This document discusses integrating geographic linked open data to allow for interactive querying and visualization of numismatic data. It provides examples of linking numismatic concepts and coin finds to geographic data using ontologies. The goal is to enable querying numismatic objects by location and visualizing the results on an interactive map to analyze distributions of coin types and mints.
