All of the data on the page is retrieved using dynamic lookups against external data sources to retrieve information. We also check against our configuration to see which data or authorities should show information from external sources. (This process is described in greater detail below). Currently, the author knowledge panel and author and subject pages rely on a string lookup of the authorized heading string against the id.loc.gov suggest service. This lookup returns a URI which we then use to retrieve LOC information such as the classification number and to query Wikidata. DbPedia queries use a combination of Wikidata QID and label searches to retrieve descriptions. Additionally, we have requested the inclusion of LOC identifiers or URIs within the catalog Solr indices and, in the future, we hope to be able to use that information directly instead of relying on string lookups to get LOC URIs .
The image below shows how information is being retrieved for the heading for George Eliot. Blue arrows represent queries or JSON retrieval. The gray boxes include the string heading or the identifiers. The image displays the local names for the URIs to make the image easier to read. The white boxes with black borders underneath the URIs show the properties we are retrieving for that URI.
