A Description is a SocialObject that represents a conceptualization. It can be thought also as a 'descriptive context' that uses or defines concepts in order to create a view on a 'relational context' (cf. Situation) out of a set of data or observations. For example, a Plan is a Description of some actions to be executed by agents in a certain way, with certain parameters; a Diagnosis is a Description that provides an interpretation for a set of observed entities, etc.
