I will present status in my phd study, which is a part of websys project.

2. Background My Ph.D. work is a part of WEBSYS project Main goal:
develop guidelines for the industrial development of timely and reliable Web-based systems
Sub-goals:
Better understanding of the software process and related technologies on how to make trade-off between time-to-market (TTM) and reliability;
Contribute to better methods and techniques for Web-based systems development where reliability and TTM need to be considered together;
Dissemination and exchange of the gained knowledge, with a strong international component
Background for my pdh study is clear from the beginning. As described in the websys project description,

3. Research theme Technology and operation modes
Reliability and robustness requirement
Time-to-market requirement
Web-based system development process
Empirical study
According to the project description and defined goals, my research theme covers at least five dimensions:
By combination of these five dimentions, can produce a large number of relevant topics. I have used time in the beginning to find out focus things. And temporary I have planned to do the following things

4. A top-level refernce model
Interface
How web pages look and feel (layout, JavaScript)
Navigation
Facilitate navigation functionality
Web
components
Controller
User Request processing
in the architectural framework each layer is futher composed of components to implement required functionality, and the components within each layer interact with each other to provide services to the upper layer, and components in different layer interact together to provide services to the user of the system.
The components in the first three layers are called web components because they provide functionality associated with a web site and hypermedia application, the components in the other two layers are middle tier components as they provide traditional software functionality such business logic.
Model
Business logic and application data
Middle tier
components
Infrastructure
Middleware support

5. Activity next 6 months Robustness metrics
Completion of the definition
Propose of metrics
Planning validation study
Extension of the refernce model
Modeling and integration
Identify and categorize components, patterns and other artifacts to improve reuse
How to insert robustness
How to integrate with the development process
