I think we’re at the early stages of a fundamental shift in the nature of computing, which is going from something that people and businesses had to supply locally, through their own machines and their own installed software, to much more of a utility model where a lot of the computer functions we depend on are supplied from big, central stations, big central utilities over the Internet.

At the onset of XML four long years ago, I commenced a jeremiad against Standard Data Vocabularies (SDVs), to little effect. Almost immediately after the light bulb moment -- you mean, I can get all the cool benefits of web in HTML and create my own tags? I can call the price of my crullers <PricePerCruller>, right beside beside <PricePerDonutHole> in my menu? -- new users realized the problem: a browser knows how to display a heading marked as <h1> bigger and more prominently than a lowlier <h3>. Yet there are no standard display expectations or semantics for the XML tags which users themselves create. That there is no specific display for <Cruller> and, especially, not as distinct from <DonutHole> has been readily understood to demonstrate the separation of data structure expressed in XML from its display, which requires the application of styling to accomodate the fixed expectations of the browser. What has not been so readily accepted is that there should not be a standard expectation for how a data element, as identified by its markup, should be processed by programs doing something other than simple display.

There have also emerged a few "horizontal" data vocabularies, intended for expressing business communication in more general terms. One of these is the eXtensible Business Reporting Language (XBRL), about which more below. Most recently, governments and governmental organizations have begun to suggest and eventually mandate particular SDVs for required filings, a development which expands what troubles me about these vocabularies by an order of magnitude.

"But it always makes sense to look at the security implications, the value back to the customer, and those kind of issues." The DOT's ban on Vista, Internet Explorer 7, and Office 2007 applies to 15,000 computer users at DOT proper who are currently running the Windows XP Professional operating system. The memo indicates that a similar ban is in effect at the Federal Aviation Administration, which has 45,000 desktop users. Compatibility with existing applications appears to be the Transportation Department's major concern. According to a separate memo, a number of key software applications and utilities in use in various branches of the department aren't Vista compatible. Among them are Aspen 2.8.1, ISS 2.11, ProVu 3.1.1, and Capri 6.5, according to a memo issued by staffers at the DOT's Federal Motor Carrier Safety Administration. Any prolonged ban on new Microsoft technologies by the federal government could have a significant impact on the software maker's bottom line, as Microsoft sells millions of dollars in software to the feds annually. http://as.cmpnet.com/event.ng/Type=count&ClientType=2&AdID=125682&FlightID=75634&TargetID=2625&SiteID=222&AffiliateID=283&EntityDefResetFlag=0&Segments=1411,3108,3448,11291,12119&Targets=2625,2878,7904,8579&Values=34,46,51,63,77,87,91,102,140,222,227,283,442,646,656,1184,1255,1311,1405,1431,1716,1767,1785,1798,1925,1945,1970,2217,2299,2310,2326,2352,2678,2727,2767,2862,2942,3140,3347,3632,3636,3638,3890,3904,4080,448

# re: Office Open XML final draft!!! @ Wednesday, October 11, 2006 1:46 PM The past incarnations of DrawingML have been chaotic. It would be interesting, out of curiosity, to get an accurate history of what changed over time, perhaps to better understand what is supported in what. Here is my take, I am pretty sure I got at least 50% of it wrong :-) - pre-Windows 95 era, Word, Excel and Powerpoint use their own vector drawing layer used to draw shapes, pictures, diagrams, art and charts. Powerpoint, acquired by Microsoft in 1987, has by far the advanced drawing layer (bi-linear gradients, opacity, ...), codenamed Escher (in reference of the famous mathematician). - In Office 95, it is decided to reuse the Powerpoint vector graphics layer in Word and Excel. Migration begins. - Migration ends with Office 97 where both Word, Excel and Powerpoint use the same vector graphics layer, publicly known as MSO (mso97.dll) - In Office 2000, it's all craze about internet and Word tries to export WYSIWYG html. For that end, mark up extensions must be added to account for the MSO drawing layer. Hence the VML (Vector Markup language). Excel and Powerpoint don't support it. Internet Explorer natively supports VML (Internet Explorer's Direct animation vector drawing layer dismissed for performance reasons). - In Office XP, VML migration ends and both Word, Excel and Powerpoint support VML whenever a document is saved as a "Single web page archive" (.mhtml extension). - In Office 2003, nothing changes. - In Office 12, MSO gets rewritten with backwards compatibility in mind. The vector drawing layer uses more sophisticated drawing functionalities which makes it easier to draw themed, 3D realistic  objects. Technically, the differences are akin to the differences between GDI and GDI+. This new shared library is known as E2O and the corresponding mark up language is known as Drawing ML (Ecma TC45 specs). - In Office 14, ??? perhaps the drawing layer is rewritten, again, to 1) use WPF 2) to allow plugins, hence enabling much more sophisticated do-it-yourself scenarios. Use cases : custom charts ; BI analysis tools. Stephane Rodriguez

How come I am the one to notice how deficient ODF really is?

Much was made during the IS29500 standards process of the difference in the size of the ODF and Open XML specifications.  This is a good example of where that difference comes from: in this case, a concept glossed over in three vague sentences of the ODF spec gets 17 pages of documentation in the Open XML spec.

The precise proposed addition to the text of ISO/IEC 29500-4 is: §10.7, "Additional representation for dates and times (Part 1, Section 18.17.4 )" For a document of a transitional conformance class, each unique instant in SpreadsheetML time shall be stored as an ISO 8601-formatted string or as a serial value. This would override, for files of the "transitional" conformance type, the statements in Section 18.17.4 which allow only the ISO 8601 date format.

I have been shocked to find that they're actually proposing to re-introduce the leap-year bug
