This topic alphabetically lists the properties that apply to the ContentReference class.
Specifies, in URL format, the name of the resource that contains the content data represented by this ContentReference object.
Specifies the Multipurpose Internet Mail Extensions (MIME) format string of the content data
carried by this content element, indicating the kind of data this content element represents.
MIME is a communications protocol that allows for the transmission of data in many forms, such as audio, binary, or video.
You can set the ContentType property of a specific content element
when you create it and attach it to a document version. The ContentType property requires a value.
If you do not provide a value for the ContentType property of a ContentReference object,
an error occurs. By contrast, if you do not provide a value for the ContentType property of a
ContentTransfer object, the Content Platform Engine attempts to discover the MIME type of the content data,
and automatically sets the property to an estimated MIME type value.
However, it is not always possible for the Content Platform Engine to make a correct determination of the content data
that the ContentTransfer object holds.
Therefore, IBM recommends that you always set this property to the correct MIME type value when you
add the content element. At a minimum, if you do not specify the MIME type value of the ContentType
property, ensure that the path specified by the RetrievalName property of the ContentTransfer
object contains the correct filename extension for the type of content data.
Although the Content Platform Engine does not enforce the format of this property's value,
a MIME format string consists of a content type, a content subtype, and an optional parameter
in the following format: "content type/subtype[;parameter]", for example, "text/html".
Interpretation of the value is up to retrieving applications.
MIME defines the following content types:
- text: Represent textual information in a number of character sets. A charset parameter may be used
("text/plain;charset=us-ascii", for example). Some subtypes: plain, html, richtext.
- image: Represents still images. Some subtypes: jpeg, gif.
- audio: Represents audio or voice data. Some subtypes: wav, au.
- video: Represents video data or moving-image data. Some subtypes: mpeg, mp4.
- message: Encapsulates an entire formatted message. Some subtypes: rfc822, partial, external-body.
- multipart: Combines several body parts of potentially different types and subtypes. Some subtypes: mixed, alternative, parallel, digest.
- application: Represents application data (such as executables) or binary data.
The following MIME types are specific to FileNet:
- application/x-filenet-declarerecordtemplate: Record template.
- application/x-filenet-external: An object that contains a single
ContentReference content element.
- application/x-filenet-external-is: External Image Services document.
- application/x-filenet-publishtemplate: Publish template.
- application/x-filenet-scenariodefinition: Scenario definition document.
- application/x-filenet-search: Stored search.
- application/x-filenet-searchtemplate: Search template.
- application/x-filenet-workflowdefinition: Workflow definition document.
A unique sequence number for a content element in a particular document or annotation version.
Server-generated, the number serves as an unchanging identity for the content element.
For annotations, on which you can change content, the element sequence number for a
content element will not change. For example, if you were to change a content element's relative position
within the list of content elements, the element's sequence number would be retained.
Or if you were to replace the first content element with updated content, the content element
would receive a new element sequence number. Element sequence numbers are not reused.
This property can be accessed from a ContentElement-based object,
or from GetContentEvent, representing the event fired when the
content element specified in this property is retrieved.
For CmVerityIndexRequest, this property is deprecated.
