Worked on schema-based integration for FMK 1.4.x by updating and publishing WSDL and XSD files in the trifork/fmk-schemas repository. Delivered the XUA WSDL for fmk-1.4.6.E6 and updated the FMKDetail XSD, ensuring versioned, stable contracts for downstream integrations. Focused on clear schema definition and repository hygiene, maintaining alignment with versioning conventions and documentation standards. Used XML and XSD to define and manage web service interfaces, reducing integration effort and supporting smoother upgrades. Emphasized traceable, auditable changes through detailed commit messages and release-note driven publication, improving integration reliability and reducing maintenance overhead for future FMK releases.
