PROFILE
Jacob Wasserman
Over six months, Josh Wasserman enhanced the OvertureMaps/schema repository by designing and implementing schema features that improved data quality, validation, and governance. He introduced new fields such as postal_city, operating_status, and basic_category to support more accurate mailing, place classification, and categorization, using Python, Pydantic, and YAML for schema definition and validation. Josh also delivered a place taxonomy system with hierarchical categories and enforced stricter data validation for contact information. His work included Makefile scripting to streamline build automation and CI reliability. These contributions strengthened downstream data integrity and usability, reflecting a thoughtful, detail-oriented engineering approach.

Feb 1, 2026February 2026 — Focused on stabilizing the OvertureMaps/schema repository. A targeted Makefile fix removed a non-existent 'check-versions' target to ensure 'make check' runs cleanly, preventing build-time errors and reducing feedback time for schema changes. This change improves CI reliability and developer experience, enabling faster iteration on downstream features that rely on the schema changes.

Dec 1, 2025December 2025: Delivered Place Taxonomy System in OvertureMaps/schema, enabling a primary category, hierarchical taxonomy, and alternate categories. Added a corresponding Pydantic model, updated schemas, examples, and documentation for end-to-end support. Also completed supporting data validation work (baseline JSON, constraints in place.yaml) and documentation/test artifacts. Fixed several data-quality issues to improve consistency and reliability across the catalog.

Sep 1, 2025September 2025: Delivered schema-level improvements in OvertureMaps/schema that elevate data licensing governance and place-status classification. Implemented license metadata enhancements across sources and datasets, added an operating_status field to places with updated docs and examples, and completed targeted data quality fixes. These changes strengthen compliance with SPDX identifiers, improve data reliability for downstream consumers, and reduce data debt through field pruning and clearer schemas. Close collaboration with the team (including fixes from Seth) ensured robust validation and clear documentation.

Jun 1, 2025June 2025: Delivered schema-level data validation for place contacts in OvertureMaps/schema to strengthen data integrity and reliability. Implemented enforcement of non-empty contact fields (emails, phones, socials, websites) so that each place record must include at least one contact method. This change reduces downstream errors and improves the accuracy of contact data across services.
