If you want to help Mozilla to make Firefox better but you are not a developer, here is your chance. Earlier this year, Mozilla announced the launch of Test Pilot , the organization's new distributed usability lab. Test pilots will be enlisted in various usability tests and will be some of the first to see some of Mozilla's ideas for new user interfaces and Mozilla Labs products. We first wrote about Test Pilot when it was just a "still-in concept platform." Now, however, you can download the Test Pilot add-on for Firefox 3.5 here and begin to help Mozilla make Firefox even better. Sponsor Editor's note: This story is part of a series we call Redux, where we'll re-publish some of our best posts of 2009. As we look back at the year - and ahead to what next year holds - we think these are the stories that deserve a second glance. It's not just a best-of list, it's also a collection of posts that examine the fundamental issues that continue to shape the Web. We hope you enjoy reading them again and we look forward to bringing you more Web products and trends analysis in 2010. Happy holidays from Team ReadWriteWeb! First Tests Are Coming Soon For now, Mozilla will start the program with a survey that aims to get a better understanding of who is joining the Test Pilot community. The first actual tests should arrive soon after this first survey is complete. Mozilla stresses that it will take its users' privacy seriously. Participants have to opt-in and data will be stored in anonymous form. Only aggregate test data will be made available to the public. Overall, this looks like a great project. Usability studies tend to be slow and costly, yet with Test Pilot, Mozilla will be able to quickly enlist feedback about new design ideas from its large community of users. Discuss

Become a Test Pilot: Mozilla Wants Your Help To Make Firefox Better

This week ReadWriteWeb will run a series of posts detailing what we think are the five biggest, most cutting-edge Web trends to come out of 2009. We'll be posting one trend analysis per day. Then at the end of the week we'll publish a major update to our standard presentation about web technology trends. The first major Web trend we're looking at is Structured Data . In prior presentations , this has sometimes been referred to under the umbrella term of 'Semantic Web'. However the way 2009 has panned out so far, it's become clear that this trend is much more than the Semantic Web. In this post, we'll analyze the developments in Structured Data this year and provide you with 3 product examples: OpenCalais, Google, Wolfram Alpha.

Web of Data, Not Documents Tim Berners-Lee said in February this year that we're now in a Web of Data , rather than a Web of Documents. The organization that Berners-Lee heads, the W3C, has heavily promoted two key initiatives that are helping to build this Web of Data: the Semantic Web and more recently Linked Data . However over the past few years, we've seen that there are many other ways to structure data and enable others to build off it. The best current example is surely Twitter , whose API has historically been responsible for around 90% of Twitter's activity - via third party apps. The basic principle of the Web of Data is still the same as what Alex Iskold articulated on ReadWriteWeb back in March 2007: "unstructured information will give way to structured information - paving the road to more intelligent computing." Example 1: OpenCalais Our first example product, OpenCalais , is probably the best current example of Linked Data (which is a type of structured data endorsed by W3C). Thomson Reuters, the international business and financial news giant, launched an API called OpenCalais in Feb '08 . In a nutshell, OpenCalais turns unstructured HTML into semantically marked up data. It orders data into groups such as 'people,' 'places,' 'companies' and more. This way, third party applications and sites can build interesting new things from that data - one of the defining principles of Linked Data. For a full explanation of Linked Data, read Alexander Korth's technical introduction The Web of Data: Creating Machine-Accessible Information from April 2009. I also explained the background and benefits of Linked Data in a May '09 post entitled Linked Data is Blooming: Why You Should Care . Example 2: Google Rich Snippets In May this year, Google added structured data to its core search, in the form of a feature called 'Rich snippets.' Essentially this feature extracts and shows useful information from web pages, by way of structured data open standards such as microformats and RDFa. On launch in May, Google invited publishers to mark up their HTML. While it will take a while for this markup to become widespread, the fact that a huge company like Google implemented it shows the increasing importance of structured data on the Web. Other big companies are also heading in this direction - in particular, Yahoo was an early leader . Example 3: Wolfram Alpha Ever since Wolfram|Alpha 's much hyped launch in May , we've been tracking this innovative product closely. It's a self-described "computational knowledge engine" and while it's not quite the Google killer some predicted, it has many potential uses . Wolfram|Alpha has a search engine-like interface, allowing you to type natural language statements into it. But the main part of the product is the computations you can do on data. The product is premised on using and computing data . If Web 2.0 was about creating data (a.k.a. user generated content), then the next generation of the Web is all about using that data. Conclusion We can see from the above three examples that structured data is rapidly becoming a feature of today's Web. Companies like Thomson Reuters and Google are enabling data to be structured, and new types of products (like Wolfram|Alpha) will make use of structured data in ways we perhaps can't imagine right now.

