A metadata schema describes the layout of the Properties page and the metadata properties displayed for assets that use the particular schema. The schema that you apply to an asset determines the metadata fields that appear on its Properties page.

Normally, the Properties page for each asset includes default metadata properties depending upon the MIME type of the asset. Administrators can use the Metadata Schema Editor to modify existing schemas or add custom metadata schemas. AEM Assets Brand Portal provides default forms for assets of various MIME types; however, you can also add custom forms for such assets.

Add a metadata schema form

To create a new metadata schema form, do the following:

  1. From the AEM toolbar at the top, click the Adobe logo to access administrative tools.

    aemlogo
  2. From the administrative tools panel, click Metadata Schemas.

    Navigation-Panel
  3. On the Metadata Schema Forms page, click Create.

    Create-metadata-schema-form
  4. In the Create Schema Form dialog box, specify the title of the Schema form, and then click Create to complete the form creation process.

    Create-schema-form

Edit a metadata schema form

You can edit a newly added or existing metadata schema form. The metadata schema form contains content derived from its parent, including tabs and form items within tabs. You can map or configure these form items to a field within a metadata node.

You can add new tabs or form items to the metadata schema form. The derived tabs and form items (from the parent) are in the locked state. You cannot alter them at the child level.

To edit a metadata schema form, do the following:

  1. From the AEM toolbar at the top, click the Adobe logo to access administrative tools.

    aemlogo
  2. From the administrative tools panel, click Metadata Schemas.

  3. From the Metadata Schema Forms page, select a schema form to edit its properties, for example, collection.

    metadata-schema-forms

    הערה:

    Unedited templates display a Lock symbol before them. If you customize any of the templates, the Lock symbol before the template disappears.

  4. From the toolbar at the top, click Edit.

    The Metadata Schema Editor page opens with the Basic tab open on the left and the Build Form tab open on the right.

  5. In the Metadata Schema Editor page, customize the Properties page of the asset by dragging one or more components from a list of component types in the Build Form tab to the Basic tab.

    metadata-schemaeditor-page
  6. To configure a component, select it and modify its properties in the Settings tab.

 

 

Components in the Build Form tab

The Build Form tab lists items that you can use in your schema form. The Settings tab provides the attributes of each item that you select in the Build Form tab. The following table lists 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 dropdown list.
Standard Tags

 Add a tag. 

Note: Administrators might need to change the path value, for example, /etc/tags/mac/<tenant_id>/<custom_tag_namespace>, if they publish the metadata schema form from AEM, where the path does not include tenant information, for example, /etc/tags/<custom_tag_namespace>.

Smart Tags  Auto-detected tags if you have purchased and configured the AEM smart tags add-on.
Hidden Field  Add a hidden field. It is sent as a POST parameter when the asset is saved.
Asset Referenced By  Add this component to view list of assets referenced by the asset.
Asset Referencing  Add to display a list of assets that reference the asset.
Asset Rating  Average rating of an asset added from AEM Assets before it is published to Brand Portal.
Contextual Metadata  Add to control the display of other metadata tabs in the Properties page of assets.

הערה:

Do not use Product References as it is not functional.

Edit the metadata component

To edit the properties of a metadata component on the form, click the component and edit its properties in the Settings tab.

  • Field Label: The name of the metadata property that is displayed on the asset's Properties page.
  • Map to Property: The value of this property provides the relative path/name to the asset node where it is saved in the CRX repository. It starts with "./" because indicating that the path is under the asset's node.

The following are the valid values for this property:

-- ./jcr:content/metadata/dc:title: Stores the value at the asset's metadata node as the property dc:title.

-- ./jcr:created: Displays the jcr property at the asset's node. If you configure these properties on view properties, we recommend that you mark them as Disable Edit, because they are protected. Otherwise, the error "Asset(s) failed to modify" occurs when you save the asset's properties.

