John, Oops!! No John you are quite correct - my fault. Its a typo... Thanks Phil Tetlow Senior Consultant IBM Business Consulting Services Mobile. (+44) 7740 923328 "John Black" <JohnBlack@deltek .com> To Phil Tetlow/UK/IBM@IBMGB 05/01/2005 08:47 cc Subject RE: [SE] Ontology Driven Architectures This is very interesting and valuable. But I wonder about one phrase here: "> Even so, approaches like the UML are by no means perfect. > Although they are > capable of capturing highly complex conceptualisations, > current versions > are far from semantically rich. Furthermore they can be notoriously > unambiguous." Did you really mean "unambiguous"? should it be "ambiguous"? Perhaps I am misinterpreting.
