standardnu
Standardnu is a hypothetical open standard for numeric data interchange that standardizes the representation of numeric values, uncertainty, units, and provenance across scientific datasets. It aims to improve reproducibility, data integration, and interoperability when combining data from diverse sources.
Origins and governance: Proposed by the Standardnu Initiative, a collaboration of data science, metrology, and open-data
Core features: explicit numeric types with defined precision and sign; arrays and nested records; units via
Adoption and software support: Pilot integrations exist in some data portals and projects. Libraries in several
Criticisms: Added complexity, governance concerns over the Unit Registry and uncertainty representations, performance overhead, and potential
Relation to other standards: Designed to complement JSON, CSV, NetCDF, and RDF workflows, and to integrate with
