Web 3.0, When Web Sites Become Web Services



Today’s Web has terabytes of information available to humans, but hidden from computers. It is a paradox that information is stuck inside HTML pages, formatted in esoteric ways that are difficult for machines to process. The so called Web 3.0, which is likely to be a pre-cursor of the real semantic web, is going to change this. What we mean by ‘Web 3.0’ is that major web sites are going to be transformed into web services – and will effectively expose their information to the world.

The transformation will happen in one of two ways. Some web sites will follow the example of Amazon, and Flickr and will offer their information via a REST API. Others will try to keep their information proprietary, but it will be opened via mashups created using services like Dapper, Teqlo and Yahoo! Pipes. The net effect will be that unstructured information will give way to structured information – paving the road to more intelligent computing. In this post we will look at how this important transformation is taking place already and how it is likely to evolve.

The Amazon E-Commerce API – open access to Amazon’s catalog
We have written here before about Amazon’s visionary WebOS strategy. The Seattle web giant is reinventing itself by exposing its own infrastructure via a set of elegant APIs. One of the first web services opened up by Amazon was the E-Commerce service. This service opens access to the majority of items in Amazon’s product catalog. The API is quite rich, allowing manipulation of users, wish lists and shopping carts. However its essence is the ability to lookup Amazon’s products.
Why has Amazon offered this service completely free? Because most applications built on top of this service drive traffic back to Amazon (each item returned by the service contains the Amazon URL). In other words, with the E-Commerce service Amazon enabled others to build ways to access Amazon’s inventory. As a result many companies have come up with creative ways of leveraging Amazon’s information – you can read about these successes in one of our previous posts.

The rise of the API culture
The web 2.0 poster child,, is also famous as one of the first companies to open a subset of its web site functionality via an API. Many services followed, giving rise to a true API culture. John Musser over at programmableweb has been tirelessly cataloging APIs and Mashups that use them. This page shows almost 400 APIs organized by category, which is an impressive number. However, only a fraction of those APIs are opening up information – most focus on manipulating the service itself. This is an important distinction to understand in the context of this article.

The API offering today is different from Amazon’s one, because it does not open the database to the world. What it does do is allow authorized mashups to manipulate the user information stored in For example, an application may add a post, or update a tag, programmatically. However, there is no way to ask, via API, what URLs have been posted to it or what has been tagged with the tag web 2.0 across the entire database. These questions are easy to answer via the web site, but not via current API.

Standardized URLs – the API without an API
Despite the fact that there is no direct API (into the database), many companies have managed to leverage the information stored in Here are some examples…

Delexa is an interesting and useful mashup that uses to categorize Alexa sites. For example, here are the popular sites tagged with the word book:

Another web site called uses to recommend similar sites. For example, here are the sites that it thinks are related to Read/WriteWeb.

So how do these services get around the fact that there is no API? The answer is that they leverage standardized URLs and a technique called Web scraping. Let’s understand how this works. In, for example, all URLs that have the tag book can be found under the URL; all URLs tagged with the tag movie are at; and so on. The structure of this URL is always the same:[TAG]. So given any tag, a computer program can fetch the page that contains the list of sites tagged with it. Once the page is fetched, the program can now perform the scraping – the extraction of the necessary information from the page.

How Web Scraping Works
Web Scraping is essentially reverse engineering of HTML pages. It can also be thought of as parsing out chunks of information from a page. Web pages are coded in HTML, which uses a tree-like structure to represent the information. The actual data is mingled with layout and rendering information and is not readily available to a computer. Scrapers are the programs that “know” how to get the data back from a given HTML page. They work by learning the details of the particular markup and figuring out where the actual data is. For example, in the illustration below the scraper extracts URLs from the page. By applying such a scraper, it is possible to discover what URLs are tagged with any given tag.

Dapper, Teqlo, Yahoo! Pipes – the upcoming scraping technologies
We recently covered Yahoo! Pipes, a new app from Yahoo! focused on remixing RSS feeds. Another similar technology, Teqlo, has recently launched. It focuses on letting people create mashups and widgets from web services and rss. Before both of these, Dapper launched a generic scraping service for any web site. Dapper is an interesting technology that facilitates the scraping of the web pages, using a visual interface.

It works by letting the developer define a few sample pages and then helping her denote similar information using a marker. This looks simple, but behind the scenes Dapper uses a non-trivial tree-matching algorithm to accomplish this task. Once the user defines similar pieces of information on the page, Dapper allows the user to make it into a field. By repeating the process with other information on the page, the developer is able to effectively define a query that turns an unstructured page into a set of structured records.

The net effect – Web Sites become Web Services
Here is an illustration of the net effect of apps like Dapper and Teqlo:

So bringing together Open APIs (like the Amazon E-Commerce service) and scraping/mashup technologies, gives us a way to treat any web site as a web service that exposes its information. The information, or to be more exact the data, becomes open. In turn, this enables software to take advantage of this information collectively. With that, the Web truly becomes a database that can be queried and remixed.

This sounds great, but is this legal?
Scraping technologies are actually fairly questionable. In a way, they can be perceived as stealing the information owned by a web site. The whole issue is complicated because it is unclear where copy/paste ends and scraping begins. It is okay for people to copy and save the information from web pages, but it might not be legal to have software do this automatically. But scraping of the page and then offering a service that leverages the information without crediting the original source, is unlikely to be legal.

But it does not seem that scraping is going to stop. Just like legal issues with Napster did not stop people from writing peer-to-peer sharing software, or the more recent YouTube lawsuit is not likely to stop people from posting copyrighted videos. Information that seems to be free is perceived as being free.

The opportunities that will come after the web has been turned into a database are just too exciting to pass up. So if conversion is going to take place anyway, would it not be better to rethink how to do this in a consistent way?

Why Web Sites should offer Web Services
There are several good reasons why Web Sites (online retailers in particular), should think about offering an API. The most important reason is control. Having an API will make scrapers unnecessary, but it will also allow tracking of who is using the data – as well as how and why. Like Amazon, sites can do this in a way that fosters affiliates and drives the traffic back to their sites.

The old perception is that closed data is a competitive advantage. The new reality is that open data is a competitive advantage. The likely solution then is to stop worrying about protecting information and instead start charging for it, by offering an API. Having a small fee per API call (think Amazon Web Services) is likely to be acceptable, since the cost for any given subscriber of the service is not going to be high. But there is a big opportunity to make money on volume. This is what Amazon is betting on with their Web Services strategy and it is probably a good bet.

As more and more of the Web is becoming remixable, the entire system is turning into both a platform and the database. Yet, such transformations are never smooth. For one, scalability is a big issue. And of course legal aspects are never simple.

But it is not a question of if web sites become web services, but when and how. APIs are a more controlled, cleaner and altogether preferred way of becoming a web service. However, when APIs are not avaliable or sufficient, scraping is bound to continue and expand. As always, time will be best judge; but in the meanwhile we turn to you for feedback and stories about how your businesses are preparing for ‘web 3.0’.
