iAccessible2 and the importance of cross platform standards
Elizabeth Montalbano and Andy Updegrove write about IBM’s donation of iAccessible2 to the Free Standards Group, which is being formally announced today (see the IBM and FSG press releases). In addition to IBM, the project is backed by Sun, Oracle, SAP and other major vendors.
This is a big deal in and of itself, of course, because it will make applications based on ODF, AJAX, and other emerging open standards more accessible to visually impaired users. But it’s also an important milestone for the FSG, so I thought I should say a few words about that here from my own little pulpit.
The first clue is that iAccessible2 is an accessibility API for Windows. Windows? Yes, the FSG is primarily a Linux organization (our main project is, of course, the Linux Standard Base), so why on earth are we now involved in building APIs for Windows?
First of all, we’ll be moving this project forward as an extension to our existing accessibility projects—which, given the way the FSG is structured, flow into the LSB as they are adopted by the Linux distributions (who, as I’ve already mentioned here, are active participants in the LSB project, so we’re not just hoping the distros adopt our work, we’re proactively trying to drive consensus on these key issues). So, this definitely impacts our Linux work by bringing accessibility features to Linux that not only equal those of Windows but exceed them (iAccessible2 itself came about because Microsoft Active Accessibility has notable shortcomings).
But it’s more than that. Another way to look at this is that the LSB APIs will be taking on a distinctly more cross platform flavor, particularly in the “around the edges” cases such as this. Again, that begs the question: Why is cross platform support important for a Linux organization? That one’s simple. APIs are for application developers. Application developers target multiple platforms. The less Linux specific work an application developer has to do to support Linux, the more cost effective a Linux version will be, the more likely it is to get done. It’s all about more Linux apps.
There’s another dimension to it as well. There are a certain class of features that the vast majority of developers don’t think much about because that vast majority doesn’t need them. There’s no itch to scratch, as it were. Accessibility is a great example of such a feature: I have no idea what it’s like to be blind, nor do most people. If we can provide a set of open, cross platform APIs that allow application developers to easily add such features to their products, more standards based products will support them.
As Massachusetts and ODF brings into sharp focus, these “around the edges” cases developers don’t think much about can turn out to be very important indeed.
Abstract the abstraction layer(s)
InfoWorld: “Initially, Liquid VM will work only with VMware’s ESX Server hypervisor, but BEA plans to support other hypervisors in future including those from XenSource and Microsoft.”
VMware as operating system?
Now this is interesting: BEA is coming out with a version of its application server that runs directly atop VMware.
With this move, VMware takes another step toward becoming a full fledged operating system in its own right. VMware is already promoting the distribution of applications as virtual machine images, and operating systems are first and foremost application platforms. If VMware is an application platform, why not cut out the middle man entirely, particularly given that the middle man adds a few hundred megabytes of largely invisible baggage to the application, not to mention an enormous amount of maintenance burden for the ISVs that make or break an application platform?
For me, the real question is: Why BEA and not VMware? A JavaOS makes a lot of sense, since it builds on one of the world’s largest developer communities—it’s a well known environment among developers, and there are a huge stable of applications that could take advantage of the new platform with minimal porting. Furthermore, applications are increasingly server based, with the browser providing the UI, so this matches well with industry trends and nicely addresses the problem that VMware would have a very hard time building any sort of graphical user interface into its platform, just given the nature of what it is.
That said, VMware should really want to provide the JavaOS directly. With Xen and Virtual Server moving aggressively to bundle their products with widely deployed operating systems, the game’s already afoot, and if virtualization becomes just another operating system feature, VMware is at a distinct disadvantage, as it owns no operating system to bundle its product with. Finally, what about standards? New kind of operating system or operating system feature, there are going to be multiple application platforms if history is any indication (and it usually is), so how do applications take advantage of the new platforms without the inevitable fragmentation?
It’s going to be an interesting space to watch, that’s for sure.
Now *this* is Office 2.0
It’s now possible to dynamically link web data into Google spreadsheets. For example, stock information can be pulled in via the simple formula GoogleFinance(ticker, attribute), where attribute can be any number of metrics from market capitalization to P/E ratio. Not much to choose from yet—at this point, there’s only GoogleFinance and GoogleLookup, which seems more novelty than useful, and I’d love to see more than just the obvious metrics available for GoogleFinance, things like cash per share, revenue growth over the past m years, number of insider purchases over the past n months, etc. However, it’s a great start, and it’s pretty easy to see where they’re going with this—after all, most spreadsheets are inherently linked to external data sources, though I’d wager a majority of them are “linked” via copy and paste. I look forward to the day when you can pull in all manner of structured information into a spreadsheet via similar formulas.
