To set up a catalog to store information in addition to fields that Cumulus supports, you can define your own custom fields.
NOTE: Same Custom Field for Multiple Catalogs If you have created a custom field for one catalog, you can easily copy this field to another catalog. If multiple catalogs are opened in the same window, Cumulus will display the custom record fields of all these open catalogs in the list of the Fields tab. You can select a custom field of another catalog and add it to the current catalog. We recommend using this way of adding the same custom field to several catalogs, as only then will the field have the same GUID (Globally Unique Identifier) in different catalogs. And only when the GUID is the same, a custom field can be used for searching in different catalogs. Another advantage is that fields of the type String List already include the entries that have been made.
With a standard Workgroup Edition you can create custom record fields only. An Enterprise Edition or an corresponding add-on product enables you to create custom category fields, too.
To add a custom field:
1. Make sure the collection window containing the catalog is the active window in Cumulus.
2. Select Cumulus / Edit> Preferences.
3. Click Catalog Settings.
The Catalog Settings window is displayed. If the active collection window contains more than one catalog, select the catalog you want to edit under Catalogs.
4. Click Record Fields or Category Fields. This displays a list of the current record or category fields included in the catalog.
5. Click the Add Field button. This brings up a dialog in which you can add a new field.
6. Click the Custom Field tab.
7. Enter a name for the field and select the type of field.
8. Click OK. The new field is added to the list of fields included in the catalog.
9. Define the field properties.
• In the list you can activate certain options – Sorting – Contain Search – User Editable: If this is not checked, the field contents cannot be modified.
• In the Field Properties dialog you can define more options for the field. Select the field’s entry in the list and click the Properties button. The options available from the Field Properties dialog depend on the field type. For details, see “Overview: Field Properties” .
10. Click OK to close the Field Properties window. This brings you back to the fields list.
11. Click Apply to save your changes.
If you want this field to be shown in a view, you have to customize the corresponding view set and add this field.
