Smart Space Software Development Kit (SDK), which works with Microsoft Visual Studio 2005, is used to create custom gadgets and services using Microsoft Visual Studio 2005. The SDK provides a client-side object model in a .NET WinForms environment with code templates in Visual Basic and C#. Smart Space services are like gadgets but they have no user interface. Smart Space services can be called from other gadgets and services. In addition, messaging libraries are available in both .NET and Java as well as through a web service. The libraries enable an external application to send messages to and receive messages from (.NET and Java libraries only) Oracle Smart Space, Fusion Edition, users' contact list.

Gadget Development

Smart Space gadgets are lightweight, specialized mini-applications that can be placed anywhere on a user's Windows desktop.Various, pre-built gadgets ship with Smart Space. In addition, custom gadgets can be built to provide access to core Smart Space functionality and to the custom features available through third-party Smart Space services or the .NET Framework. Custom gadgets are created using the Smart Space Development Kit (SDK), which integrates seamlessly into Microsoft Visual Studio 2005 and, thereby, by providing C# and Visual Basic project templates and integrated help.

Service Development

Services enable splitting the implementation between user interface (UI) and non-UI components. Multiple gadgets can use one service. The gadget layer (UI) can reuse the service layer components (non-UI). Developers can extend the Smart Space framework by creating services others can use with their own custom gadgets or services.
