Event
| A Context in which some act happens: for example, a person is born, a Work is Performed, a Product is released, a File is Downloaded. In an Event, some attribute is changed. In PCS the terms "Act" and "Event" are treated as synonymous (even though they are typically represented in everyday language respectively by a verb and a noun). For example, the act "Adapt" or "Adapting" is the verb of which a particular "AdaptingEvent" is an instance, and these terms are treated as interchangeable in PCS. So, for example, a permission to "Adapt" or for "Adapting" is synonymous with a permission to be the Agent in an "AdaptingEvent". Differences in tense and plurality are similarly ignored at the global level: for example, "Create", "Creates", "Created" and "Creating" are all treated as the same term whose particular tense or plurality can be determined unambiguously from its specific context. |
