I am not partial to snapshot, partially because of the extensive functional usage of the term. I have always associated a snapshot with a point in time, not a duration - but this may be an incorrect association. I am open to discussing it, but my initial inclination was negative towards it. Will we use the same definition as we have been using for BOB? --Stephan On Jul 24, 2011, at 9:52 AM, "Reza B'Far" <reza.bfar@oracle.com> wrote: > I second the term "Snapshot".

Book X is an entity that represents a real world object. It can be put on a shelf, loaned to friends, damaged, and/or destroyed. It has important characteristics (condition, ownership, location, etc) that may change over the life of the book. We may want to represent the provenance of the book as a chain of ownership. >>> >>> |<----------------------------------------------------- Book X ----------------------------------------------------------------->| >>> |<!------ Book X with owner A ---->|<----Book X with owner B ---->|<---- Book X with owner A --------->| >>> >>> If a book changes ownership, is the "book with changed ownership" a different EntityInstance? A different InstantiatedEntity? I don't think what we current call a BOB is an 'instance of' anything. I think of it as a description of an entity that holds for some time period (not necessarily given) for which contextually important mutable characteristics of the the entity are held to be known. >>> >>> --Stephan >>> >>> On 7/22/2011 5:29 AM, Curt Tilmes wrote: >>>> On 07/22/2011 03:43 AM, Khalid Belhajjame wrote: >>>>> The term "Snapshot" was suggested some time ago, and it seems that >>>>> several people did like it. >>>>> We can also use the term "EntitySnapshot". >>>> >>>> Following from snapshot: >>>> >>>> EntityInstance >>>> EntityInstantiation >>>> InstantiatedEntity >>>> >>>> Curt >>>> >>>> >>>> >>> >>> >>> >> >> > >
