Detailed Description

A predicate is part of the RDF trinity: subject, predicate, object.

It is identified by URI and it defines the type of the relationship. For file metadata, a predicate can be seen as a fieldname. It has a data type, a description, a short id, a cardinality

Deprecated:

use Nepomuk::Types::Property instead

Member Enumeration Documentation

Attributes

enum PredicateProperties::Attributes

This enum is used to specify some attributes that an item can have, which fit neither in the Hint nor in the Unit enum.

Enumerator
Addable	The item or group can be added by a user.
Removable	It can be removed.
Modifiable	The value can be edited (no meaning for a group)
Cumulative	If an application wants to display information for more than one file, it may add up the values for this item (e.g. play time of an mp3 file)
Averaged	Similar to Cumulative, but the average should be calculated instead of the sum.
MultiLine	This attribute says that a string item is likely to be more than one line long, so for editing, a widget capable for multline text should be used.
SqueezeText	If the text for this item is very long, it should be squeezed to the size of the widget where it's displayed.
