Compare with Wikibase tabular data model

[nichtich]

The Wikibase software supports managing tabular data. Data is mainly collected on Wikimedia Commons, for instance tables with population data.

Wikibase Tabular Data was based on Tabular Data Resource so its likely compatible with some restrictions.

Wikibase supports data types:

• number subset of Table Schema (no NaN)
• boolean same as Table Schema
• string same as Table Schema but limited to 400 characters at most and not including \n or \t.
• localized not supported by Table Schema

Special value null can always be used for missing numbers where Table Schema uses special strings.
