Where the desktop meets the web, we find the emerging category of rich Internet applications. Online, but with the smoother look and feel of desktop software, RIAs eliminate the slow loading of individual web pages by using tools such as JavaScript, Extensible Markup Language (XML), Adobe Inc.’s Adobe Integrated Runtime (AIM) and Microsoft Corp.’s Silverlight to create dynamic online applications that can even, in some cases, continue to work when offline.
Developer: Teknision Inc., Ottawa
Project: Finetune Desktop is the result of a collaboration between Teknision and NextRadio Solutions, a Newton, Mass., company set up by alumni of the original Napster to offer an internet radio service called Finetune. Teknision was first brought in to design the original Web music player interface for Finetune, then went on to other projects such as building interfaces for the PlayStation 3 and Wii game consoles. Finetune Desktop is a Web-based desktop music player that runs on Windows or Mac OS.
How it works: Teknision used AIR, Adobe’s development tool that allows RIAs to be extended to the desktop, to build Finetune Desktop. To use it, you have to download the Adobe AIR runtime to your PC or Macintosh. Finetune Desktop then lets you play music from Finetune as well as any music stored on your desktop computer, and search for music whether it is online or stored locally.
Best practices: Tony MacDonnell, Teknision’s chief technology officer, says one of the most important things to remember in building rich Internet applications is to make sure they behave properly. “When you’re inside someone’s sanctuary you have to play by the rules of that sanctuary,” he says.
MacDonnell doesn’t approve of RIAs that take over the PC’s entire screen without asking, or interfere with other applications. Finetune Desktop doesn’t act that way. “It’s job there is just to focus on doing what it does well — it’s playing music and then getting out of your way,” he says.
Developer: Nitobi Software Inc., Vancouver
Project: Nitobi Complete UI is a set of nine user interface components for rich Internet applications. They’re designed to help RIA developers save time by plugging in whichever Nitobi modules they need rather than recreating the functions themselves. They include, for example, a spreadsheet module called Grid, a Calendar module, and ComboBox, for completing data-entry fields by searching a database as the user types.
How it works: All the Nitobi Complete UI components are written in HTML and JavaScript. Nitobi has offered the components since 2004, but more recently has used Adobe AIR to give them the ability to work offline as well as online. That means users can transfer data between their desktops and the Web more seamlessly, says Andre Charland, Nitobi’s chief executive, and they can take data such as contact lists with them even when not connected to the Internet.
Best practices: If you take the time to understand what AIR can do, says Charland, “it’s amazing to me how close we can get to traditional desktop software.” The key is understanding and fully exploiting its capabilities.
For instance, he says, AIR can provide native access to Flash on the desktop, and it’s possible to call Adobe’s ActionScript directly from JavaScript.
Because AIR is still in beta, he notes, it remains a “moving target” for developers. Nitobi tries to deal with that by being very open with its customers about ways in which things could change.
Developer: TSOT Inc., Toronto
Project: FraternityLive and SororityLive are online, software-as-a-service systems to aid in the running of university fraternities and sororities. They include a financial component for budgeting and accounting, a shared calendar, communications tools, an organizational chart and Facebook-like social networking. TSOT launched FraternityLive and SororityLive, its first products, in January 2007. They currently have about 13,500 registered users, says Corina Newby, the company’s public relations officer.
