2. Overview Project Name : Client Repository name : Client
Project Description
This project is the UI presentation view of Open-O system, and has important features of strong expansibility and low dependence on operation system. The Client project provides visual operation function for users and implements the orchestrator network services by calling RESTful APIs of Open-O system.

4. Problem being Solved Strong extensibility of functional modules
The Client project can add or delete function modules more easily. Portal applications can be decoupled from each orchestrator so that developers can work independently and integrate function modules into the Client system for no-interference.
Low dependence on operation system
The Client project adopts HTML and Javascript technology to reduce dependence on operation system. Portal applications can be deployed to the web server more simply and implement orchestrator services by calling RESTful APIs.
Offering identical presentation style
The common module defines coherent presentation style for other functional modules as the framework of Client system. Function modules can import defined style without concern of details to give users a sense of uniformity.
Providing third-party software
The common module can import open source third-party software as developers need. It means that the third-party software can be managed by Client framework to avoid repeated import.

5. Problem Statement
OPEN-O Portal currently is not unified and no common framework is provided for the individual pages.
No rules and restrictions defined on UCD or usability.
Hence OPEN-O currently has a difference in look and feel between the pages from different partners.

6. GUI Single Dashboard
Main page for all the views needed for the OPEN-O User
Hop based interlinking between the different portals.
Easy to integrate the new portal pages and plug & play

11. Advantages
We will have the look and feel everywhere in the OPEN-O application
Easy to develop the Portal and will reduce the effort for the developers
There is a defined place for all the functionality and if any error occur, stabilizing is much faster
Even a non experienced person can use it better and can implement intended business logic
We will have extension scope much better, i.e., if required portability of the UI will be much better to a new technology.
