Among the plethora of JavaScript libraries to have been released, few have been recognised to be as effective as jQuery. This lightweight library has been the subject of different discussions since it was launched in 2006. Basically, jQuery has the ability to flawlessly string together JavaScript together with HTML. Because of its effectiveness, there have different types of lightweight applications and plug-ins launched using jQuery. Ajax based websites that offers simple interface would virtually work together using jQuery’s simple interface.

The ActionScript reference for rich Internet application development provides an alphabetical reference for all native ActionScript APIs for the Adobe technology platform runtimes: Adobe Flash Player and Adobe AIR—as well as the Adobe Flex framework APIs. Use this guide both as an API reference and a tool to learn about the ActionScript APIs available within the runtimes.

The Adobe technology platform contains two primary runtimes. Flash Player is browser-based, and Adobe AIR is desktop-based. Because Adobe AIR is built on top of Flash Player, the Flash Player APIs are available within Adobe AIR. Consequently, Adobe AIR APIs are not available within Flash Player. The Flex framework is built on top of the Flash Player APIs, so it runs in both Flash Player and Adobe AIR. However, a number of Flex APIs take advantage of AIR APIs, and thus work only within Adobe AIR.

On the Web, a walled garden is an environment that controls the user’s access to Web content and services. In effect, the walled garden directs the user’s navigation within particular areas, to allow access to a selection of material, or prevent access to other material.

Recent history suggests that open standards will again better the “walled gardens” of the Web.

In 1994, when the previously obscure computer network, developed by the American Department of Defence, first become known to the general public as the “World Wide Web”, or simply The Web, many people first connected to it via AOL and CompuServe. These subscription-based service providers offered not only access to the Internet, but other services such as email, chatrooms, discussion boards and more. It was access to the Web via the Internet that would lead to the undermining of these services, and the opening up of the Web as a platform for individual and creative expression, revenue generation and social interactivity.

Whilst it took some time for the closed communities to venture out into the wilds of the Web, it brought about the standardisation of the services that made up the early web. For instance, POP and SMTP standardised email and as a result it has become the ubiquitous tool of business. Today, of the early pioneers of the Web, only AOL survives, but as an entirely different entity; a web portal supported by advertising.

History appears to be repeating itself. The biggest online phenomena of the past couple of years, the social-networking websites of Facebook and MySpace, are acting very much like the AOL of the mid-1990s. They are closed systems based upon prioprietory standards. You cannot easily move information from one system or another if you so choose. This ties users into one system, or forces them to create profiles on both. A similar comparison can be drawn with the virtual worlds of Second Life and Entropia Universe.

The Web is better when it’s social.

Part of the reason these websites are popular is because they are closed communities, where users can interact with friends and find new friends with which to interact. This community feel has been tested in recent times, with sites such as Facebook being criticised for using their user’s personal data to target advertising. It is innevitable, however, that these systems are proprietory; it is only once these systems immerge and become popular that standards can be developed and implemented.

Just as the Web’s open standards, embodied in the Netscape browser, displaced the online services providers, so the paradigm of open standards awaits the social networking and virtual worlds. Back in the 1990s it was Netscape, but in the 21st Century it falls to Google to defend the open standards of the Web with the Open Social API. Some say there is a large amount of self interest in this move, since Facebook and MySpace have huge communities, which both networks know a huge amount more about than Google and can hence generate billions of dollars of revenue.

The web is more interesting when you can build applications that easily interact with your friends and colleagues. But with the trend towards more social applications also comes a growing list of site-specific APIs that developers must learn. Open Social is an attempt not only to open up the closed communities and allow developers to interact with the different networks, but allow developers to only learn one API. MySpace has signed up to this initiative and, more reluctantly so has Facebook. A curiosity is AOLs recent aquisition of Bebo, another online community popular in Europe. Is AOL simply jumping on the “band-wagon”? Has it learnt its lessons of the past, or is it using knowledge of its past as a guiding principle? Whatever is the answer, Bebo’s inclusion in Open Social will help it continue its competition with other social networking websites.

A new breed of Web-based data integration applications is emerging across the Internet. Colloquially known as “mashups”, their popularity stems from the emphasis on interactive user participation and the manner in which they aggregate third-party data.

A mashup is a website or web application that seamlessly combines content from more than one source into an integrated experience.

Mashups are an exciting genre of interactive Web applications that are characterised by, and draw upon, content and functionality retrieved from external data sources to create entirely new and innovative services. They are a hallmark of the second generation of Web applications widely known as Web 2.0.

