Subject: Re: [xml-dev] Re: [ubl-dev] Top 10 uses of XML in 2007
Hi Elliotte Can any of these arguments be verified? " (Compare OpenDocument to the equivalent Microsoft Office binary, for example.)" isn't that specious? The OO file is zipped and both are XML for the main part, to varying degrees turned into binary (depending on which version of the MS office file you mean). The comparison between the unzipped ODF and the zipped ODF is the more realistic one of course. Guess which is biggest. Add to that the fact that having a type of compression which is greatly improved by the use of a schema (so you can leave out a lot of the tag characters along with the usual compression) - optimised either for performance or for space (are you telling me these optimisations are erroneous?) and you get some barely disputable facts. Which do the military forces use? Then use these extra compression technologies to improve web services too. Only question is what is the overhead in terms of performance in integrating with text-based systems - having to compress at one end and decompress at the other. Still that doesn't stop OO dealing with compressed XML. Could a browser dealing in text XML (or HTML) handle the same amount of information (data and presentation) more speedily? Isn't this all just too obvious to debate?

And the evidence you have that it will do this is what exactly? A lot of people are working under twenty year old assumptions about what is and is not fast, that haven't been true for years. Binary formats are not a magic panacea to improve performance. In many cases, XML is actually smaller than competing binary formats. (Compare OpenDocument to the equivalent Microsoft Office binary, for example.) There are a lot of myths and wild guesses about performance. I don't doubt that people who never bother to crack open an analyzer or write a good benchmark will switch to binary XML for no good reason. That's a big reason I oppose it. The only areas in which the arguments for binary XML are the least bit compelling are in the wireless space, and that has a lot more to do with battery life than document size. -- *Elliotte Rusty Harold elharo@metalab.unc.edu Java I/O 2nd Edition Just Published! http://www.cafeaulait.org/books/javaio2/ http://www.amazon.com/exec/obidos/ISBN=0596527500/ref=nosim/cafeaulaitA/ ______________________________________________________________________ Please note the new simpler name for our website: http://www.bristol.gov.uk Our email addresses have also changed - visit http://www.bristol.gov.uk/bigchange for further details.
