This article explores foundational best practices and practical tips establishing metadata in AEM Assets. Metadata is crucial for managing digital assets as it makes content searchable, manageable, and reusable by providing context and categorization. It drives search, automation, personalization, and workflow efficiencies in a Digital Asset Management (DAM) system.

Getting started with metadata

In simple terms, metadata is data about your digital assets.

It describes, categorizes, and provides context to make your content searchable, manageable, and reusable. Think of metadata as the label on a physical file folder or the description tag on a video. Without it, content becomes just another file which is lost in the system.

Metadata define properties of a digital asset such as title, created date, creator, copyright information, expiration date, and more.

A previous article touched on folder structures. Folder structures answer “Where is it?” in terms of where the digital asset is stored. Metadata extends that and answers questions like - "What is this asset?" and "Who is it for?" and "Where should it be used?" and "When does it expire?"

In AEM Assets, metadata is not just informational, it's operational as well. It derives search, automation, personalization and various other aspects of running a DAM, and even drives workflow efficiencies. Because it derives search, automation, personalization, various aspects, even workflow efficiency, metadata is pivotal. Saying that metadata  is the backbone of structured content, we mean it quite literally. It's what gives content both purpose and power in a scalable ecosystem.

What we really need to find and reuse content is content that is smart, scalable and structured. Applying metadata and a taxonomy aren't just a best practice. They are mandatory - essential to scaling content operations. Without structured metadata and an intelligence system in place, what you get is content chaos.

Metadata gives your content a meaning, a context, and searchability. It is what makes content discoverable.

Metadata categories

Metadata can fall into different categories such as:

Best practices for metadata

TIP

“Organizations should agree on which metadata fields are optional and which are required. Setting a metadata schema and profile with required fields makes it easier for your authors to find assets.”

- Greg Dimeris, Product Owner, Web Content at T. Rowe Price and AEM Champion

Examples of metadata

Organizing metadata is done through the features of metadata schemas and metadata profiles in AEM Assets.

Not all metadata properties are applicable to all assets, so it makes sense that having a way to define what metadata applies to what types of assets is a helpful construct.

Metadata schemas

A metadata schema defines both the metadata properties and the page layout of the asset Properties page for assets in folders which use that metadata schema. The schemas define the interface where users view and interact with asset metadata in AEM. Metadata schemas can be applied to folders and inherited by subfolders to reduce complexity.

Metadata properties are important because the can also be used as filters in Search to drive content discoverability. If you have two metadata schemas, you can have the specific properties of interest in the search index to be surfaced in Search.

Is it a best practice to create multiple metadata schemas?

It depends on your organization and what type of data you need to store for your assets to make them findable and reusable. Different asset folders of asset file types may require different metadata schemas to support their unique content types or specific metadata properties that may only be relevant, or required, for certain assets.

Examples

An organization may use one metadata schema for product images that captures fields like Product ID, Color, and Usage Rights. Use another schema for marketing campaign assets that include Campaign Name, Region, and End Date. Use a third schema for corporate documents with fields such as Department, Version, and Approval Date. Each schema is tailored so users only see the metadata that is relevant to their asset type, improving both findability and governance.

TIP

“Don’t overcomplicate the metadata and schemas. Keep it simple - try to keep mandatory metadata properties to a minimum, visible on one tab.”

- Deepak Khetawat, Principal Software Engineer at Palo Alto Networks and AEM Champion

Metadata profiles

A metadata profile is powerful. It lets you apply default metadata to all assets within a folder. Different asset folders may require different metadata schemas to support their unique content types or important data to apply to the assets in a folder.

For instance, a folder containing files for a program "Summer Campaign 2025" could have a metadata profile that automatically applies default fields like Campaign = “Summer 2025” and Region = “North America” and Season = “Summer” to every asset uploaded, saving users from entering the same values repeatedly.

What is the main benefit of using Metadata Schemas and Profiles?

Once you create a Metadata Profile and apply it to a folder, any asset that you subsequently upload to the folder inherits the default metadata that was configured in the Metadata Profile.

TIP

"If you applied a Metadata Profile after asset(s) were already uploaded to the folder, reprocess the asset(s). This is powerful way to apply updated workflows, metadata, or renditions without reuploading assets. If there are multiple assets that need metadata updates, utilize the import and export metadata features in AEM."

- Melanie Bartlett, Partner Development Director at MRM and AEM Champion

Metadata-driven permissions

Metadata-driven permissions is a feature of AEM as a Cloud service used to allow access control decisions to be based on asset content or metadata properties rather than folder structure. With this capability, you can define access control policies that evaluate attributes such as asset status, type, or any custom property you define. See the Metadata-driven permissions article in the resources section below for more information.
