datanvaihdon

Datanvaihdon is a Finnish term for data exchange, referring to the processes, infrastructures, and agreements that enable the transfer and sharing of data between organizations, individuals, or software systems. It encompasses collecting, transforming, distributing, and reusing data while aiming to preserve quality, privacy, and security. Datanvaihdon is applied in the public sector, private sector, research collaborations, and cross-border initiatives.

Key components include data providers and recipients, common data formats and standards, metadata and data models, and governance arrangements governing access, use, retention, and responsibility. Interoperability is a central goal, supported by shared ontologies and harmonized metadata.

Mechanisms and architectures vary, ranging from point-to-point connections to centralized data platforms and federated networks. Technologies commonly used are APIs (REST, GraphQL), data feeds, message queues, and batch file transfers. Data may be transformed to fit common schemas through ETL/ELT processes or data virtualization. Real-time or near-real-time exchange is increasingly supported by streaming technologies.

Standards and governance play a crucial role. Plain data formats such as JSON, XML, and CSV are frequently used, alongside domain standards like HL7 FHIR in healthcare or ISO 20022 in finance. Data governance, privacy and consent management, access controls, and regulatory compliance (for example, GDPR) are integral to responsible Datanvaihdon.

Benefits include improved efficiency, better decision-making, and the enabling of new services and collaborations. Challenges involve maintaining data quality, achieving semantic alignment, managing access and consent, protecting privacy, and addressing data sovereignty and security concerns.
