My opinion (written before Frank's latest message): I used only about= in most of the DAML I've generated, but have come to believe that ID= is the preferred idiom (especially for Classes and Properties). ID= simplifies the naming issues and signals the author's intent that this is the "primary" definition of the object. Conversely, about= signals the author's intent that he is making an assertion about "someone else's" object. Two IDs can exist for a given URI only in the same page. A DAML Validator should issue a warning if multiple IDs exist for the same name. It should also probably suggest that about="#name" be replaced with ID="name" I think DAML+OIL should continue to support both ID= and about= and that "best practice" should encourage the appropriate use of both.
