What is a data object?
In a Fedora repository all data are managed as digital objects. A data object is a particular kind of object that represents one unit of content in the repository, which can be made up of any number of components of content and metadata as datastreams. The repository manages data objects as the representation of files stored in its own file system or referenced from other locations. It presents an abstract view of the files to applications, either as a simple abstract address for each one that hides the location of the actual data, or as a set of behaviors that present virtual views of the content and various transformation of it.

What is a persistent identifier?
Each object in a Fedora repository has a formal identifier that is unique within the repository and that has been abstracted from the location or identification of any one of its components. This persistent identifier (PID) can be generated at the time of creation of the object by the repository software or provided by the user. For more information go here.
