Datasette Enrichments

Datasette Enrichments is a plugin for Datasette that adds support for enriching data in different ways.

An enrichment is a bulk operation that can by applied to a set of rows from a table, executing code for each of those rows.

Potential use-cases for enrichments include:

• Geocoding an address and populating a latitude and longitude column

• Executing a template to generate output based on the values in each row

• Fetching data from a URL and populating a column with the result

• Executing OCR against a linked image or PDF file

Each enrichment is implemented as its own plugin.

The Datasette ecosystem includes a growing number of enrichment plugins. They are also intended to be easy to write.
