Andreas developed the Vehicle Leasing Information Model for the smart-data-models/incubated repository, expanding the existing Vehicle data model to support leasing information for municipal fleet management. He introduced a new leasingInfo property using JSON schema, enabling storage of contract details such as leasing type, dates, costs, and distance allowances. This addition allows municipalities to analyze total cost of ownership and manage leased fleets more effectively. Andreas focused on robust data modeling and API development, ensuring the schema was extensible for future analytics and dashboards. The work demonstrated a thoughtful approach to schema evolution, though it was limited in scope to one feature.
