Related to our approach to represent and to query lists as composite values in RDF-based Knowledge Graphs, I developed a tool to convert RDF files in which lists are represented as RDF collections (rdf:List) into files that use our cdt:List approach. Repo: github.com/hartig/SPARQL-…

So far, declarative mapping languages for knowledge graph construction (RML and the likes) have lacked a solid formal foundation 😶‍🌫️ ⚡ Our #ESWC2025 paper changes that: We introduce an algebra for mappings, provide a formal semantics of RML, and more. 🔎 arxiv.org/abs/2503.10385
