    Searching Linked Open Data - Person Entity

    Introduction

    Primo VE uses Linked Open Data (LOD), which is structured data that utilizes Web technologies to link related information, to enable users to discover additional information regarding a person (such as an author or historical figure) and to relate it to materials provided by your library. The UI includes the following elements to enable discovery of person entities: Autocomplete Person, Person Info Card, and Person Page.

    • The information gathered from the Library of Congress (LC) and Wikidata is updated once weekly.

    • Currently, this functionality is supported in English only.

    Person Information Sources

    The sources of the person entity information are the Library of Congress Name Authority and Wikidata. If the information exists in LC, it is used. Otherwise, it is taken from Wikidata. The Person description is based on Wikipedia. The Library of Congress and Wikidata persons-related information is updated on our servers once a week. This means that materials removed by the Library of Congress or Wikidata (for any reason) is automatically removed from the Persons index within a reasonable time after the originating site makes the change.

    The match between LC and Wikidata is based on the Identifier property. For example, in LC it is the LC ID (which is taken from 010 a, z), and in Wikidata it is the LC authority ID. We use the LCNAME identifier in Wikidata for matching with LC data. We do not add Wikidata authors if they do not exist in LC.

    Person Info Card

    The Person Info Card appears at the top of the Recommendations panel on the Full Display page. It is displayed for each person entity (such as author or historical figure) that is associated with the record. Selecting the person's name in the card opens the Person page. The order of the cards in the Related Persons section is based on the following priority: 1) Creator, 2) Contributor, and 3) Subject. In the following example, the book is linked with the author and the person about which the book was written.
