Extraction

To configure metadata extraction (MDE) perform the following steps:

  1. Under Extraction Settings, turn on Selective Extraction, if required. Selective extraction settings are used to apply a filter to include or exclude one or more projects:

  2. Click Get List of Projects to first fetch the list of projects from Qlik (subject to your permissions).

  3. The status of the Get Projects action is logged in the JExtraction Job Status table at the bottom of the Settings page.

  4. Once the folder synchronization is successful, the Select Projects button is enabled - click it to see a drop-down list of projects. Select one or more (or All) projects to apply the filter.

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

Filter Option

Description

Extract all Projects except

Extract metadata from all projects except from the Folders selected.

Extract only these Projects

Extract metadata from only the selected Projects.

  1. Choose to Keep/Remove Projects not captured by your project list. When Remove Projects that are not captured by the list above is checked, all the existing Projects that are not re-extracted will be hidden from the catalog pages. Lineage and Curation data will be kept and reapplied to them after being extracted again. (Note: To permanently remove those projects’ data, the enable_soft_delete configuration flag can be adjusted - please contact Alation Support to discuss this).

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

  3. 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 to run at the selected day and time.
