This paper presents the CoinSampo demonstrator, a web application and data service created to open data on numismatic citizen finds reported in Finland between 2013 and 2023. The data has been converted to Linked Open Data (LOD) using light weight ontologies that were based on the data. The CoinSampo web application queries a knowledge graph with SPARQL, and offers users faceted search and various visualization options for data analysis. The application is aimed at researchers, heritage professionals, citizen scientists, amateur archaeologists, educators and the general public. We will also show how the underlying user interface framework can be applied to other similar data such as the finds data of the British Museum.

This paper presents the CoinSampo demonstrator, a web application and data service created to open data on numismatic citizen finds reported in Finland between 2013 and 2023. The data has been converted to Linked Open Data (LOD) using light weight ontologies that were based on the data. The CoinSampo web application queries a knowledge graph with SPARQL, and offers users faceted search and various visualization options for data analysis. The application is aimed at researchers, heritage professionals, citizen scientists, amateur archaeologists, educators and the general public. We will also show how the underlying user interface framework can be applied to other similar data such as the finds data of the British Museum.