  • Placeholder: Use this property to provide the user any relevant information regarding the metadata property.
  • Required: Use this property to mark a metadata property as mandatory on the Properties page.
  • Disable Edit: Use this property to make a metadata property uneditable on the Properties page.
  • Show Empty Field In Read Only: Mark this property to display a metadata property on the Properties page even if it has no value. By default, when a metadata property has no value, it is not be listed on the Properties page.
  • Description: Use this property to add a short description for the metadata component.
  • Delete icon: Click this icon to delete a component from the schema form. 
delete_icon_editmetadataschemaform

הערה:

All the metadata fields are read-only in the metadata editor form of an asset. Since metadata of the asset must be edited in AEM Assets before an asset is published to Brand Portal.

Add or delete a tab in the schema form

The default schema form includes the Basic and Advanced tabs. The schema editor lets you add or delete a tab. 

add_delete_tabs_metadataschemaform

Click + to add a new tab on a schema form. By default, the new tab has the name "Unnamed-1." You can modify the name from the Settings tab.

add-tab-metadata-form

Click x to delete a tab. Click Save to save the changes.

Apply a metadata schema to a folder

Brand Portal allows you to customize and control the metadata schema so that the Properties page of an asset displays only the specific information you choose to reveal. To control the metadata displayed in the Properties page, remove the required metadata from the metadata schema form and apply it to the specific folder.

To apply a metadata schema form to a folder, do the following:

  1. From the AEM toolbar at the top, click the Adobe logo to access administrative tools.

    aemlogo
  2. From the administrative tools panel, click Metadata Schemas.

  3. From the Metadata Schema Forms page, select the schema form that you want to apply to an asset, for example, clothing.

    apply-metadata-schema-form-to-folder
  4. From the toolbar at the top, click Apply to Folder(s)

  5. From the Select Folder(s) page, navigate to the folder to which you want to apply the clothing metadata schema, for example, Gloves.

    apply_metadata_schemaformtofoldergloves
  6. Click Apply to apply the metadata schema form to the folder.

    The metadata available in the clothing metadata schema form is applied to the Gloves folder and visible in the Properties page of the folder.

    folder_metadata_properties

הערה:

If you apply a schema that includes nested schemas to a folder containing video files, metadata properties for the video files may not render properly. To ensure the metadata properties render correctly, remove the nested schemas and apply only the parent schema to the folder.

Delete a metadata schema form

Brand Portal lets you delete custom schema forms only. It does not let you delete the default schema forms/templates. However, you can delete any custom changes in these forms.

To delete a form, select a form and click the Delete icon.

delete_icon_metadataschemaeditorform

הערה:

After you delete the custom changes made to a default form, the Lock symbol reappears before the form name on the Metadata Schema interface to indicate that the form is reverted to its default state.

Schema forms for MIME TYPES

Adding new forms for MIME types

In addition to the default forms, you can add custom forms for assets of various MIME types, or create a new form under an appropriate form type. For example, to add a new template for the image/png subtype, create the form under the "image" forms. The title for the schema form is the subtype name. In this case, the title is "png."

Using an existing schema template for various MIME types

You can use an existing template for a different MIME type. For example, use the image/jpeg form for assets of MIME type image/png.

In this case, create a new node at /etc/dam/metadataeditor/mimetypemappings in the CRX repository. Specify a name for the node and define the following properties:

Name Type Value
exposedmimetype String image/jpeg
mimetypes String[] image/png
  • exposedmimetype: Name of the existing form to be mapped 
  • mimetypes: List of MIME types that use the form defined in the exposedmimetype attribute

Brand Portal maps the following MIME types and schema forms:

Schema Form MIME types
image/jpeg image/pjpeg
image/tiff image/x-tiff
application/pdf application/postscript
application/x-ImageSet Multipart/Related; type=application/x-ImageSet
application/x-SpinSet Multipart/Related; type=application/x-SpinSet
application/x-MixedMediaSet Multipart/Related; type=application/x-MixedMediaSet
video/quicktime video/x-quicktime
video/mpeg4 video/mp4
video/avi video/avi, video/msvideo, video/x-msvideo
video/wmv video/x-ms-wmv
video/flv video/x-flv

The following is a list of default metadata properties:

  • jcr:content/metadata/cq:tags
