The Asset Publisher application supports two kinds of subscriptions: RSS subscriptions and email subscriptions. To enable subscriptions, click the Asset Publisher’s Options icon and select Configuration. In the configuration window, open the Setup tab’s Subscriptions tab. There are two options: Enable RSS Subscription and Enable Email Subscription.
Enabling RSS Subscription creates an RSS feed containing links to all assets that the Asset Publisher is configured to display. A link to this RSS feed appears at the bottom of the Asset Publisher application. This option is only available when the Dynamic Asset Selection is configured.
Enabling Email Subscription adds a Subscribe link to the Asset Publisher. Users wishing to be notified of newly published assets can click on this link to be added to the subscription list. Liferay DXP periodically checks for new assets and sends emails to subscribed users informing them about the new assets. By default, Liferay performs this check every twenty-four hours.
