Data

Data represents the observed values and measurements described by the structural metadata, capturing statistical facts, dimensions, attributes, and time series that can be exchanged, analysed, validated, and processed between systems and organisations.

sdmx-core supports SDMX data processing by providing high-performance, streaming read and write capabilities, version-agnostic data models, validation frameworks, transformation utilities, and efficient handling of large-scale datasets across multiple SDMX formats and versions.
