TOWARDS AN INTERNET-BASED MARKETPLACE FOR SOFTWARE COMPONENTS

摘要

Software components provide support for reusability, extensibility, and flexibility which are required in distributed application scenarios. Lately, a new kind of software component has attracted considerable attention, i.e. web services. A web service is a self-contained, self-describing modular application component that can be published, located and invoked across the web. We claim that this trend will lead to a "component marketplace" where software components are traded. Depending on the type of component and the application requirements the spectrum of component usage will range from purchasing and downloading a component as a whole to leasing and accessing a component over the Web. A market infrastructure is needed in order to dynamically offer, trade, bind and deploy software components.
