<li>An instance of a <strong>Process Execution</strong> represents an activity that has an effect on entities, namely it either <em>generates</em> or <em>uses</em> one or more entities. Use and generation are modelled by means of the <strong>used</strong> and the <strong>wasGeneratedBy</strong> relationships. Additionally, one can use the <strong>hadParticipant</strong> relation to indicate participation of an Entity in a Process Execution. Activities may include not only computations, but also any other type of activity that can be described in terms of their effect on entities.

The assertion of an instance of an entity expression, <span class="name">entity(id, [ attr1=val1, ...])</span>, states, from a given asserter's viewpoint, the existence of an identifiable characterized thing, whose situation in the world is represented by the attribute-value pairs, which remain unchanged during a characterization interval, i.e. a continuous interval between two events in the world.

<p>Such start and end times constitute <em>attributes</em> of an activity, where the meaning of attribute in the context of a process execution expression is similar to the meaning of attribute for entity expression. A process execution expression's attribute remains constant for the duration of the activity it represents. Further characteristics of the activity in the world can be represented by other attribute-value pairs, which MUST also remain unchanged during the activity duration.</p>
