By the end of 2021, the toolchain will be developed as an MVP (minimum viable product) to be tested and refined further with more data partnerships. It will allow a wide range of users to interact with 3D and other types of multimedia objects and annotations, and ultimately open up new digital spaces for research, education and discourse around cultural stewardship and memory preservation without siloing knowledge. The proposed toolchain will extend the potentials of Wikimedia and Europeana GLAM initiatives, while remaining highly flexible and adaptable to individual institutional contexts and research needs. Results – in the form of open-source code repositories, workflow documentation and a public portal for requirements gathering (GitLab, 2021) – are being made available in alignment with community needs.
