The WebComposition approach itself does only describe the development and evolution process, and the concept of composing and reusing Web components, but does not address the concrete implementation technology. Earlier systems realizing the WebComposition approach used object-oriented technology (WWW6- version in Java in 1997), XML-component descriptions (WebComposition Markup Language in 1998), or component- and service-oriented technology (WebComposition Service Linking System in 2003). Based on this experience, we introduce the next generation of a Web component that is addressing the content (data and semantics) perspective, which addresses the implementation technology aspect with an implementation independent approach.

This set of sample application and documentation deomonstrates how to install, set up and use the WebComposition/DGS. The documentation covers the topics

  • Install the WebComposition/DGS
    The WebComposition/DGS is easy to deploy. Read the documentation that describes the steps necessary to install the service.

  • Setup your environment
    Following a few steps your system can be prepared to run the WebComposition/DGS. Read the documentation to learn how to set up your environment to run the Webcomposition/DGS. The documentation shows how to set up Windows XP, Windows Vista, Windows Server 2003 as well as Windows Server 2008.

  • Configure the WebComposition/DGS
    Configuring your instance of the Webcomposition/DGS is easy and flexible. Read the documentation to learn how to configure the service in a declarative manner.

  • The REST interface
    For easy reuse in a Web 2.0 the WebComposition/DGS follows a RESTful-style architecture. The corresponding REST interface is flexible easy to use. Read more about the design of the REST interface of the WebComposition/DGS.

  • The SOAP interface
    For complex business scenarios the WebCompositoin/DGS provides a WS-* conform SOAP interface, incorporating security eapsects by applying the IdFS approach for fullfill today's business needs. Read more about the design of the SOAP interface of the WebComposition/DGS.

  • The XML-RPC interface
    The WebComposition DataGridService staisfies the needs of a wide range of users, from beginners and rapid prototypeing up to up to professionals with high requirements on the system architecture and extensibility. The XML-RPC interface is a SOAP-based interface that allows especially intermediate and beginner users to interact with the WebComposition/DGS.

  • Semantic publish/subscribe
    A major collaboration features of the WebComposition/DGS is its semantic publish/subscribe mechanism that allows to notify participants about important events within the system.

  • API documentation
    The API deocumetnation is provided especially for Software and Web engineers that want to develop further solutions based on the WebCompositoin/DGS approach. The avaialble WebCompostion/DGS implementation is entirely written based on Microsoft's .NET platform 3.5 using the C# language.

  • Extending the service
    Extending the WebComposition DataGridService is easy. The architecture of the WebComposition/DGS approach provides various hotspots where developers can extend an existing implementation to adapt the solution to their spedific needs. Read the documentation to learn how to extend the service with your own components.

  • Demos
    Operating the WebComposition/DGS can be performed on a various of ways. Read through the documentaton to learn how to operate the WebComposition DataGridService and try out the live demos by selecting the topics below.