This vague data-integration definition of a mashup certainly isn’t a rigorous one. A good insight as to what makes a mashup is to look at the etymology of the term:

Mashup, or bastard pop, is a musical genre which, in its purest form, consists of the combination (usually by digital means) of the music from one song with the a cappella from another. Typically, the music and vocals belong to completely different genres. At their best, bastard pop songs strive for musical epiphanies that add up to considerably more than the sum of their parts.

Like these songs, a mashup is an unusual or innovative composition of content (often from unrelated data sources), made for human (rather than computerized) consumption.

Mapping mashups

In this age of information technology, people are collecting a immense amount of data about things, activities, events, all of which can be annotated with locations. These diverse data sets that contain location data, are wanting to be presented graphically using maps. One of the big catalysts for the advent of mashups was Google’s introduction of its Google Maps API. This opened the floodgates, allowing Web developers to mash all sorts of data (everything from nuclear disasters to Weather Bonk and Keotag) onto maps. Not to be left out, APIs from Microsoft (Virtual Earth), Yahoo (Yahoo Maps), and AOL (MapQuest) shortly followed.

Video and photo mashups

The emergence of photo hosting and social networking sites like Flickr with APIs that expose photo sharing has led to a variety of interesting mashups. Because these content providers have metadata associated with the images they host (such as who took the picture, what it is a picture of, where and when it was taken, user-defined tags for describing the image and more), mashup designers can mash photos with other information that can be associated with the metadata. For example, a mashup might analyse song or poetry lyrics and create a mosaic or collage of relevant photos, or display social networking graphs based upon common photo metadata (subject, timestamp, and other metadata.). Yet another example might take as input a Web site (such as a news site like CNN) and render the text in photos by matching tagged photos to words from the news. EducationSearch is an education search tool which enables you to search by: Location, Career, Industry/Salary and provides personalized searches to save for future reference. EducationSearch Utilises Flickr, Google Maps and YouTube.

Search and Shopping mashups

Search and shopping mashups have existed long before the term mashup was coined. Before the days of Web APIs, comparative shopping tools such as BizRate, PriceGrabber, MySimon, CrowdStorm, Shopping.com and Google’s Froogle used combinations of business-to-business (B2B) technologies or screen-scraping to aggregate comparative price data. To facilitate mashups and other interesting Web applications, consumer marketplaces such as eBay and Amazon have released APIs for programmatically accessing their content.

News mashups

News sources (such as the New York Times, the BBC, or Reuters) have used syndication technologies like RSS and Atom since 2002 to disseminate news feeds related to various topics. Syndication feed mashups can aggregate a user’s feeds and present them over the Web, creating a personalized newspaper that caters to the reader’s particular interests. An example includes Diggdot.us, which combines feeds from the techie-oriented news sources Digg.com, Slashdot.org, and Del.icio.us. This is in contrast to Google News which aggregates news content through complex search algorithms.

Mashups represent huge benefits and challenges to software companies. No longer is the web simply a collection of web pages that a user ’surfs’ through on a day to day basis. The web is becoming an omnipotent tool, a global application along the mold of Microsoft’s Windows OS. People are learning to develop Web 2.0 with much the same energy as seen in the early innovations of the personal computer market. The more people seize control of this new paradigm, the more the long-delayed promise of software and services that can be tapped on demand is realised.

At the same time these bottom-up efforts represent a tough challenge to the service providers upon which the mashup is based. Mashups often use data with out licence, and present this data in unintended ways. For example, Yahoo initially blocked the use of its API by one mashup website that was using it’s content in conjunction with the Google Maps API. Amazon blocked the use of it’s API by Amazon Light until it changed how it linked to rival sites and the GreaseMonkey extension for the Firefox Browser, which allows the quick installation of scripts to manipulate web pages, represents a security threat if exposed to malicious scripts.

Inexpensive Research & Development

Amazon and other giants in the web business are embracing the mashup phenomenon by allowing easier access to their data services. Indeed, these companies are programming their interfaces so that much of the computations are made on the client’s computer rather than a server located on potentially another continent. This allows developer’s to make their own tweaks.

The appeal to web sites is clear. Mashups represent a way to develop creativity, software, tools and communicate messages to the community.

However, mashup business models don’t extend beyond running a few Google ads and collecting fees for sending buyers to e-commerce sites. One reason is that most Web sites don’t allow for-profit use of their data by outsiders. But as traffic to mash-ups grows, companies may cut deals, especially if mash-up sites spur new markets. Map-based mash-ups, for instance, may finally attract local businesses to advertise on the Web.
