AbstractReference ontologies are intended to aid domain ontology design, identify gaps and inconsistencies in representations of domain information, and facilitate data interoperability. The application of a reference ontology to the water domain is untested. We present findings from using a first-order logic reference ontology for the water domain, the Hydro Foundational Ontology (HyFO), to identify and remedy semantic gaps and inconsistencies in the Ground-water Markup Language (GWML2), a data model for groundwater information with less de-tailed formal semantics. We express GWML2 as a logical extension of HyFO, thereby im-proving GWML2's compatibility with other hydro data models. We derive general desiderata for a "good" domain reference ontology in the geosciences and discuss the benefits one can expect from their use for the ontological analysis of geoscience data models.
Summary(Plain Language Summary, not published)
The paper maps the GWML2 groundwater data standard into a logic-driven computational representation, to explore enhanced semantics and reasoning. GWML2 is the data standard used for data sharing within Canada, and between Canada and the US.
