Extraction

To configure metadata extraction (MDE) continue in the General Settings with the following steps:

  1. Under Extraction Settings, turn on Selective Extraction, if required. Selective extraction settings apply a filter to include or exclude a list of Sigma Workspaces.

    1. Click Get List of Sigma Workspaces to fetch the list of Sigma Workspaces.

    2. The status of the Get List of Sigma Workspaces action is logged in the Job History table at the bottom of the Settings page.

    3. Once the Sigma Workspace synchronization succeeds, a drop-down list of Sigma Workspaces will be enabled.

    4. Select one or more Sigma Workspaces to apply the filter.

    5. Check if you are using the desired filter option. Available filter options are described below:

Filter Option

Description

  1. Click Run Extraction Now to extract metadata. The status of the extraction action is also logged in the Job History table at the bottom of the page.

If you wish to automatically update the metadata in the Catalog, under Automated and Manual Extraction, turn on Enable Automated Extraction and select the day and time when metadata must be extracted. The metadata extraction will be automatically scheduled for the selected day and time.
