Explanation on Annotation Properties

Annotation Properties

In OWL, Annotation Properties are non-logical properties that connect individuals, classes, ObjectProperty, other annotation properties etc with other object or with literal values. Technically, it connects the IRI of these entities.

The non-logical aspect means they are ignored for reasoning purposes.
They are primarily used for metadata: labels, definitions, synonyms, attribution, notes and comments, etc.

Annotation Properties in the OEO

Alternative Term

In the OEO, we don't follow the definition strictly. We use alternative term for synonyms and ambiguous terms as well.
See: Handling-ambiguous-terms

Mathematical Expression

It describes the class with a mathematical formula in LaTeX syntax.
We decided to use CamelCase for all variables in the expression. Underscores and backslashes must be avoided.

Example: "GrossNationalElectricityConsumption = GrossElectricityGeneration + ElectricityImports - ElectricityExports"
