cdm2arvoina

cdm2arvoina is a software project designed to facilitate interoperability between the CDM2 data model and the Arvoina data ecosystem. It provides a translation layer that maps objects, attributes, and relationships from CDM2 schemas into equivalent structures within Arvoina, enabling data to move between the two domains with traceable transformations. The project aims to reduce the complexity of manual data reformatting and to support cross-system analyses.

Key features include a configurable mapping language, reusable transformation pipelines, and a plugin-based architecture that allows adapters for common data formats such as JSON, CSV, and XML. Users define mappings between CDM2 entities and Arvoina fields, along with rules for handling nested structures, versioning, and provenance. The workflow engine can orchestrate sequential or parallel transformations, with the ability to pause, resume, and validate intermediate results. Emphasis is placed on data lineage, including transformation logs and metadata about source versions and mapping definitions.

The architecture generally comprises a lightweight core, a mapping engine, and a plugin framework. This design supports extensibility through custom adapters and community-contributed mappings. The project is typically used by research groups and organizations seeking to harmonize datasets across systems that implement CDM2 and Arvoina standards.

In practice, cdm2arvoina serves as a bridge for data integration, enabling more seamless analysis and collaboration. As with many interoperability tools, its usefulness depends on clear mapping specifications and consistent data governance. See also: Common Data Model, Arvoina data model, data interoperability.
