Worked on the tetherless-world/ontology-engineering repository, delivering a focused ontology refactor aimed at improving data quality and maintainability. The effort centered on updating the WhenToGoWhere properties, clarifying definitions, and refining labels while introducing boolean value restrictions for hasAccessibility and hasTrailHead. This approach enhanced data representation and enabled stricter validation, resulting in more reliable SPARQL queries for downstream consumers. The work was implemented using OWL and RDF, leveraging ontology engineering best practices. Additionally, repository hygiene was maintained by documenting a no-op commit to ensure clarity in the project’s history and to support future maintainability and transparency in ongoing development.
