INTRODUCTION
Just in case you missed it, the web now has version numbers. Nearly three years ago, amid continued hand-wringing over the dot-com crash, a man named Dale Dougherty dreamed up something called Web 2.0, and the idea soon took on a life of its own. In the beginning, it was little more than a rallying cry, a belief that the Internet would rise again. But as Dougherty's O'Reilly Media put together the first Web 2.0 Conference in late 2005, the term seemed to trumpet a particular kind of online revolution, a World Wide Web of the people.
Web 2.0 came to describe almost any site, service, or technology that promoted sharing and collaboration right down to the Net's grass roots. That includes blogs and wikis, tags and RSS feeds, del.icio.us and Flickr, MySpace and YouTube. Because the concept blankets so many disparate ideas, some have questioned how meaningful—and how useful—it really is, but there's little doubt it owns a spot in our collective consciousness. Whether or not it makes sense, we now break the history of the Web into two distinct stages: Today we have Web 2.0, and before that there was Web 1.0.
Which raises the question: What will Web 3.0 look like? Yes, it's too early to say for sure. In many ways, even Web 2.0 is a work in progress. But it goes without saying that new Net technologies are always under development—inside universities, think tanks, and big corporations, as much as Silicon Valley start-ups—and blogs are already abuzz with talk of the Web's next generation.
To many, Web 3.0 is something called the Semantic Web, a term coined by Tim Berners-Lee, the man who invented the (first) World Wide Web. In essence, the Semantic Web is a place where machines can read Web pages much as we humans read them, a place where search engines and software agents can better troll the Net and find what we're looking for. "It's a set of standards that turns the Web into one big database," says Nova Spivack, CEO of Radar Networks, one of the leading voices of this new-age Internet.
HISTORY
The term Web 3.0 first appeared prominently in early 2006 in a blog article by Jeffrey Zeldman critical of Web 2.0 and associated technologies such as Ajax.
Just in case you aren’t aware, Web 2.0 is a term coined to describe the phletora of websites that exists nowadays catering to Internet users to have a place where they can network and participate in a more interactive way. Examples of web 2.0 based are Flickr, where users can share photos, and Wikipedia, a place where users can help to contribute to an article’s content either by editing or adding to it.
And not forgetting, blogging is also included in the web 2.0 family. Compared to the conventional fashion of publishing, it allows readers to share their views by commenting on it. And recently there’s a discussion of the possibilty of the third wave to hit the web in near future, the web 3.0.
What exactly is web 3.0? It basically means web browsing with 3D experience. If Web 2.0 is built towards the social side of the online world, web 3.0 is expected to be where the money will be made by the corporations. Although it have existed for quite some time now, but the exposure is for web 3.0 based applications more towards focused groups. This is possible, thanks to the development of faster processors and hi-speed broadband access that keep on coming our way nowadays.
Web 3.0 based applications are expected to be a virtual reality location where consumers can try anything. An example would be the Second Life, where more than 1 million players, including offline merchants participate. I can’t wait to try out my new shirt virtually!
WHAT IS WEB 1.0, 2.0, AND 3.0
What do people mean when they talk about the Web 2.0?" is a query we receive repeatedly, and probably has as many answers as the number of people out there using the term. However, since talk about the Web 3.0 has surfaced in the last year or so, a whole new level of confusion seems to have set in. In an effort to help people understand the ideas behind buzzwords like Web 2.0 and Web 3.0, let's go through what exactly these terms mean (if anything), and how they apply to your ecommerce business.
A broad definition
I want to make it clear at the start that this article is meant to be a broad definition of the challenges that cause people to think in terms of Web 2.0 and Web 3.0. Since these are buzzwords and not clearly defined terms, think of this as an attempt to provide a bird's-eye view of the ever-changing lay of the land on the web. In an effort to create discreet "versions" of the web that can be compared, I will borrow from the W3C Director Tim Berners-Lee's notion of the read-write web, which is often used as a way of explaining what Web 2.0 means.
The first implementation of the web represents the Web 1.0, which, according to Berners-Lee, could be considered the "read-only web." In other words, the early web allowed us to search for information and read it. There was very little in the way of user interaction or content contribution. However, this is exactly what most website owners wanted: Their goal for a website was to establish an online presence and make their information available to anyone at any time. I like to call this "brick-and-mortar thinking applied to the web," and the web as a whole hasn't moved much beyond this stage yet.
Shopping carts are Web 1.0
Shopping cart applications, which most ecommerce website owners employ in some shape or form, basically fall under the category of Web 1.0. The overall goal is to present products to potential customers, much as a catalog or a brochure does — only, with a website, you can also provide a method for anyone in the world to purchase products. The web provided a vector for exposure, and removed the geographical restrictions associated with a brick-and-mortar business.
Currently, we are seeing the infancy of the Web 2.0, or the "read-write" web if we stick to Berners-Lee's method of describing it. The newly-introduced ability to contribute content and interact with other web users has dramatically changed the landscape of the web in a short time. It has even more potential that we have yet to see. For example, just look at YouTube and MySpace, which rely on user submissions, and the potenital becomes more clear. The Web 2.0 appears to be a welcome response to a demand by web users that they be more involved in what information is available to them.
Many views of Web 2.0
Now, it's important to realize that there are a staggering number of definitions of what constitutes a "Web 2.0 application." For example, the perception exists that just because a website is built using a certain technology (like Ruby on Rails), or because it employs Ajax in its interface, it is a Web 2.0 application. From the general, bird's-eye view we are taking, this is not the case; our definition simply requires that users be able to interact with one another or contribute content. Developers, for example, have a much more rigid definition of Web 2.0 than average web users, and this can lead to confusion.
This in turn leads us to the rumblings and mumblings we have begun to hear about Web 3.0, which seems to provide us with a guarantee that vague web-versioning nomenclature is here to stay. By extending Tim Berners-Lee's explanations, the Web 3.0 would be something akin to a "read-write-execute" web. However, this is difficult to envision in its abstract form, so let's take a look at two things I predict will form the basis of the Web 3.0 — semantic markup and web services.
Semantic markup refers to the communication gap between human web users and computerized applications. One of the largest organizational challenges of presenting information on the web is that web applications aren't able to provide context to data, and, therefore, can't really understand what is relevant and what is not. Through the use of some sort of semantic markup, or data interchange formats, data could be put in a form not only accessible to humans via natural language, but able to be understood and interpreted by software applications as well.
While it is still evolving, this notion — formatting data to be understood by software agents — leads to the "execute" portion of our definition, and provides a way to discuss web services.
Web 3.0
A web service is a software system designed to support computer-to-computer interaction over the Internet. Web services are not new and usually take the form of an Application Programming Interface (API). The popular photography-sharing website Flickr provides a web service whereby developers can programmatically interface with Flickr to search for images. Currently, thousands of web services are available. However, in the context of Web 3.0, they take center stage. By combining a semantic markup and web services, the Web 3.0 promises the potential for applications that can speak to each other directly, and for broader searches for information through simpler interfaces
What's important to understand, I think, is that the nomenclature with which we describe these differing philosophies should not be taken too seriously. Just because a website does not employ Web 2.0 features does not make it obsolete. After all, a small ecommerce website trying to sell niche products may not have any business need for users to submit content or to be able to interact with each other.
Most importantly, you don't need to upgrade anything, get new software or anything like that. These are abstract ideas used to contemplate the challenges developers face on the web in addition to theories about how to address them.
