Nigam, This is an interesting example... > Have an example for this one: If the instance is of a the class "Tumor" > then > on giving treatment it changes in size, shape etc, and might ultimately > disappear. On each visit we are observing a different version of the tumor > instance [in Tom]. [VK] Clearly there is a longitudinal aspect to this as the state of the tumor changes over time.... This could be modeled in two ways: Tumor1.state = X at time T1 Tumor1.state = Y at time T2 ... Tumor1.state = "Non-existent" at time Tn Essentially you are modeling state as a multivalued property or as a ternary relationship (Tumor, state, Time) Alternatively, Tumor1, v1.state = X Tumor1, v2.state = Y ... Tumor1, vN.state = "Non-existent" IMHO, the former representation conveys more information and meaning... So, it may make sense not to confound versioning with temporal progression... Look forward to the commounities thoughts on the issue.
