Olemartinorg enhanced data quality in the Altinn/altinn-studio repository by developing a new employment status field and implementing tag validation within the data model and schema. Using C# and JSON, they updated serialization logic for nullable fields to ensure robust data exchange and backward compatibility across backend components. Their work introduced the fortsattAnsatt field to capture employment status and added a boolean property to enforce tag validation, reducing invalid metadata and improving data integrity. The changes focused on backend development, data modeling, and validation, addressing data consistency challenges and strengthening the reliability of form data and downstream processes within the platform.
