A Medallion-Based Lakehouse Architecture and ISO/IEC 25012 Evaluation Framework for Government Open Data
Keywords:
Medallion-Based Lakehouse Architecture, ISO/IEC 25012 Evaluation Framework, Government Open DataAbstract
This study is positioned as Design Science Research (DSR) and a pre-production design study that produces two artifacts for government open data: a medallion-based lakehouse architecture and an ISO/IEC 25012-based evaluation framework. The population statistics dataset from the Department of Provincial Administration (DOPA), Ministry of Interior (MOI), Thailand, is used as a case dataset. The architecture organizes data into Landing, Bronze, Silver, Gold, and Audit layers to separate raw file preservation, source-faithful structuring, standardization, analytical modeling, and audit evidence. Open-source components, including MinIO, Apache Iceberg, Hive Metastore, PostgreSQL, Trino, Airflow, and OpenMetadata, are used to specify a reproducible lakehouse environment. The results present planned storage objects, table schemas, metadata, and quality measurement structures for transforming a headerless source file into structured and traceable lakehouse tables. ISO/IEC 25012 is used to define measurable indicators for completeness, consistency, credibility, currentness, traceability, understandability, accessibility, and compliance across lakehouse layers. Rather than reporting production deployment or empirical performance results, the study contributes an architectural and methodological foundation for future implementation and validation of transparent government open-data lakehouse pipelines.
