Bopomofo CSVW Metadata for All 37 Zhuyin Symbols

A machine-discoverable table contract for data catalogs, ETL pipelines, RDF tooling and reproducible language-data workflows.

Download and discover

The metadata uses the standard <CSV URL>-metadata.json name and sits beside the CSV, so CSVW-aware tools can discover it directly.

Validate with a CSVW processor

The pinned command checks metadata syntax, column names, datatypes, required values, URI templates, the primary key and every row.
