Use Case and Functional Requirements.

The success of new innovations and technologies are very often disruptive in nature. At the same time, they enable novel next-generation infrastructures and solutions. These solutions often give rise to creation of new markets and/or introduce great efficiencies. For example, the standardization and deployment of IP networks resulted in introducing novel applications that were not possible in older telecom networks. The Web itself has revolutionized the way people look for information and corporations do business. Web-based solutions have dramatically driven down operational costs both within and across enterprises. The Semantic Web is being proposed as the next-generation infrastructure, which builds on the current Web and attempts to give information on the Web a well-defined meaning [2]. This may well be viewed as the next wave of innovation being witnessed in the information technology sector. [ABSTRACT FROM AUTHOR]
