Microsoft Ends Era Of Closed File Formats

RzUpAnmsCwrds writes "According to an MSDN Channel 9 interview with an Office file-format developer, the next version of Microsoft Office (Office 12) will default to newly-developed XML file formats in Word, Excel, and PowerPoint. The new formats will apparently include XML files along with other files (images, etc) inside of a Zip file. Microsoft will also be providing extensive documentation of the new format to the public through MSDN. The developer likewise announced that Microsoft would be releasing updates for Office 2000, XP, and 2003 to read and write the new formats when the new version of Office is released. If this interview is correct, it could mean the beginning of the end of Microsoft's proprietary file formats." Coverage at Beta News, Information Week, and the Washington Post.

Microsoft begins era of patent encumbered formats

[dyfet]

Take look at Office 2003 XML Reference Schema Patent License and reconcile that with the claims and headline of this article.

In particular; consider "Microsoft may have patents and/or patent applications that are necessary for you to license in order to make, sell, or distribute software programs that read or write files that comply with the Microsoft specifications for the Office Schemas." taken from the same page...

What changed? How is that an "improvement" exactly?

Lock-in continues via DRM

[SgtChaireBourne]

Would'nt this approach cause MS to loose its lock-in ability based on file format?

No. The lock-in continues via DRM and ties to "Office Servers". MS is really pushing the server based aspects of Office 12, so there will be hooks to the server like crazy. MS is also really pushing the DRM encumberance in Office 12. In all likelihood, the XML files will still have key components encrypted so as to support MS' DRM and as a 'side effect' lock out competitors.

The interesting thing is that all this server based control and logging of DMR'd functions gives an enormous boost to the type of information available for international and corporate espionage. Through backdoors, security holes or escrow keys it was possible before to get only the documents themselves for the most part. Now it's possible to monitor who's collaborating with who, and see everyone in the distribution chain.

That much can be guessed even now during the vaporware stages. However, as more technical information becomes available it will be possible to guess whether these same functions can be used for more than monitoring and can actually be used to stifle or suppress dissent or specific individuals or groups.

I use Open Office exclusively and have for the past couple of years. Reading the files in certainly isn't a problem for me. The only files that are slow to load are the master document files, and that's because they link to dozens of other files.

The XML specification is being expanded (it might already be done) to allow binary formats. There are good reasons, though, why it's best to keep data files in straight XML text format. It eliminates the need to worry about machine architecture. Little endian or big endian, it maks no difference to you. The files are perfectly portable across platforms, which is increasingly important these days. XML files zip very nicely, making them almost as small as a corresponding binary file.

It is far easier to provide backwards compatability to earlier file formats when you are using XML than if you are using binary file formats. With XML, if it sees a tag it doesn't understand, the parser ignores it. If a binary file format loader sees stuff it doesn't understand, it bails out with an illegal file format error.

When you move to a new expanded file format with XML, you don't have to write a conversion utility. Since you are merely adding new tags, your program can read any of your old data just fine, then add the appropriate tags and new data. This saves a great deal of trouble for programers.

Machines are fast and cheap. People are slow and expensive. It is far better to have our computers do a little extra work on loading a text file and eliminate conversion utilities and complicated loading routines that a prone to bugs.
