1. A computer-implemented method, comprising: at one or more computing devices operatively coupled to a first database: obtaining export data representing a classification to be imported into the first database, the export data including information representing a set of one or more origin classifications; wherein the export data is obtained as part of other export data that represents an update to an access control list in a second database; obtaining, from the first database, first version information representing a version of the access control list in the first database after an update to the access control list in the first database; obtaining, from the other export data, second version information representing a version of the access control list in the second database after the update to the access control list in the second database; determining that the update to the access control list in the second database happened after the update to the access control list in the first database based on a comparison between the first version information and the second version information; performing a first iteration over the set of one or more origin classifications using the information representing the set of one or more origin classifications; completing the first iteration; in response to completing the first iteration, performing a second iteration over one or more origin classifications in the set of one or more origin classifications using the information representing the set of one or more origin classifications; completing the second iteration upon identifying a first origin classification, in the set of origin classifications, having a first set of one or more classification markings that, according to a translation map, can be translated to a second set of classification markings based on a classification scheme used by the database; and importing the classification into the database, the classification imported into the first database having the second set of classification markings.
