Learn how to edit the metadata of multiple assets and collections simultaneously to quickly propagate common metadata changes.
Adobe Enterprise Manager (AEM) Assets lets you edit the metadata of multiple assets simultaneously so you can quickly propagate common metadata changes to assets in bulk. You can also edit the metadata for multiple collections in bulk.
Use the properties page to perform metadata changes on multiple assets or collections:
To customize the metadata properties page, including adding, modifying, deleting metadata properties, use the Schema editor.
The bulk editing methods work for assets available in a folder or a collection. For the assets that are available across folders or match a common criteria, it is possible to update the metadata in bulk from asset search results.
For single-value fields, the new metadata is not appended to the existing value in the field even if you select Append mode.
To prevent DOS like situation, AEM limits the number of parameters supported in a Sling request. When updating metadata of many assets in one go, you may reach the limit and the metadata does not get updated for more assets. AEM generates the following warning in the logs:
org.apache.sling.engine.impl.parameters.Util Too many name/value pairs, stopped processing after 10000 entries
To change the limit, access Tools > Operations > Web Console and change the value of Maximum POST Parameters in Apache Sling Request Parameter Handling OSGi configuration.
