About the Sigma collector

Important

The Sigma collector can be run on-premise using Docker or Jar files.

Note

The latest version of the Collector is 2.200. To view the release notes for this version and all previous versions, please go here.

Use this collector to harvest metadata from Sigma. Users can then:

  • Obtain a clear visibility into your Sigma workbooks, files, datasets, and more, ensuring data protection, control, and traceability.

  • Business decision-makers can effortlessly visualize and integrate Sigma's KPIs and metrics with data from other sources, leading to informed decisions.

  • Data analysts will have improved data trust levels as metadata for Sigma workbooks and elements (for example, titles, descriptions, authors, last updated info) are now easily accessible within data.world, giving quick and deep insight.

  • Gain valuable insight into data quality and health via a Sigma Hoot.
