Assets is a Digital Asset Management (DAM) tool that is fully integrated with the Experience Manager platform and enables your enterprise to share and distribute digital assets. Users across an organization can manage, store, and access images, videos, documents, audio clips, and rich media such as Flash files for use on the web, in print, and for digital distribution.
What is Digital Asset Management?
Assets provides enterprise-wide sharing and distribution of an organization’s key digital assets. Users across an organization can store, manage, and access digital assets such as images, graphics, audio, video, and documents through a Web interface (or a CIFS or WebDAV folder).
Well integrated into Experience Manager, the Assets capability lets you do the following:
- Add and share images, documents, audio files, and video files in a variety of file formats.
- Manage assets by grouping them by tags, lightbox, or stars (your favorites). Add annotations to assets.
- Find assets by searching file names, the full text of documents, and by searching dates, document type, and tags.
- Add or edit metadata information for assets. Metadata is automatically versioned together with the corresponding asset. You can import or export asset metadata.
- Perform image editing functions such as scaling and adding image filters. Import and export multiple digital assets simultaneously using a WebDAV or CIFS folder.
- Use workflows and notifications to allow joint processing and downloading of any set of assets and manage access rights to assets.
Experience Manager Assets is integrated with Experience Manager Sites
Assets is fully integrated with Sites and the functionality is available using the DAM icon. The digital assets managed within Assets repository can then be accessed via the content finder when authoring webpages.
The basic user interface is the same as that of Sites. See Overview of the Sites for full details.
Digital Asset Management versus image component
When determining whether to put an image into DAM repository or use image component, consider the image lifecycle:
- If the image has the same lifecycle as the page, use the Image Component.
- If the image has a separate life cycle, for example, if you use the image twice or outside WCM, use Assets.
What are digital assets?
An asset is a digital document, image, video, or audio (or part thereof) that can have multiple renditions and can have sub-assets (for example, layers in a photoshop file, slides in a PowerPoint file, pages in a pdf, files in a ZIP).
An asset is essentially a binary plus metadata plus renditions plus sub-assets. See the DAM Performance Guide for detailed information.
Uploading and/or editing a large volume of assets (particularly images) can impact the performance of your Experience Manager instance.
Experience Manager Assets terminology
When working with digital assets in Experience Manager, you need to understand the following terminology:
- Collection A collection of assets, either based on physical location (folder), common properties (saved search folder), or user selection (lightbox folders).
- Metadata Assets have metadata; for example, author, expiry date, DRM Information (Digital Rights Management), and so on. Metadata is under access control. Assets supports the following various common metadata schemata out of the box:
- Dublin Core: including author, description, date, subject, and so on.
- IPTC: including event, model, location, and so on.
- WCM: including page properties, On Time and Off Time, and so on.
- Tagging Assets can be tagged and classified. See Using Tags and Administering Tags.
- Renditions A rendition is the binary representation of an asset. Assets always have a primary representation - that of the uploaded file. They can have any number of additional representations that are created, for example by customized workflow steps or when an asset is uploaded. Renditions may be of a different size, with a different resolution, with an added watermark, or some other changed characteristic.
- Versions Versioning creates a snapshot of digital assets at a specific point in time. You can restore assets to previous versions. See versioning in Assets .
- Sub-assets Sub-assets are assets that make up an asset, for example, layers in an Adobe Photoshop file or pages in a PDF file. In Assets, you can manage sub-assets as you would assets.
How to work with assets
You perform an action on an asset or collection. Actions can create or modify assets, collections, and renditions. Many of the basic actions you perform on assets - upload, delete, update, save sub-assets - trigger pre-configured workflows. These are automatically turned on in Assets and are described in detail in Assets media handlers.
The tasks you can perform with these pre-configured workflows:
- save the asset in, or delete the asset from, the repository.
- extract, and save, metadata for the asset; the individual metadata items are saved as XMP.
- generate renditions and thumbnails for the asset; including automatic resizing and cropping where necessary.
- transcode the asset where necessary. For example, video for mobile and web usage is transcoded with 24 frames per second, download video with 30 frames per second. Audio for mobile and web usage is transcoded with 128 kbps, audio for download with 192 kbps.
Of course, you can apply workflows manually as well. See Assets Media Handlers for a list of default workflows.
