Understand the Requirement:

The customer wants to add a field to the properties of all existing and new assets in AEM Assets to capture the asset rating.

The review team needs to fill in the ratings after the assets are uploaded.

Metadata Schemas Tool:

The Metadata Schemas tool in AEM allows you to define metadata schemas that can be applied to assets.

This tool helps in customizing the metadata forms that appear in the properties page of assets.

Create a New Schema:

To add a new property (asset rating), you need to create or update an existing metadata schema.

Navigate to Tools > Assets > Metadata Schemas in AEM.

Select the default schema or create a new schema if necessary.

Add the Rating Property:

Within the selected schema, add a new field for the rating property.

Define the field type (e.g., dropdown, text field) based on how you want the review team to input the ratings.

Configure the field properties, such as label, description, and validation rules.

Apply the Schema:

Apply this metadata schema to the folders where assets are stored. This ensures that all assets within these folders will have the new rating property.

For new assets, the rating property will appear automatically when viewing or editing properties.

Review Team Process:

After the assets are uploaded, the review team can access the properties of each asset and fill in the rating.

The rating property is now part of the asset’s metadata and can be used for sorting, searching, and filtering assets.
