Adobe Experience Manager Assets lets you share assets, folders, and collections as a URL with members of your organization and external entities, including partners and vendors. Sharing assets through a link is a convenient way of making resources available to external parties without them having to first login to Assets.
Edit ACLpermission on the folder or the asset that you want to share as a link.
To generate the URL for assets that you want to share with users, use the Link Sharing dialog.
/var/dam/sharelocation can view the links shared with them.
/var/dam/jobs/downloadlocation can download assets from the shared link.
In the Assets user interface, select the asset to share as a link.
From the toolbar, click the Share Link . The link that will be created after clicking Share is displayed in advance in the Share Link field. The link is not created till you select Submit.
Figure: The dialog to share assets as a link.
In the email address box of the Link Sharing dialog, type the email ID of the user you want to share the link with. You can add one or more users.
If you enter an email ID of a user that is not a member of your organization, the words External User are prefixed with the email ID of the user.
In the Subject box, enter a subject for the asset you want to share.
In the Message box, enter an optional message.
In the Expiration field, specify an expiration date and time for the link to stop working. The default expiration time for the link is one day.
To let users download the original asset, select Allow download of original file. To let users download only the renditions of the shared assets, select Allow download of renditions of file.
Click Share. A message confirms that the link is shared with the users via an email.
To view the shared asset, click the link in the email that is sent to the user. To generate a preview of the asset, click the shared asset. To close the preview, click Back. If you have shared a folder, click Parent Folder to return to the parent folder.
Experience Manager supports generating the preview of assets of only the supported file types. If other MIME types are shared, you can only download the assets and cannot preview.
To download the shared asset, click Select from the toolbar, click the asset, and then click Download from the toolbar.
To view the assets that you have shared as links, go to the Assets user interface and click the Experience Manager logo. Choose Navigation. In the Navigation pane, choose Shared Links to display a list of shared assets.
To un-share an asset, select it and click Unshare from the toolbar. A confirmation message follows. The entry for the asset is removed from the list.
On the Experience Manager home page, navigate to Tools > Operations > Web Console.
From the list of services, locate Day CQ Mail Service.
Click Edit beside the service, and configure the following parameters for Day CQ Mail Service with the details mentioned against their names:
When you download assets from the link shared using the Link Sharing feature, Experience Manager compresses the asset hierarchy from the repository and then returns the asset in a ZIP file. However, in the absence of limits to the amount of data that can be compressed in a ZIP file, huge amounts of data is subjected to compression, which causes out of memory errors in JVM. To secure the system from a potential denial of service attack due to this situation, configure the maximum size using the Max Content Size (uncompressed) parameter for Day CQ DAM Adhoc Asset Share Proxy Servlet in Configuration Manager. If uncompressed size of the asset exceeds the configured value, asset download requests are rejected. The default value is 100 MB.
Click the Experience Manager logo and then go to Tools > Operations > Web Console.
From the Web Console, locate the Day CQ DAM Adhoc Asset Share Proxy Servlet configuration.
Open the Day CQ DAM Adhoc Asset Share Proxy Servlet configuration in edit mode, and modify the value of the Max Content Size (uncompressed) parameter.
Save the changes.
Asset folders or Collections that contain a whitespace in their name may not get shared.
If users cannot download the shared assets, check with your Experience Manager administrator what the download limits are.
If you cannot send email with links to shared assets or if the other users cannot receive your email, check with your Experience Manager administrator if the email service is configured or not.
If you cannot share assets using link sharing functionality, ensure that you have the appropriate permissions. See share assets.
If a shared asset is moved to a different location, its link stops working. Re-create the link and re-share with the users.
If you want to share links from your Experience Manager Author deployment to external entities, ensure that you only expose the following URLs that are used for link sharing, for
GET requests only. Block other URLs for security reasons.
In Experience Manager interface, access Tools > Operations > Web Console. Open the Day CQ Link Externalizer configuration and modify the following properties in the Domains field with the values mentioned against
publish. For the
author properties, provide the URL for the local and the Author instances, respectively. If you run a single Experience Manager Author instance, use the same value for
author properties. For Publish instances, provide the URL of the Experience Manager Publish instance.
