At the same time, historical sources are often difficult to process automatically, which makes manual processing by researchers and wider stakeholder groups highly necessary. Follow-up work on the project might focus on developing additional participatory activities to enhance the historical data sources in a playful and educational fashion. This could also include further research on how any data collected from a non-expert audience can be processed and aggregated to improve the original sources in a reliable way. These activities would serve a twofold purpose: improve the quality of digital copies of fragile historical items for long-term preservation, and increase their visibility and use for educational purposes and public cultural awareness.
