Concept
Digital asset management
Summary
Digital asset management (DAM) and the implementation of its use as a computer application is required in the collection of digital assets to ensure that the owner, and possibly their delegates, can perform operations on the data files.
The term media asset management (MAM) may be used in reference to Digital Asset Management when applied to the sub-set of digital objects commonly considered "media", namely audio recordings, photos, and videos. Any editing process that involves media, especially video, can make use of a MAM to access media components to be edited together, or to be combined with a live feed, in a fluent manner. A MAM typically offers at least one searchable index of the images, audio, and videos it contains constructed from metadata harvested from the images using pattern recognition, or input manually.
Applications implement digital asset management by importing it from the analog and/or digital domains (by encoding, , optical character recognition, etc.) or by authoring it as new object.
A primary function of a DAM system is to make assets easily available to its users by providing a searchable index that supports retrieval of assets by their content and/or metadata. The cataloging function is usually part of the ingestion process for new assets.
Digital assets will typically have a lifecycle, which may include various states such as creation, approval, live, archived and deleted.
Often a DAM system will store earlier versions of a digital asset and allow those to be downloaded or reverted to. Therefore, a DAM system can operate as an advanced type of version control system.
Finally, a DAM system typically includes security controls ensuring relevant people have access to assets. This will often involve integration with existing directory services via a technology such as single sign-on.
Smaller DAM systems are used in a particular operational context, for instance, in video production systems.

Digital rights management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) like access control technologies, can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification and distribution of copyrighted works (e.g. software, multimedia content) and of systems that enforce these policies within devices. DRM technologies include licensing agreements and encryption.
Enterprise content management
Enterprise content management (ECM) extends the concept of content management by adding a timeline for each content item and, possibly, enforcing processes for its creation, approval, and distribution. Systems using ECM generally provide a secure repository for managed items, analog or digital. They also include one (or more) methods for importing content to bring manage new items, and several presentation methods to make items available for use. Although ECM content may be protected by digital rights management (DRM), it is not required.
Content repository
A content repository or content store is a database of digital content with an associated set of data management, search and access methods allowing application-independent access to the content, rather like a digital library, but with the ability to store and modify content in addition to searching and retrieving. The content repository acts as the storage engine for a larger application such as a content management system or a document management system, which adds a user interface on top of the repository's application programming interface.
