General description

Name:	Literal Reification
Submitted by:	AldoGangemi, SilvioPeroni, FabioVitali
Also Known As:
Intent:	This pattern promotes any literal as “first class object” in OWL by reifying it as a proper individual of the class litre:Literal.
Domains:	General
Competency Questions:	What is the context in which entities refer to a particular literal value? What is the meaning of a particular value considering the context in which it is used?
Solution description:	Literals are reified in proper ontological individual (belonging to the class 'Literal'), expressing the literal value they refer to through a data property. This reification allows to use each 'reified literal' as subject or object of assertions.
Reusable OWL Building Block:	1 (625)
Consequences:	This pattern allows to specify different contexts and/or meanings to a particular literal value.
Scenarios:	Modelling domains concerning descriptive tags, in which each tag may have more than one meaning depending on the context in which it is used. Extending quickly the capabilities of a model by adding the possibility to make assertions on values, previously referred through data properties, without modifying it.
