Development of XML-based software and service commerce language XSCL and JavaBeans player

We propose the XML-based component commerce language XSCL (eXtensible Software specification and Commerce Language) and JavaBeans Component Player. ESD (Electronic Software Distribution) and ASP (Application Service Provider) are gaining ground in software distribution and provision. However, the representations of software/service specification and commerce information vary vendor by vendor. It is indispensable to provide a common representation of software/service specification and commerce in order to properly understand and compare software, services and software components. Furthermore, it is still difficult to specify the complex dynamic behavior and various non-functional aspects of software. Thus, it is helpful for the potential users of software to provide a tool to remotely exercise the software at his/her computer over the Internet. We developed the SCB (Software/Service Commerce Broker) on which we can provide a digital catalog of software with a HTML-based language SCL (Software specification and Commerce Language) and Component Player. Although it was effective in trial use, the representation capability is relatively weak due to the low-level representation capability of HTML. Thus, we developed the new language XSCL (eXtensible SCL) based on XML and accompanied JavaBeans Player
