We are importing assets with metadata in XML-format. To retreive all necessary information out of the XML-file, we created an importer plugin to deal with .xml instead of .properties files. So far the import works fine. However, we are facing a challenging task: Within our business it's possible that we receive metadata updates for our assets (maybe even updates for the assets themselves). If that is the case, the importer simply creates new assets with new metadata in Nuxeo DAM. Is it possible to configure Nuxeo so that assets are only created when they don't exist yet? If they exist we only want their metadata being updated.

Thank you, Christian
