Introduction of the notion
Source: Ceisar & Praxeme Common Glossary
As a very common term, “activity” conveys many meanings. In practice, it could lead to misunderstandings. The Praxeme metamodel distinguishes the connotations depending on the level of representation where it applies. “Activity” as a term is reserved for the level of execution, so as to comply with the broader usage. When it comes to representation, a representation or a specification of an activity is called a practice. As a result, we avoid confusion between the fact and its representation.
