Any updated url released by Adobe.
Yeah, I haven't seen that URL before, and the root domain doesn't go anywhere either. I'd recommend going back to the rep you got that URL from and asking for clarification.
It is some kind of an DTM code Library. I don't know whether it is an official one or not but it is provided by adobe rep.
What is the context of this URL? Is it linked anywhere in an official capacity?
