Finnish Archaeological Finds Recording Linked Open Database (SuALT)

The Finnish Archaeological Finds Recording Linked Open Database (SuALT) is a multidisciplinary project developing innovative solutions to respond to metal detecting and other non-professional encounters with archaeological material, applying semantic computing to “citizen science”. The growing flow of uncovered archaeological material poses challenges to researchers and collections finds data managers. We must support finders with legislative and also archaeological information. Easy to use tools to report finds and provide structured metadata are needed. Leaving finds cataloguing to curators is increasingly unfeasible given the increase in metal detecting. To make use of new data, cultural heritage managers, researchers and the public need search and analysis tools. Since finds are connected to existing collections, we also address cross-collection data interoperability. The methods and Open Source tools developed are also applicable to other cultural heritage citizen science fields.

The key product of the project is a demonstrator, FindSampo, a semantic portal and Linked Open Data service based on the "Sampo" model and a member of the Sampo series of systems for Digital Humanities research and application.

For more details about the project, see SuALT Home Page.


Thanks for collaborations to our colleagues at the University of Helsinki and Finnish Heritage Agengy, the two other consortium partners in our project in addition to Aalto University. Our research is funded by the Academy of Finland.
