Worked on the ocsf/ocsf-schema repository to deliver a new Resource Reference Attribute for compliance checks, enabling explicit association between each check and the resource evaluated. This enhancement improved traceability and compliance reporting by updating the check object schema and adding an optional resource field while maintaining backward compatibility. The implementation involved careful API design and backend development, with schema changes validated locally against ocsf-server to ensure error-free integration. Documentation was updated to reflect the new attribute, including detailed entries in the changelog. The work primarily utilized JSON for schema definition and data modeling, focusing on robust and maintainable schema evolution.
