RDFa 1.0 Attributes

about
Specifies the subject of a relationship. If not given, then the subject is the current document.

rel
Defines a relation between the subject and a URL given by either href or resource. The subject is either specified by the closest about or src attribute, @@

rev
The same as the the rel attribute, except that subject and object are reversed.
property
Defines a relationship between the subject and either a string (if the content attribute is present) or a piece of markup otherwise (the content of the element that the property attribute is on).

content
Specifies a string to use as an object for the property attribute

href
Specifies an object URI for the rev and rel attributes. Takes precedence over the resource attribute.

resource
Specifies an object URI for the rev and rel attributes if href is not present.

src
Specifies the subject of a relationship.

datatype
Specifies a datatype of the object of the property attribute (either in the content attribute, or the content of the element that the datattype attribute is on.) By default, data in the content attribute is of type string, and data in the content of an element has type xml:Literal. If datatype="" is used, then for the RDF the element content is stripped of markup, and is of type string.

typeof
Creates a blank node, which becomes the subject, and asserts that the current element contains relationships that match the given RDF type.
