Each content item has a primary format. However, it is possible to represent the same document in other formats and attach it to the same object. These other formats (non-primary formats) are called renditions. Thus, it is possible to have text and pdf renditions of a document whose primary format is doc.
Note
Differences between the renditions are not limited to format, though it is probably the most common criterion; other criteria can be resolution (for images) and language (for translations).
Renditions can neither be edited nor versioned.
A rendition is not stored as a separate object within the repository. Each rendition is attached to one object representing the primary format. In fact, the only properties tied to a rendition are the object ID of the primary format and the format of the rendition itself. This is shown in the following figure:
Rendition generation can be automated by installing additional EMC Documentum software components:
