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.

I just saw that DBLP (@dblp.org) has recently started to provide a public query service for everyone to run SPARQL queries over their database with information about computer science publications. Each author page includes links to relevant example queries. Very nice!
