Data provenance — Best Data Buyer

Follow the data's history

Record the source system, collection context, relevant dates and responsible team. Describe exports, joins, filtering, corrections, annotation and other changes. Keep the identity of the input and output versions alongside those steps.

A filename and modification date are not a complete history. A reviewer needs to understand which operation produced the current collection and which information may have been removed or changed.

A company data example

Suppose a company prepares a support dataset from its ticketing system. A useful record links the original export to the filtered collection, the preparation rules and the reviewed sample. It identifies how duplicate conversations and excluded fields were handled.

This gives a buyer a route to investigate an unexpected value or missing period. It does not, by itself, prove that every proposed licensing use is authorized.

Keep evidence with the delivery

Provide a version history and a short explanation of transformations with the dataset. Keep detailed internal records where appropriate, and agree which evidence the recipient needs before preparing a handoff.
