Time-indexed Value in Context (TVC)
Sometimes, we need to describe scenarios in which someone (e.g., a person) has a value (e.g., a particular role) during a particular time and for a particular context. Four different things are involved in these kinds of scenarios:
- the entity having some value, e.g. a person or a document possessing a role or a status;
- the value had by someone, e.g. a role or a status;
- the time period during which the entity has that value, e.g. from April 2008 to September 2008;
- the particular context that characterises the act of having that value, e.g. being a member of an institution or an editor of a particular journal.
Thought as natural extension of the Time-indexed Situation pattern, this ontological pattern, called Time-indexed Value in Context (TVC), is able to describe these kinds of scenarios.
