The aim of the tagging ontology is to represent a tagging action, i.e the action performed by an agent that attaches a label or something with a well-defined semantics (eg. a concept or a frame etc.) to some entity.
<b>Example of Usage</b>
We provide an example of usage of the Tagging ontology for specifying the following scenario.
<b>Scenario</b> annotating a picture about the birthday of his patient John.
This picture was takes at John's 51st birthday on January 20 1971.
