Annotation Type rdf

@Retention(value=RUNTIME)
@Target(value={TYPE,CONSTRUCTOR,METHOD,FIELD,PARAMETER})
public @interface rdf

An annotation to annotate classes, methods and arguments with a uri which is meant to be interpreted as:

• for a class: the rdf:type of the class
• for a method: the relation between an instance of the class and the argument(s) of the method. If the method takes a number of argument then it relates the ordered list of those arguments.
• for an argument: the name of a relation between an instance of a class and that value of the argument
• for a field: the field is thought of as a relation between an instance of the class and the value of the field

The value must a full URI, by default it is owl:sameAs ie, the identity relation. If it is the inverse of the relation that is intended, set inverse to true. Created by Henry Story Date: Aug 28, 2005 Time: 11:51:43 PM

Element Detail

value

public abstract java.lang.String value

the String must be a full URI The URI is the name of the relation (or of the inverse of the relation in inverse() is true There is no default value. There has been discussion that if a namespace value was set on the class or package then then no value could mean that ns+name_of_variable is the URL. This would cause problems for refactoring. Someone changing the name of a variable would change the name of the relation, which may not be what is expected.

inverse

public abstract boolean inverse

Returns:

true if it is the inverse of the named relation (value()) that this relation represents

Default:

false

range

public abstract java.lang.String range

Returns:

the range uri (for literal types). Value is "" for default.

Default:

""
