This workshop will present a workflow for structuring and annotating multimedia datasets within a collaborative, linked open data environment. Participants will be able to take part in practical demonstrations and provide feedback on the Semantic Kompakkt toolchain that connects three existing open source software tools: 1) OpenRefine – for data reconciliation and batch upload; 2) Wikibase – for linked open data storage; and 3) Kompakkt – for rendering and annotating 3D models, and other 2D and AV media files. This toolchain was developed in the context of NFDI4Culture with a particular focus on increasing interoperability and data reuse across different domains of cultural research.
