CASE STUDY: GRIDL

The GRIDL project works towards a distributed image processing system in support of virtual observatories for astronomy. The goal of the project was to develop a set of tools for accessing and manipulating of distributed astronomical data via IDL clients. To do so,...

A system for web services composition

Web services composition is one of the most prominent activities in service oriented software development. Composition means to build a composite web service with component web services [1]. The specification of the composition is done by modeling a low level business...

GENERATING USER INTERFACES FROM TASK MODELS

Service annotations can be exploited to significantly enhance the initial UI which is generated by the tranformation of interaction tasks into dialogs. Without annotations, the initial UI generated from a task model lacks suitable layout definitions, usability...

Improving Task-driven Software Development Approaches

The aspect of human interaction becomes more and more relevant for service-oriented applications. On one hand, current development approaches support the composition of services but neglect the creation of user interfaces. On the other hand, task-based modeling of...

Applying CBD to Web Services

The advent of component-based software engineering changes this situation by making available mechanisms that enable software elements, right down to the binary level, to be rapidly and efficiently assembled into new applications. This allows the basic tenet of...

JAVASCRIPT, CASCADING STYLE SHEETS

JAVASCRIPT JavaScript (JS or js) is a dynamic computer programming language [4]. It is added to an HTML page and used by the web browser to implement client-side (in the user’s browser) interaction, control the browser, communicate asynchronously, and alter the HTML...

Multiagent Querying of Semantic Web Resources

Multiagent Architecture For query functions, a set of multiagents is used generated from the INDEX environment described in [7]. Agents in this environment, unlike other agent systems such as those described in [5] and [6], work with a semantic knowledge base...

Web Site Management

The World Wide Web is expanding and its value is increasing as a method for locating and delivering information. This creates a significant engineering challenge. Locating applicable information requires that indexing information be incorporated into Web page...

Adaptation and Validation of the Design

Once the transformation process is completed the web expert can make use of AriadneTool in order to adapt the diagrams automatically generated from the IMS LD specification to comply with the web system requirement. These actions may range from: • The modification of...
