Registrants can update anytime the metadata associated to their ISAN. This is required for In-development ISAN before activation and useful for active ISAN to add for example a new alternate title when the content is distributed in a new country.
Note: a registrant cannot update the metadata associated to an ISAN registered by another registrant. However registrants can ask to their registration agency for updates if there is a mistake or a missing information.
