Worked on the iofoundry/ontology repository to address ontology interoperability and data integrity issues by correcting invalid IRI base URIs and updating the SKOS namespace. Focused on ensuring that supply chain and core ontologies used valid cross-references, which improved compatibility with Semantic Web standards and downstream RDF consumers. Applied ontology engineering expertise to normalize IRIs and maintain consistent namespace usage, reducing integration errors and supporting robust ontology governance. Utilized RDF and Turtle languages alongside SKOS to implement disciplined bug fixes in a production environment, demonstrating a methodical approach to maintaining high-quality, standards-compliant ontological resources for enterprise data ecosystems.
