On the right side panel, where additional information is displayed for authority data, the results for "persons" are empty, since there are not authority data links. https://correspsearch.net/en/search.html?e=ca6da774-7f80-427d-b9fb-78aad2854bf4&t=norkorr&x=1&w=0

Opportunities with
Linked Open Data
-
The Historical Population Register
- Opportunities
The Historical Population Register
The landing page of the Historical Population Register https://histreg.no/index.php/home (in Norwegian).
Opportunities
Source: https://histreg.no/index.php/home – using the surname Taale Andreas and the family name Gjestvang retrieves a list of hits. These persons share the same name, but may not be the same person. A key indicator is the year of birth. The displayed PFIDs are automatically assigned to each person named in an archival authority source, like the census. HBR will consolidate PFIDs into one HBR-ID for all mentions of the same person across sources.

Conclusion
- Citizen Science