To me, this is the real value of “Office 2.0”. To compete, the office challengers have to go beyond just copying Microsoft Office on the web—success will come from exploiting the new platform, not cloning the old model. Pretty easy to see something like this grow into a platform all its own too. With a few more financial metrics, a slightly more powerful macro language, and the ability to connect to more arbitrary data sources (say, Google Base or the CSV files my bank makes available to me), I could track my finances on the web in a Google spreadsheet and give Quicken the boot (for what I want to do, Quicken is like driving a nail with a sledgehammer).
Me: “[T]here are some pretty significant problems with the new [del.icio.us] extension, the biggest in my view being that there’s no way to change the sort order of the bookmarks within your favorite tags.”
An update came across the wire over the holiday weekend, and it is now possible to sort bookmarks alphabetically within your favorite tags.
Eric Schmidt: Making it simple for users to walk away from a Google service with which they are unhappy keeps the company honest and on its toes, and Google competitors should embrace this data portability principle.
Jeff Bezos: “We make muck so you don’t have to.”

del.icio.us, fully integrated with browser bookmarks
Yahoo quietly released the del.icio.us Bookmarks Firefox extension the other day, which does something I’ve been wanting del.icio.us to do for a very long time, namely fully integrate with Firefox bookmarks.
Like a lot of people, I gave up long ago on using bookmarks to keep track of interesting sites (del.icio.us fills that role quite nicely for me now). Still, the process of bookmarking something in del.icio.us had always been a bit tedious. The old del.icio.us extension helped a little (it would prefill the Notes field with whatever text was currently selected), but it was still missing some pretty important functionality (the popup didn’t display your existing bookmarks like the bookmarklet did). And even with del.icio.us, I still used browser bookmarks for quick access to the sites I frequent most via the bookmarks toolbar.
The new extension integrates with browser bookmarks almost perfectly—with a few big exceptions. It’s easy to import your existing bookmarks (the extension even offers to give them a special tag and mark them “private” so as not to clutter your existing bookmarks, as well as mines existing tags to try to categorize what’s imported automatically). The tag button is much more functional now and offers to show your existing tags, my big complaint about the previous extension. And the new extension nicely replaces the bookmarks toolbar and allows you to specify and even order your favorite tags, effectively replacing the last useful vestiges of browser bookmarks with a del.icio.us backed equivalent that also allows you to give other tags to those bookmarks.
That said, there are some pretty significant problems with the new extension, the biggest in my view being that there’s no way to change the sort order of the bookmarks within your favorite tags. Essentially, this makes the bookmarks toolbar far less useful—selecting “apps”, which used to contain a manually sorted list of web applications I frequently use, now contains a list of bookmarks in seemingly random order (it’s actually reverse chronological, but that’s not particularly useful for the bookmarks toolbar). The tags submenu under bookmarks doesn’t have any hierarchy to it—all tags are at the top level, making getting to a tag later in the alphabet quite tedious (I’d rather see a “tags starting with a”, “tags starting with b”, etc. structure). And, at least in my early experimentation, synchronization doesn’t always work as expected—changes to my local bookmarks seem to propagate back to del.icio.us, but the reverse doesn’t always seem to be true.
Still, it’s a promising start, and I’m going to keep using it. If they don’t fix the sort problem soon, though, I’ll likely revert to Google Browser Sync. (Interestingly, Google Browser Sync is listed as incompatible and is disabled on installation of the del.icio.us extension, even though it technically does other things, like synchronize cookies and passwords. This would seem to be a smart move on Yahoo’s part—challenge Google’s foothold in the browser and create a foothold of its own.)
A few parting thoughts: I’ve only installed this extension on my laptop thus far, and it’ll be interesting to see how well synchronization of my bookmarks works across machines (will it synchronize my favorite tags etc., allowing me to maintain a consistent browser toolbar? etc.). Finally, I’d like to see the “tag” function better integrated with the browser, perhaps the way Flock does it (a Google like star next to the address bar that reflects the current site’s del.icio.us state).
