A collection created in one of the two tools remains, once the items that belong to it are imported or exported, a collection in the other tool.
However, the two tools don’t offer quite the same possibilities concerning the organization of collections: in NAKALA, it is possible to create collections and sub-collections. In contrast, in Omeka, it isn’t possible to create hierarchies. As a result, the collection tree put in place in NAKALA can’t be preserved in Omeka. Thus, a collection and its sub-collection in NAKALA will become two collections of the same level in Omeka. Conversely, when exporting a collection created in Omeka, it will be necessary to indicate the parent collection in NAKALA (select “All data” for a first-level collection).
