PROFILE
Martin Hammarstedt
Worked extensively on the spraakbanken/metadata repository, delivering robust solutions for metadata management, schema validation, and multilingual NLP resource configuration. Leveraged Python scripting and YAML to automate template generation, enforce schema adherence, and streamline data onboarding for linguistic datasets. Addressed data integrity by implementing regex-based date validation, correcting configuration errors, and standardizing license metadata using SPDX. Enhanced documentation and template usability, enabling reliable downstream processing and governance compliance. Focused on maintainability, the work included database schema evolution, metadata cleanup, and improved resource linking. This approach ensured scalable, high-quality metadata pipelines supporting diverse linguistic resources and efficient, reproducible data workflows.