Top 5 Web Trends of 2009: Structured Data

Ever since Jeff Han demoed his Multi-Touch Workstation at the 2006 TED Conference , the world has been waiting for a high resolution sensory work experience. As a generation of hunched night creatures with intimate knowledge of our chiropractors, we've suffered and conformed to our traditional interfaces for too long. Touch was the future of workstations. But as articulated by ReadWriteWeb , the upcoming Apple tablet is not the workstation of the near future. It simply isn't practical. For those of us who still want to gawk at the cool regardless of its practicality, here is an assortment of 2009's most interesting interfaces. Sponsor Editor's note: This story is part of a series we call Redux, where we'll re-publish some of our best posts of 2009. As we look back at the year - and ahead to what next year holds - we think these are the stories that deserve a second glance. It's not just a best-of list, it's also a collection of posts that examine the fundamental issues that continue to shape the Web. We hope you enjoy reading them again and we look forward to bringing you more Web products and trends analysis in 2010. Happy holidays from Team ReadWriteWeb! Sixth Sense : Sixth Sense is an extremely inexpensive interface ($350 to build the prototype) and it consists of some colored finger markers, a projector, and a camera on a necklace. Demoed at the TED conference, this interface has amazing potential. We reviewed this product as part of our post The Wearable Internet Will Blow Mobile Phones Away . Given Nikon's release of yesterday's first camera with a built-in pico projector and Mobileburn's demo of the Samsung Anycall Show phone , these little projectors are about to start popping up everywhere. For Minority Report fans, we may actually see these projector based interfaces used up for everyday tasks; however, it's more produce amazing entertainment for gamers. Perceptive Pixel Multi-Touch Wall (Jeff Han's new project) and Microsoft Surface : In the world of alternative interfaces, these two workstations are extremely well known. Certainly not the inexpensive, mainstream touch interfaces we'd hoped for, their size and price makes them unobtainable to the average user. However, for commercial uses, they've certainly got that wow factor. The products are used for story boarding, geo-spatial command, broadcast media, museum exhibits, hotels and Surface is even in Disneyland's tomorrow land. Scratch Input: Recently featured in Technology Review for his presentation at the SIGGRAPH Conference , Carnegie Mellon Ph.D student Chris Harrison created a gestural input interface using existing surfaces and an acoustic input technique. In other words, Harrison's interface uses scratches to communicate with his machine. By taping a modified stethoscope to a wall, Harrison got users to perform six scratch input gestures at about 90% accuracy with less than 5 minutes of training. If Scratch Input were utilized by a mobile manufacturer, a phone owner could simply rest their device on a table top and use it to scribble out messages. Pulp-Based Computing : While there's little information on these projects just yet, one thing is clear. The folks in MIT's Media Lab Fluid Interfaces Group are exploring electrically active inks and fibers during the paper making process to create a new form of paper-based computing. Apparently the paper would react in the same way as regular paper; however, it would also carry digital information. While the project is only in its early stages and appears to be hooked up to a basic Arduino prototyping platform , theoretically this could be used to create a new type of Wacom tablet. Remember when Steven Levy wrote about losing his Macbook Air ? A paper interface would take some serious getting used to. Siftables : Created by David Merrill and Jeevan Kalanithi, Siftables is a series of blocks that contain built-in motion sensors, graphical displays and wireless communication. The blocks can be programmed to interact with digital information and media to form a collective interface. Siftables have been used to create art displays, painting tools, calculators, games and even a music sequencer . Bug Labs also offers a similar open source block system for modular device interfaces.

