Reasoning over knowledge graphs is traditionally built upon a hierarchy of
languages in the Semantic Web Stack. Starting from the Resource Description
Framework (RDF) for knowledge graphs, more advanced constructs have been
introduced through various syntax extensions to add reasoning capabilities to
knowledge graphs. In this paper, we show how standardized semantic web
technologies (RDF and its query language SPARQL) can be reproduced in a unified
manner with dependent type theory. In addition to providing the basic
functionalities of knowledge graphs, dependent types add expressiveness in
encoding both entities and queries, explainability in answers to queries
through witnesses, and compositionality and automation in the construction of
witnesses. Using the Coq proof assistant, we demonstrate how to build and query
dependently typed knowledge graphs as a proof of concept for future works in
this direction.
