedia.org/ontology/influenced

Just as the authors are related to each other, they are also linked to the subject records to codify a person's field of activity. In this case, the relationships established by the 372 field of the MARC21 format are used.

And finally, the authors are linked, through URIs, to the most appropriate value vocabularies such asVIAF, datos.bne.es, ISNI, ORCID, etc.

For this purpose, "reconciliation of values" processes in different vocabularies have been carried out in a semi-automatic way.
