This document is about providing a standardized way of (fuzzily) matching a column in one dataset to a column in another dataset.

This is called “reconciling”.

Refine API

There is one obvious candidate standard, the reconciliation API used by Google Refine.

Refine essentially assigns a score integer value to each reconciliation match. The boolean key match can also be added to signify responses that have a high level of confidence.

To implement a reconciliation API you basically need a full text index (most already return weighted match values that can be returned as the score in a reconciliation API)
