Starting Date: 
2010-03-26
Working Group: 
1
Status: 
Done
Closing Date: 
2010-12-20
Background: 

In the second example we read (wrote):
"The E2 Temporal Entity class is an abstract class (i.e. it has no instances) that serves to group together all classes with a temporal component, such as instances of E4 Period, E5 Event and E3 Condition State."

Current Proposal: 

Martin proposed to be changed to:
"The E2 Temporal Entity class is an abstract class (i.e. it has no direct instances) that serves to group together all classes with a temporal component, such as instances of E4 Period, E5 Event and E3 Condition State."

Vladimir has proposed to be changed to:

"The E2 Temporal Entity class is an abstract class (i.e. it may only have either indirect or inferred instances) that serves to group together all classes with a temporal component, such as instances of E4 Period, E5 Event and E3 Condition State."

Steve commented that "indirect and inferred is synonymous"

Outcome: 

The E2 Temporal Entity class is an abstract class (i.e. it has no direct instances) that serves to group together all classes with a temporal component, such as instances of E4 Period, E5 Event and E3 Condition State.

New issue: Put "abstract class" in terminology chapter.
