Summary

Rockstar🎓
Top SchoolGordon Mackenzie is a Schema Wrangler and ontologist with over a decade of experience shaping large-scale knowledge graphs, currently doing schema design and curation at Google. He cut his teeth at Metaweb/Freebase where he combined testing, community relations, and schema development—work that foreshadowed today’s structured-data ecosystems. Comfortable bridging technical rigor and linguistic nuance, he specializes in creating, massaging, and validating types and ontologies that make data interoperable and queryable. His background in graphic design and chemistry gives him an unusual eye for information structure and a methodical approach to problem-solving. Based in Oakland, he blends hands-on editing with community-facing stewardship to ensure schemas serve both machines and human contributors. Colleagues rely on him for pragmatic schema decisions that balance technical constraints with real-world data needs.
