Datasette Adds Semantic Column Types And Plugin Hook
8.1
Datasette released version 1.0a26 on 18 March 2026, adding semantic column type assignments for datasets. Built-in types include url, email and json, and plugins can register additional types using the new register_column_types() plugin hook. The change improves data presentation and enables developers to extend typing for customized UI and query behavior.
Key Points

- 2Enables richer data typing and presentation, improving UI and query interpretation for dataset consumers
- 3Allows plugin developers to extend types via register_column_types() hook, enabling customized data handling
Scoring Rationale
