Vocabulary

Classes

Channel
A resource which is associated with a changing collection of items.
Feed
A resource which provides a description of one or more Channels and their associated items.
ItemTitleFeed
A Feed which provides titles but no description for its items.
Subclass of: Feed
ShortItemFeed
A Feed which provides a short description of or excerpt from its items.
Subclass of: Feed
FullItemFeed
A Feed which provides the full textual content of each item. (Very long items may still be excerpted.)
Subclass of: Feed

Note: There is no generic vocabulary for providing excerpts or complete text of items. For Posts (e.g., to message boards or weblogs), TDL defines tdl:excerpt and tdl:content, which may take a text string or XML fragment.

Properties

current
Indicates a collection of items currently associated with a Channel.
Domain: Channel
link
Indicates the primary resource with which a resource is linked.
syndicates
Indicates a Channel which this Feed describes.
Domain: Feed
Range: Channel
icon

The resources belonging to the collection indicated by “current” are called items. They do not have an associated Class, because any resource may be an item.

Format terms

For convenience, RDF Channel defines several terms which can be used to describe the format of a Feed. Typically, they would be given as the value of dc:format.
