Structured Blogging Initiative

http://redherring.com/Article.aspx?a=14902&hed=Semantic+Web%2c+Here+We+Come

The "Structured Blogging Initiative" is an attempt to jump-start the "semantic web," the idea of giving deeper meaning to the Internet advocated by World Wide Web creator Tim Berners-Lee. By incorporating descriptive information into the code of web pages, laypeople will be able to designate their content as a movie review, an event posting, or an item available for sale.

The idea is to spark massive amounts of web pages using these formats so that companies and applications can be formed to make use of the information; for instance, an alternative to eBay that collects listings from blogs rather than requiring sellers to sell within the confines of its marketplace.

"If you've got something to sell, you put that on your own blog," said Bob Wyman, CTO of PubSub, which has spearheaded the initiative. "What we're looking for is a world in which you own your own data."
...
PubSub's main project is a kind of search engine that focuses on the newest information on the Internet, letting users subscribe to keywords they're interested in so they can stay on top of the information.

PubSub hired Marc Canter of Broadband Mechanics, who founded MacroMind, to develop plug-ins for the widely used blogging platforms WordPress, Movable Type, and Drupal.


It seems this is another variation in the age-old question of pre-determined vs freely assigned indexing:
Figuring Out Categories

Though Mr. Wyman blasted the “walled garden” approach of today’s web—where local restaurant reviews, for instance, are replicated on multiple sites but can’t be viewed together—he said he supported Google’s new database project, Google Base.

Google Base has been criticized for trying to collect information in a closed system. However, the free database could provide a way for users and companies to get by without paying for or building a database of their own, said Mr. Wyman.

But how will Google’s categories be reconciled with Structured Blogging’s, or anyone else’s for that matter? What if one user’s movie reviews are on a scale of four stars, and another user’s on a scale of 10?

Mr. Wyman insists that some core categories and templates will emerge. He is working with Google to make sure the “schemas” are aligned.

But while top-down categories undoubtedly make things easier to combine, they are at odds with the emerging bottom-up categorization systems like tagging (user-generated labels created in free association with an object like a web page or a photo).

The interplay between categorization systems is likely to be increasingly important as online content proliferates.

Webcams part 2 - for family chats on the net

The most common scenario for using a webcam is with IM. What do Yahoo and Hotmail say about supported webcams?

Yahoo links from their Messenger Webcam page to a promo for Creative webcams ranging from $30 - $150. The features that distinguish them are:
* microphone at $50
* USB 2.0 at $80
* Smart face tracking at $80
* 30 frames/sec at $80
* whether its mounts on a notebook
* auto-pan and tilt
* CCD better than CMOS imaging element

The Super Webcam page at Yahoo says that with basic Webcam, frames refresh only about once a second, and the maximum resolution is 160 x 120. With Super Webcam, frames refresh up to 20 frames a second, and the maximum resolution is 320 x 240.

The Yahoo Messenger "Learn More" page promotes PC-to-PC calling. With a link to a Plantronics .Audio 70 headset - 1 for 26.95, 2 for 41.93.

MySimon has this webcam price/feature listing . Logitech and Creative dominate. They describe the cameras based on megapixels ( 1.3 is common.)

The ConsumerSearch site has this review.

This is a really cool site because it reviews the reviews. They really like the reviews at Consumer Guide, including this listing of webcam reviews..

Consumer Guide is a gold mine. Although we wish models were compared to each other, there are at least savvy write-ups here for current Webcams. The Veo Velocity Connect USB 2.0 and ADS USB Turbo 2.0 are the best Webcams if you have a USB 2.0 port and a broadband connection. The latter includes a nice software bundle. The Creative Labs WebCam Pro EX has a better CCD sensor and good color, as well as an included [headset] microphone; however it's USB 1.1. The review also gives good ratings to the Logitech QuickCam Pro 4000, which comes with a microphone, generous software and both Mac and PC compatibility. The Logitech QuickCam Orbit, which tracks your face when you move, is another well rated Webcam, but the review says it's expensive. The Logitech WebCam is the best cheap model, but isn't great in low light.