Where's my Jet Pack? Apple Tablet and Future Interfaces

During my trip to Boston earlier this year, I had the opportunity to visit MIT. At the end of a long day of meetings with various MIT tech masterminds, I made my way to the funny shaped building (see photo right-below) where the World Wide Web Consortium (W3C) and its director Tim Berners-Lee work. Berners-Lee is of course the man who invented the World Wide Web 20 years ago. This was my first meeting with the Web's creator, whose work and philosophy was a direct inspiration for me when I launched ReadWriteWeb back in 2003. 1 Sponsor Editor's note: This story is part of a series we call Redux, where we'll re-publish some of our best posts of 2009. As we look back at the year - and ahead to what next year holds - we think these are the stories that deserve a second glance. It's not just a best-of list, it's also a collection of posts that examine the fundamental issues that continue to shape the Web. We hope you enjoy reading them again and we look forward to bringing you more Web products and trends analysis in 2010. Happy holidays from Team ReadWriteWeb! After shaking hands, I told Tim Berners-Lee that this blog's name was in part inspired by the first browser, which he developed, called " WorldWideWeb ". That was a read/write browser; meaning you could not only browse and read content, but create and edit content too. It was a shame then when Mosaic, a read-only browser, became the first mainstream Web browser in the mid-90s. It wasn't until the rise of Web 2.0 that the read/write philosophy gained widespread acceptance. 2 On that note, we launched into the interview... Note: the interview was published in two parts, with Part 1 on the topic of Linked Data. Part 2 explored other topics and can be found here . How Linked Data Relates to The Semantic Web RWW: Earlier this year you gave an inspiring talk at TED about Linked Data . You described Linked Data as a sea change akin to the invention of the WWW itself - i.e. we've gone from a Web of documents to a web of data. Can you please explain though how Linked Data relates to the Semantic Web, is it a subset of it? TBL: They fit in completely, in that the linked data actually uses a small slice of all the various technologies that people have put together and standardized for the Semantic Web. Linked Data uses a small slice of the technologies that make up the Semantic Web. We started off with the Semantic Web roadmap, which had lots of languages that we wanted to create. [However] the community as a whole got a bit distracted from the idea that actually the most important piece is the interoperability of the data. The fact that things are identified with URIs is the key thing. The Semantic Web and Linked Data connect because when we've got this web of linked data, there are already lots of technologies which exist to do fancy things with it. But it's time now to concentrate on getting the web of linked data out there. Web inventor Tim Berners-Lee and ReadWriteWeb founder Richard MacManus How Linked Data Has Evolved via Grassroots RWW: Linked Data has had a lot of grassroots support, which you mentioned in your TED speech. This is something Semantic Web technologies, such as RDF, have struggled to get over the years. Has the W3C been pushing the more bottom-up Linked Data world, because of the frustration over lack of take-up of top-down Semantic Web ? TBL: A lot of the initial RDF and OWL projects came out of the academic world; and some of them were projects to show what you could do in a closed world. And the files were zipped up and left on a disc. While they were interesting projects, and while the systems were useful systems, the Semantic Web community maybe missed the point of the 'web' bit and focused too much on the 'semantic'. However the work that's been done in the Semantic Web, the standards, was really valuable. It's relatively recently for example that SPARQL [an RDF query language] has been developed. "It's time now to concentrate on getting the web of linked data out there." Somebody drew an analogy the other day: can you imagine trying to promote a world of databases without SQL? Even though it's not an interoperable protocol, it's just a query language. So similarly, all that's been put into RDF, rdfs and OWL is very valuable to the linked data community. The Linked Data community tend to use a subset of that [Semantic Web technologies], of OWL for example. But they certainly use SPARQL. So you could argue that really it wasn't ready to be deployed widely. Linked Data started as a very informal Design Issues note that I put in; it was a grassroots movement from very early on. So yes W3C has been emphasizing the importance of Linked Data. It's been the Semantic Web Interest Group of course, and various [other Semantic Web] activities, which has been pushing it. But also Linked Data has been seized on - a group of people for example put together DBpedia . 3 That wasn't commissioned, that was that they just thought it would be a really cool idea. Graph of Linked Data sets on the Web, as at March 2009 Linked Data and Governments RWW: In a recent Design Issues note , you urge governments to put their data online as Linked Data (although you'd also be happy for governments to just make available the raw data - presumably so that others can then structure it). What do you realistically expect, for example, the U.S. or U.K. governments to do over the next year? And in the near future, do you foresee different governments interconnecting their Linked Data sets? TBL: One can't generalize, governments are (like most big organizations) fascinatingly diverse inside them. So you'll find that there are places inside governments where you get a champion who gets linked data and who's just written a script and produced some linked data. So in the UK government for example, you'll find there's RDFa [in the code of its website] for civil service jobs. So if somebody wants to make a database of all the jobs, they can do that very easily. "The first step of actually putting the data out there is the one that nobody else can do." There are other cases where the easiest thing for somebody to do is to just put data up in whatever form it's available. Comma separated values (CSV) files are remarkably popular. They're exported sometimes from spreadsheets. It's remarkable how much information is in spreadsheets. Or sometimes pulled out of a database and then put up on the web. It's not as good, not as useful to the community, as if Linked Data had been put up there and linked. But the first step of actually putting the data out there is the one that nobody else can do. Data.gov , a catalog of public data, was launched in May by the U.S. government The way to go is for government departments to go the extra step and convert [their data] into Linked Data. One of the nice things about Linked Data, when they have a pile of it, is that they could run a SPARQL server on it. SPARQL servers are a commodity product, a solution for all of the people who say 'but actually I wanted to have XML.' A SPARQL server will generate an XML file [and] allow somebody to write out, effectively, a URL for the XML file. "Linked Data is the backplane, it's the thing that you connect to in both directions." In fact, I don't see why SPARQL servers shouldn't provide CSV files, something which as far as I know isn't in the standards. But I'd recommend it, certainly in government context, because CSV files are what people have and what people want. So the message [for government] is to use RDF. Linked Data is the backplane , it's the thing that you connect to in both directions. As a [web] producer your job is to make sure that you produce Linked Data one way or another. And as a consumer, there are lots of ways to consume that data once it's out there as Linked Data. In Part 2 of this interview we discussed: how previously reticent search engines like Google and Yahoo have begun to participate in the Semantic Web in 2009, user interfaces for browsing and using data, what Tim Berners-Lee thinks of new computational engine Wolfram Alpha, how e-commerce vendors are moving into the Linked Data world, and finally how the Internet of Things intersects with the Semantic Web. Read Part 2 here . Footnotes: 1. The very first sentence written on this blog , on 20 April, 2003, was: "The World Wide Web in 2003 is beginning to fulfill the hopes that Tim Berners-Lee had for it over 10 years ago when he created it." 2.
