Import complex relations

You can import complex relations with the import functionality. For example, this is useful if you want to create a lot of complex relations in one go.

Tip 
  • For importing complex relations using an Excel file, see the knowledge base on the Collibra Support Portal.

  • If you want to edit a large amount of assets in one go, you can perform an export-import round trip:

    1. Create a view that contains all the assets and characteristics that you want to edit.
    2. Export the assets from that view.
    3. Edit the exported file.
    4. Import the assets back into the same view. Collibra automatically maps the characteristics during the import, implementing your changes.

Note 
  • Importing assets and complex relations is restricted by the file upload settings, which define the maximum file size, allowed file extensions, and maximum amount of uploads and downloads per day. Contact Collibra Support to change the file upload settings. The default maximum file size is 512 MB.
  • When importing Excel files, you may encounter an error with the file being too large. If this is the case, split the file into multiple smaller files or use CSV.
  • Importing data from a large Excel file can consume a lot of memory. We advise you to import from CSV instead of Excel, or to limit the Excel file to only contain the data you really need.

Prerequisites

  • You have prepared an Excel file for upload:
    • Only the essential sheets, columns and rows remain.
    • Numbers that have to be interpreted as text are preceded by a single quotation mark.
    • Dates are formatted as yyyy-mm-dd.
    • The related assets to connect for a single complex relation must be specified in a single cell.
    • Your import file has the correct structure to import complex relations.
  • Import using the new wizard
  • Import using the old wizard

Import using the new wizard

  1. Open a view.
  2. Above the table, to the right, click → Complex Relations.
    The Import dialog box appears.
  3. Drag and drop the file or click Upload a file and choose the appropriate Excel file for upload.
  4. Click Next.
  5. Select the Complex Relation Type from the drop down list.
  6. Manage the mapping of the fields of the import file and your Collibra resources:
    1. The Import mapping dialog box appears and Collibra tries to map the table headers in your import file to Collibra resources, based on the names of the fields and columns.

      Automap

      Button to let Collibra automatically map all table headers in the import file to Collibra resources, based on their names.

      Clear

      Button to remove all mappings.

      Mapping table

      This table enables you to map table headers in the import file to Collibra resources.

      Each row in the table has a background color to indicate whether the table header is mapped or not.

      • Green: When the table header from the import file is mapped to a Collibra resource the row will be highlighted in green.
      • Red: After clicking the warning about unmapped items these rows will be highlighted in red and moved to a separate section at the bottom of the table.

      Once a table header in the unmapped section has a mapping selected it will be moved to the green mapped section.

      You can use the Automap button to automatically map a table header, unless you have already manually changed the mapping. If you manually change a mapping then auto-mapping will not longer override this selection.

      An individual mapping can be cleared by using the cross icon in the Table Headers column.

      If a relation type in your file matches with multiple relation types in Collibra then it will not be auto-mapped, meaning you will be required to map this relation type manually. This is to avoid any incorrect mapping.

      Table HeadersThis column contains the field name of the table headers in your file.
      Collibra Resources

      This column shows to which Collibra resource the file field is mapped. If the field is unmapped then there is a drop down list with the available Collibraresources . For relations, a hierarchy is displayed.

      Complex Relation TypeSelect the complex relation type you want to use for mapping.
    2. Click Automap to let Collibra map all previously unmapped columns automatically.
    3. If required, manually map columns to another resource.
    4. Click Next.
      The Import options appear.
  7. Enter the required information.
    SettingResult
    Test importCollibra first simulates an import without affecting the data to give you an overview of how the actual import would affect the data. After the overview, you can proceed with the import, go back to change the options or cancel the import.
  8. Click the Test Import button.
    The test results appear.

  9. If the simulated results match your expectations, click Import.

    Tip If they don't, click Back to change the mapping or import options.

    The import results appear.

  10. Click Close.

Import using the old wizard

Note For the original import wizard, the max file size is restricted to 100 MB.

  1. Open a view.
  2. Above the table, to the right, click → Complex Relations.
    The Import dialog box appears.
  3. Click Select File and choose the appropriate Excel file for upload.
  4. Click Next.
  5. Select the complex relation type that you want to import.
  6. Click Next.
  7. Manage the mapping of the columns of the import file and the view's fields.
    1. The Import mapping dialog box appears and Collibra tries to map the columns from the import file with the Collibra resources, based on the names of the columns and resources.

      Mapping table

      This table enables you to map characteristics of the view to columns of the import file.

      Each row has a background color to indicate whether a characteristics is mapped or not.

      • Dark green: The characteristic is mapped to a column in the import file.
      • Light green: The relation is mapped partially. This means not all underlying fields are mapped.
      • White: The characteristic is not mapped.

      Characteristic
      		This column contains the available characteristics. Depending on the selection in the view selector, it contains either the characteristics of the selected view, or all characteristics. For relations, a hierarchy is displayed.

      Import Column

      This column should contain fields in which you can choose columns of the import file to map to a characteristic of the view.

    2. If required, choose another view in the view selector.
      Tip Choose All characteristics to show all characteristics. In most cases, this makes it easier to map all characteristics.
    3. Click Automap to let Collibra map all visible columns automatically.
    4. If required, manually map columns to another characteristic.
  8. Click Next.