"Reviews say the [Logitech] QuickCam Pro 4000 is the best mainstream Webcam. The QuickCam has a 640 x 480-pixel CCD sensor, a digital zoom, an integrated microphone and can shoot 1.3-megapixel still photos. Owners on user-review sites rave about the Logitech Webcam's picture and sound quality. Low light is a big problem for most Webcams, but the Logitech has better light-gathering capability than others. The only major feature it's missing is face-tracking software." But to me, that's one less thing to muck with. The Consumer Guide review says that the interface is the older USB 1.1 standard, which means that the camera will be just barely able to transfer full-motion 30fps video to the PC. It seems that 30fps across the internet just doesn't happen yet, although netmeeting may do it.

An ad here tells me that Walmart sells the Creative Webcam Live! Pro. Image Sensor Type: CMOS, Interface: USB 2.0, 30 frames per second, Video Capture Resolution 640 x 480

" Amazon is becoming an increasingly reliable source for owner-written reviews and ratings. Interestingly, no camera gets unequivocal raves; all seem to have image issues, driver problems or incompatibilities. The Creative WebCam NX Ultra gets better ratings than others; the Creative WebCam NX and WebCam Live do fairly well. The Logitech QuickCam Chat and QuickCam Orbit get more complaints than others."

We could also consider what software comes with a webcam that would be fun to use if we all had the same kind?

More expensive: Logitech QuickCam Pro 4000
Creative WebCam Live Ultra
ADS Technologies Turbo (USB 2.0)
Veo Velocity (USB 2.0)

Less expensive: creative labs webcam live
Logitech QuickCam Chat Webcam with USB 2.0 Output, Microphone & Headset and Software - Win
Logitech Quickcam Communicate Web Cam

Logitech QuickCam Chat $20 at Amazon http://www.amazon.com/gp/product/B00077IGZ2/sr=1-1/qid=1134353523
- one user preferred creative webcam live

Creative WebCam Live - Amazon comments - this camera had a delay of almost a 1/2 second between the audio and the video... In my opinion it would be better just to have audio than to have every single syllable out of synch with the video, which I find to be very distracting.

ADS Technologies Turbo < $50 delivered at http://www.bhphotovideo.com/bnh/controller/home?A=details&amp;Q=&is=REG&O=productlist&kw=ADWCU&cpncode=10-14271597-2&sku=263758&srccode=cii_5784816
That's a good looking supply site for video - B&H Photo

Amazon review comments:

- Can only capture 160x120, 320x240, or 640x480 sizes. You really need 352x288 for videoconferencing.
- The price is good, but the image quality is poor. The images are very dark under indoor light, and if the low-light option is clicked in the driver, then the images are bright but the camera suffers from extreme motion blur that makes it unusable.
+ As far as brightness goes, the video off this webcam is not very bright. But this sacrifice is acceptable since gamma correction usually reduces image quality so just turn on the lights when you use it. Its that simple.
+ the button on the camera neatly triggers a capture routine that pops-up a window with a still ready to be saved to file

The bottom line
It seems maybe that USB 2.0 cameras suck up more CPU (1GHz minimum) and don't do as well in low light conditions. Hmm. Maybe the older ones are better. But even they are subject to flakiness on upload speeds and configuration.

I'm changing my approach to "family sharing" on the internet, to miminize shared headaches: a good headset like the Plantronics, a copy of Netmeeting or Yahoo IM with Voice to share screens, photos and conversation, and a tripod to hook up the digital cameras we already own. You can drag/drop still pictures into the chat. Also, it might be that our current cameras are useable as webcams. NetMeeting seems to be a free download / builtin to Windows..

Shared video can wait til bandwidth and processor power are one more generation along.

Webcams and other gadgets

The main medium for using webcams is video IM or video for VoIP. You might also want to use your webcam to record and publish a short video.

CNet 2005-08-15 -
"Logitech's new QuickCam Fusion is designed for that casual conversation between friends or as a Web conference business tool, the company said. Priced at $99.99 in the U.S and available this month in both the U.S. and Europe, the webcam features a wider lens with 78 degrees of visibility and requires Windows 2000 or XP to operate.... Video Effects software maps facial expressions by tracking up to 22 points on the face, around the eyes, eyebrows, and mouth... The software then allows you to pick your own avatar... which then mimics the facial movements and expressions determined by those points. Microsoft said it worked with Logitech to endorse both the webcam and the video effects software for Windows 2000 and XP. The webcam and software are also supported by AOL and Yahoo Instant messenger." That's from the Gadgets Blog at CNet.

Broadband Reports 2005-12-01 -
"Skype has launched the beta version of Skype 2.0, which integrates video-chat functionality. The program searches for a webcam and if present, provides a 4x4 inch video image for chatting (full screen if you've got the hardware). Though the official release will be a while, the Skype Web Store will be selling Logitech "Skype certified" webcams for the software, reports Techworld."

"S
kype will be multiplatform and multi-user and multi firewall (others still can't beat it there)"

"Everybody has these great 6mb download services but they forget that they usually only have 386k up."

Gizmodo 2005-12-01
"The Creative WebCam Instant Skype edition is certified by Skype for use with its video and comes with a personal headset with microphone, software and a standalone mic for conference calling. Also, Skype's Version 2.0 was announced (by eBay), adding the video calling feature as well as a toolbar for Microsoft's Outlook to make things easier. The cost for the camera is $47 and it also includes CMOS sensor that captures video at 352x288 pixels at 30 frames per second."

Chandler: open-source calendar

OSA Foundation President Mitchell Kapor says Chandler, a free calendar software, could follow in the footsteps of Firefox. Kapor tells CNET News.com's Charles Cooper at the When 2.0 conference that the software could be helpful for small work groups, families and informal groups. As of December 2005 it's at version 0.6, so "try it if you're willing to help us fix bugs." [http://news.com.com/1606-2_3-5985814.html]

Google blogs for product communication

OpenOffice 2.0 is out, and generating good news: Google throws bodies at OpenOffice and OpenDocument format gathers steam (IBM, others host conference to build on Mass.' statement of direction.)
Tim Coyle over at eHomeUpgrade has some excellent points about why Firefox extensions are a better place than Google to integrate all your Web resources. (Why Firefox is Web 2.0, Google Doesn't Get It and Microsoft Is Back in the Game) But even if that's true for now, I'd still like to keep the configuration data for my Firefox stack on the web, so that when I move from machine to machine I get the same consistent experience.

FlexWiki: Microsoft's latest Open Source project has some very cool features including... "Federation and namespaces - When there are many somewhat related Wiki sites, it's often hard to get them to link together smoothly. FlexWiki has some very cool features to support this scenario. Specifically, a single installation of FlexWiki (called a WikiFederation) can bind together multiple WikiBases. All topics in a WikiBase live in a TopicNamespace. See WikiFederationOverview. "

Home PCs not as protected as owners think: "While 77% of the survey respondents believed they were safe from online threats, two-thirds lacked current anti-virus software and did not use any firewall protection. More than half said they did not understand the difference between the two.
Yet 84% stored personal data on their home PCs, and 72% routinely used the Internet for sensitive transactions, such as banking and medical data exchanges.
When technicians examined their PCs, they found 80% loaded with dozens of spyware programs that track the user's Web-browsing habits. Cybercrooks also have begun spreading a more invasive kind of spyware, called keystroke loggers, that steal logins and passwords as the user types them in. " [USATODAY.com]

Tabbed Browsers Can Disclose Confidential Info: "Among the affected browsers are Mozilla 1.7.2 and 1.7.3, Firefox 0.10.1, Opera 6.x and Opera 7.x, Safari 1.x, Netscape 7.x, and Konqueror 3.x.
Some of the flawed browsers have already been repaired or will be fixed shortly. Konqueror, for instance, closed the vulnerability in the version shipped with KDE 3.3.1, while the newest versions of the Mozilla/Firefox browsers have been patched against the second of the vulnerabilities. Opera said it will correct the issue in the upcoming version 7.60 (the current version of Opera is 7.54).
According to Secunia, users should either disable JavaScript within their browsers, or not visit trusted Web sites--such as financial institutions or retail sites--when tabs showing untrusted sites are also open. "

InformationWeek > Sun Microsystems > Sun's Extreme Makeover > October 18, 2004: "Sun has been standing its business model on its head--transforming its most-important commercial software into open source, embracing standard chipsets, converting rivals into partners, and tailoring subscription-style services.. Next month, Sun is bringing out Solaris 10, an upgrade to its flagship Unix operating system that's more finely tuned for x86 microprocessors. This week, it's unveiling more pay-by-the-drink pricing options for grid computing. By year's end, it plans to finalize a sweeping plan to make its software available as open source, including a version of Solaris. And around the first of the year, it promises interoperability with Microsoft's identity-management and directory-services products.

Sun is betting it can make money from service and support agreements, not unlike Red Hat Inc.'s approach to Linux. "'f you want it fully supported or want input into new features, then you might have to pay for that,' Loiacono says.

