About MIME types

Some objects have an associated Multipurpose Internet Mail Extension (MIME) type. MIME is a standard protocol for identifying the data type of a file. For a Content Platform Engine object, the MIME type identifies the type of content that is associated with the object. The MIME type allows you to manually or programmatically determine the appropriate application for displaying or editing the content. You can also use the MIME type of a newly added document as a means for automatically selecting a class for the document.

The following objects have an associated MIME type:

After you check in a document, you cannot change the value of any MIME type property associated with the document. Specifically, the Content Type and MIME Type properties become read-only on the following objects: the checked-in document, any annotations associated with the document, and any content elements that belong to the document or associated annotations. Conversely, before or during document check-in, you can assign a MIME type to those objects. An explicit MIME type assignment prevents or overrides the default MIME type assignment performed by Content Platform Engine.

Default MIME type assignment

When you check in a document, Content Platform Engine potentially assigns a default MIME type to the following objects:

No default MIME type is assigned to content reference elements. Document check-in fails with an error if the document has one or more content reference elements with no MIME type.

Content Platform Engine potentially assigns a default MIME type to a document, annotation, or content transfer element. Before document check-in, an application can also potentially assign a MIME type. From an application point of view, these application-supplied MIME types are default MIME types. Specify the MIME type directly to avoid the possibility of Content Platform Engine or an application assigning an incorrect MIME type by default. (The application in question might be a custom application.)

When you use the Create New Document wizard, MIME types are assigned to the following objects:
