  Wikibase -- which is the software underlying Wikidata -- is a powerful
platform for knowledge graph creation and management. However, it has been
developed with a crowd-sourced knowledge graph creation scenario in mind, which
in particular means that it has not been designed for use case scenarios in
which a tightly controlled high-quality schema, in the form of an ontology, is
to be imposed, and indeed, independently developed ontologies do not
necessarily map seamlessly to the Wikibase approach. In this paper, we provide
the key ingredients needed in order to combine traditional ontology modeling
with use of the Wikibase platform, namely a set of \emph{axiom} patterns that
bridge the paradigm gap, together with usage instructions and a worked example
for historical data.
