Adobe Experience Manager (AEM) Assets lets you create metadata schemas for asset folders, which define the layout and metadata displayed in folder properties pages.
You can edit a newly added or existing metadata schema form, which includes the following:
- Tabs
- Form items within tabs.
You can map/configure these form items to a field within a metadata node in the CRX repository. You can add new tabs or form items to the metadata schema form.
The Build Form tab lists form items that you use in your folder metadata schema form. The Settings tab displays the attributes for each item that you select in the Build Form tab. Here is a list the form items available in the Build Form tab:
Component Name |
Description |
Section Header |
Add a section heading for a list of common components. |
Single Line Text |
Add a single-line text property. It is stored as a string. |
Multi Value Text |
Add a multi value text property. It is stored as a string array. |
Number |
Add a number component. |
Date |
Add a date component. |
Dropdown |
Add a drop-down list. |
Standard Tags |
Add a tag. |
Hidden Field |
Add a hidden field. It is sent as a POST parameter when the asset is saved. |
To edit the properties of form items, tap/click the component and edit all or a subset of the following properties in the Settings tab.
Field Label: The name of the metadata property that is displayed on the properties page for the asset.
Map to Property: This property specifies the relative path of the node in the CRX repository where it is saved. It starts with "./", which indicates that the path is under the folder's node.
The following are the valid values for this property:
- ./jcr:content/metadata/dc:title: Stores the value at the folder's metadata node as the property dc:title.
- ./jcr:created: Displays the JCR property at the folder's node. If you configure these properties in CRXDE, Adobe recommends that you mark them as Disable Edit, because these are protected. Otherwise, the error 'Asset(s) failed to modify' is generated when you save the asset's properties.
To ensure that the component is displayed properly in the metadata schema form, do not include a space in the property path.
JSON Path: Use it to specify the path of the JSON file where you specify key-value pairs for options.
Placeholder: Use this property to specify relevant placeholder text regarding the metadata property.
Choices: Use this property to specify choices in a list.
Description: Use this property to add a short description for the metadata component.
Class: Object class the property is associated with.
You can delete folder metadata schema forms from the Folder Metadata Schema Forms page. To delete a form, select it and tap/click the Delete icon from the toolbar.
You can assign a folder metadata schema to a folder either from the Folder Metadata Schema Forms page or when creating a folder.
If you configure a metadata schema for a folder, the path to the schema form is stored in the folderMetadataSchema property of the folder node under ./jcr:content.
You can assign a folder metadata schema when creating a folder. If at least one folder metadata schema exists in the system, an extra list is displayed in the Create Folder dialog. You can select the desired schema. By default, no schema is selected.
Open the properties for a folder configured with a folder metadata schema. A Folder Metadata tab is displayed in the folder properties page. To view the folder metadata schema form, select this tab.
Enter metadata values in the various fields and tap/click Save to store the values. The values you specify are stored in the folder node in the CRX repository.
