For those that have used ClearCase UCM in its glory days, would you know if the RTC SCM component hierarchy capability (track inter component dependencies and component relationship management) added in CLM v6.x onward is more or less the same as ClearCase UCM composite baseline capability introduced by IBM Rational with ClearCase v5.x onwards?

Hi Gurvinder,

Note that the article and forum entry referenced in this answer were created before composite baselines were supported in RTC, so they don't really have any information about the relationship between RTC composite baselines and UCM composite baselines.   The closest you could come to UCM composite baselines in RTC at that time were snapshots, but snapshot semantics are quite different from UCM composite baseline semantics in many important ways.   For example, an RTC snapshot only supports a two-level hierarchy, and there is no "snapshot history graph" that can be used to determine how a given snapshot is related to other snapshots.

Yes, semantically, RTC composite baselines are effectively the same as UCM composite baselines.   In particular, if anyone notices a significant differences, please post here.
