Datasets

Datasets in Captar are project-scoped collections of rows that come from either trace exports or imported files. They are meant to be an organized review surface, not a generic data warehouse. Keep each row readable enough that a reviewer can understand the example without opening half a dozen unrelated tabs.

​
Supported dataset flows

  • Export a trace into a dataset row
  • Create a new dataset inside a project
  • Import rows from json, jsonl, or csv
  • Export dataset rows back out for offline work
Each row can keep input, output, metadata, and source information such as trace ID, external trace ID, span ID, and payload retention mode.

​
When to export

  • Export traces that show the behavior you want to preserve or compare.
  • Keep representative failures, not only successful runs.
  • Avoid filling datasets with noisy duplicates.
  • Use metadata to explain why the row matters.
