We extended the existing author info boxes (or knowledge panels) on our item pages to include an image and short description from Wikidata.
We extended our existing author and subject browse pages to include the following data
- An image from Wikidata
- A description from DbPedia (or a description from Wikidata if the former is not available)
- Additional information for people such as citizenship, education, and pseudonyms
- The LC Classification number for the subject or author being displayed. This information is retrieved by requesting the linked data from id.loc.gov for the URI for that subject or author. This information is then used to generate a link to our call number browse using the classification.
We implemented a system whereby we can exclude information from being displayed for specific authors or subjects. Using a YAML file, we can designate whether we wish to hide all external data for an author or subject heading should be hidden, or whether we wish to hide certain properties for that author or subject heading.
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 and to query Wikidata. DbPedia queries use a combination of Wikidata QID and label searches to retrieve descriptions.
We have also incorporated library holdings search information into the author and subject pages to allow users to more easily find related information and resources.
Below, we include screenshots and links as examples, with additional explanation around how we support hiding information when needed.

- Author and subject pages