It's part of a broader push into a software-as-services model. Sun provides hosted storage on an as-needed basis, and, in January, it established a $100-per-seat model for its Java Enterprise development platform, which has attracted more than 345,000 customers. Sun also introduced in September hosted grid computing for $1 per processor per hour and this week will disclose details of a plan for third-party hosting.

November's Solaris 10 launch comes after much work to optimize the operating system to run on x86 microprocessors from Intel and Advanced Micro Devices Inc. Sun finally hopes to smash the perception that Solaris' quality and performance come at a steep premium. Solaris is 'cheaper than Windows and less expensive than any of the major Linux distributions,' Loiacono contends.

In addition, Sun is almost ready to play its Microsoft card. Having reached earlier this year a $2 billion legal settlement that included cross-licensing of technology and a joint-development agreement, Sun and Microsoft have identified up to 20 areas of potential collaboration. Within the next 90 days, they'll deliver the first fruits of that work.

The companies will provide single-sign-on capability for Microsoft's Active Directory and the Java Enterprise LDAP Directory. Sun's CTO, Greg Papadopoulos, and Microsoft's chairman and chief software architect, Bill Gates, have been working closely the past few months on a road map to bridge the Sun and Microsoft environments. The companies say they'll unveil integration products a few times a year over the next 10 years, concentrating initially on interoperability among their messaging services, applications, and systems management. 'I don't anticipate that Microsoft is going to do any kind of similar deal with any of our major competitors,' Loiacono says. 'We have the inroad into technology and interoperability with them. Red Hat's not going to have this capability.'"

Software disasters are often people problems

Big software projects -- whether to manage supply chains, handle payroll, track inventory, prepare finances -- tend to begin with high expectations and the best intentions. They're all about efficiency, reliability, cost-savings, competitiveness.

Companies might develop their own programs internally, outsource the job or buy from a company such as SAP AG, Oracle Corp. or PeopleSoft Inc. Regardless of the route, it's usually a major undertaking to get things right. Often, however, the first step toward total disaster is taken before the first line of code is drawn up. Organizations must map out exactly how they do business, refining procedures along the way. All this must be clearly explained to a project's technical team.

"The risk associated with these projects is not around software but is around the actual business process redesign that takes place," said Bill Wohl, an SAP spokesman. "These projects require very strong executive leadership, very talented consulting resources and a very focused effort if the project is to be successful and not disruptive."

A 2002 study commissioned by the National Institute of Standards and Technology found software bugs cost the U.S. economy about $59.5 billion (euro48.35 billion) annually. The same study found that more than a third of that cost -- about $22.2 billion (euro18.04 billion) -- could be eliminated by improving testing.

Style Guide for Online Hypertext: This w3c piece by Tim Berners-Lee goes back to 1992, but has been maintained over the years. It is still a seminal introduction to things a new webmaster needs to remember. When you need an introduction to specific web site technologies, the w3c Tutorials are a good place to look.
What is a URI? It looks like the usage of this term has evolved. Around 1999, an article on URx said that "Uniform Resource Indicators (URI) are in development. URIs are defined as ASCII-based character string network protocols that represent communications streams... Identifiers are proxies for resources. A human being (resource) is labeled by a name (identifier), books are known by ISBN codes."

However the HTML 4.0 Recommendation and Terena's Guide to Network Resource Tools describe URI's as simply the protocol + host + path-within-host. Which leaves me wondering Is a URL any different from a URI? "URLs form a subset of the more general URI naming scheme."

The definitive clarification would be the w3C report URIs, URLs, and URNs: Clarifications and Recommendations 1.0 which "addresses how URI space is partitioned and the relationship between URIs, URLs, and URNs.... URL is a useful but informal concept: a URL is a type of URI that identifies a resource via a representation of its primary access mechanism (e.g., its network "location"), rather than by some other [identifying] attributes it may have. " By adding that "an http URI is a URL, " this puts our minds at rest -- we do not need to look for a distinction in http-space. "urn:isbn:n-nn-nnnnnn-n" is also a URI, but one based on an identifier (ISBN) rather than a location, and hence is not commonly referred to as a URL.

So we may as well just use the term URI universally, but there's nothing wrong with using URL in the context of location-oriented mechanisms like http. Some useful historical context is outlined at the http://www.w3.org/Addressing/.
