Property 'has predicate'

Property

Attributed property

has predicate

Property

This is a sligthly lighter-weight version of reification, for use with class AttributedProperty. To create a sourced statement of the form "X pred true", where pred is a boolean property, do the following: create an instance A of AttributedProperty, and add the statements "X hasAttributedProperty A" and "A hasPredicate pred". Then identify the source via "A hasSource ...". If pred is an object property or datatype property other than boolean, also add the statement "A hasObject obj".
