You can publish collections (including smart collections) from the Adobe Experience Manager (AEM) Assets interface to an AEM Assets Brand Portal instance for your organization. After you publish the collection, it is available in Brand Portal.
If you make subsequent modifications to the original collection in AEM Assets, the changes are not reflected in Brand Portal until you publish the collection again. This characteristic ensures that work-in-progress changes are not available in Brand Portal. Only approved changes that are published by an administrator are available in Brand Portal.
From the AEM Assets interface, you can unpublish collections (including smart collections) that you publish to Brand Portal. After you unpublish the original collection, its copy is no longer available to Brand Portal users because it is deleted from the Brand Portal interface.
