A similar feature has been rolled out by library technology provider Zepheira, which is creating "About Author" tools for entities represented in the collections of public libraries across the United States.62 Once linked data entities are matched against Wikidata, a much larger community of reusers can take advantage of that data for discovery applications.

Archival and Special Collections Discovery

SNAC (Social Networks and Archival Context) provides the archival community with a central hub where data about archival creators (corporations, people, and families) are maintained. In SNAC, a record is defined as a "constellation" and each constellation is assigned a unique identifier. During the creation of the SNAC database, many of these constellations were linked to library authority records as well as Wikipedia. SNAC has also benefited from those links by pulling associated images from Wikimedia Commons into its interface when a SNAC constellation is linked to a Wikipedia entry. More recently, the SNAC constellations were matched with existing Wikidata items, ARL White Paper on Wikidata: Opportunities and Recommendations
