The document summarizes a presentation on using a knowledge graph to represent artifacts from multiple collections. It describes representing artifacts, their components, and relationships to events, places, and concepts as abstract fundamental categories and relationships. Searching can be done over these relationships rather than SPARQL queries. The approach aims to integrate materials analysis and 3D models of artifacts into the knowledge graph to allow richer descriptions and searching over sets of related artifacts. Challenges include attaching analysis to shards, enabling search over enriched descriptions, and representing sets such as artifact families and potential re-assemblies across collections.
