We all know that Linked Data needs links to shared definitions for places, person, topic, events, and so on. At the Dutch Digital Heritage Network (NDE) we developed a finding aid which helps data maintainers to quickly find URIs for the strings in their data. This generic tool, the Network-of-Terms, uses SPARQL to search real time for relevant definitions in multiple sources. It offers a GraphQL API for implementation in registration systems and a Reconcilation API for bulk processing. It is already implemented in a number of commercial and open source applications.
