Hi, I found your post a useful comparison between the enterprise network and the internetwork, and the case you make for markup is strong. I would appreciate it though if you would clarify your final point : ... <- As syntax, markup offers that basis <- of communication <- when, and if, it is clearly understood that the semantics <- elaborated from that <- syntax will be entirely local, and different, at each autonomous <- node which <- might perform some useful process against that data. This seems to me to be suggesting that the markup itself has no semantic characteristics, in other words doesn't contain any information itself - I may be way off the mark, but I would have thought that the semantics of the markup would be anything but local to each node. Surely there will be some semantics associated with that markup, whether it is implicit in the item (which I have trouble with) or is provided by means of the citation of other resources that define the pieces of data and their relationship(s). In other words the meaning of an item will be 'universal', though communicated by the markup, and only the processing or interpretation of the item will be local to the internetwork node. Of course this may be different at different nodes - and it is likely to be the case that each node only uses a subset of the information conveyed by the item. The node can't elaborate anything new out of the item without interpreting it with reference to other information - and that will usually be greater than, and always different than, the semantics carried by the syntax itself. Cheers, Danny.
