Challenges: Some Ugly Truths
The challenges of building—and living with—an XML workflow are clear enough. The return on investment is a long-term proposition.
Regardless of the benefits XML may provide, the starting reality is that it represents a very different way of doing things than the one we are familiar with. The Word Processing and Desktop Publishing paradigm, based on the promise of onscreen, WYSIWYG layout, is so dominant as to be practically inescapable. It has proven really hard to get from here to there, no matter how attractive XML might be on paper.
A considerable amount of organizational effort and labour must be expended up front in order to realize the benefits. This is why XML is often referred to as an “investment”: you sink a bunch of time and money up front, and realize the benefits—greater flexibility, multiple output options, searching and indexing, and general futureproofing—later, over the long haul. It is not a short-term return proposition.
And, of course, the returns you are able to realize from your XML investment are commensurate with what you put in up front: fine-grained, semantically rich tagging is going to give you more potential for searchability and recombination than a looser, more general-purpose approach, but it sure costs more. For instance, the Text Encoding Initiative (TEI) is the grand example of pouring enormous amounts of energy into the up-front tagging, with a very open-ended set of possibilities down the line. TEI helpfully defines a level to which most of us do not have to aspire.[5]
But understanding this on a theoretical level is only part of the challenge. There are many practical issues that must be addressed. Software and labour are two of the most critical. How do you get the content into XML in the first place? Unfortunately, despite two decades of people doing SGML and XML, this remains an ugly question.
Gary Edwards on 27 Jun 14"On mobile devices, the Web hasn't lived up to its promise of a universal programming foundation. Google is trying to change that." Android hogged the spotlight at Google I/O, but performance improvements in Google's Chrome browser show that the company hasn't given up on trying to advance its other programming foundation -- the Web. The mobile version of Chrome has become much more responsive since 2013, said Paul Irish, a developer advocate on the Chrome team, speaking at the San Francisco conference. "We've improved the speed of animation by 75 percent and of scrolling 35 percent," Irish told developers Thursday. "We're committed to getting you 60 frames per second on the mobile Web." That performance is crucial for persuading people to use Web sites rather than native apps for things like posting on social networks, reading news, and playing games. It's also key to getting programmers to take the Web path when so many today focus on native apps written directly for Google's Android operating system and Apple's iOS competitor. The 60 frames-per-second rate refers to how fast the screen redraws when elements are in motion, either during games or when people are doing things like swiping among pages and dragging icons. The 60fps threshold is the minimum that game developers strive for, and to achieve it with no distracting stutters, a device must calculate how to update its entire screen every 16.7 milliseconds. Google, whose Android operating system initially lagged Apple's rival iOS significantly in this domain of responsiveness, has made great strides in improving its OS and its apps. But the mobile Web hasn't kept pace, and that means programmers have been more likely to aim for native apps rather than Web-based apps that can run on any device. ............................ Good review focused on the growing threat that native "paltform specific" apps are replacing Web apps as the developer's best choice. Florian thinks that native apps will win
