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.^[1]

Advantages provided by repositories

• Common rules for data access allow many applications to work with the same content without interrupting the data.
• They give out signals when changes happen, letting other applications using the repository know that something has been modified, which enables collaborative data management.
• Developers can deal with data using programs that are more compatible with the desktop programming environment.
• The data model is scriptable when users use a content repository.
