Maintenance - Clean resources

In the database the "Resource" table holds the general resource data, e.g. copyright information, and links the resource to the target entity. The "ResourceVariant" table holds the link to the resource and allows to associate several links with distinguished quality levels to a single resource. To find resource entries that are not associated with any resource variant ("empty resources"), select the Update resource data tab and choose the tab Clean empty resources.

Select the Resource target ("Description", "Descriptor", "Categorical state" or "Descriptor tree node") and the Project. Click on Check for empty resources and all resource links of the specified type will be listed where no resource variants are present in the database (see image below).

You may select or deselect all entries of the result list for the database update by clicking the buttons Select all rsp. Select none. To delete the selected resource entries from the database click on the button. Instead of updating the selecting entries you may click Close form and check list in database to return to the main program with the corresponding data sets.

You may open a table editor for the selected resources by clicking the Open table editor button (see image below).
