 Simplicity

There is no requirement that every dataset must be madeopen right now. Starting out by opening
up just one dataset, or even one part of a large dataset, is fine – of course, the more datasets one
can open up the better. Remember, moving as rapidly as possible is good because it means one can
build momentum and learn from experience – innovation is as much about failure as success and
not every dataset will be useful.
 Maintainability

Maintainability involves a system of continuous improvement – learning from the past in order to
improve the ability to maintain systems, or improve reliability of systems based on maintenance
experience. In other words, the maintainability of the system expressed as the probability that a
system will be retained in or restored to a specified condition within a given period or expressed as
the actual operating costs of the system. The availability of the system can be reflected from two
aspects: hardware and software. Hardware equipment should be convenient for installation and
upgrade; it should also have sufficient spare parts. Software should provide flexible and user‐
friendly admin interface for operators.
 Security

Security provides "a form of protection where a separation is created between the assets and the
threat." These separations are generically called "controls," and sometimes include changes to the
asset or mitigate the threat. Generally, it is useful to ensure absolute security through permissions
setting, security certifications, anonymization technique and other means.

 Advancement
Advancement is responsible for maintaining the data in advance client/server(C/S), and relations
database. This responsibility involves processing all data and keeping the data in database current.
The system will use object‐oriented design; use the web access technology in user interface design
and then fully guarantee the requirements of application systems design and development.

3.2 The framework of overall design

The framework of open data is presented in the following Figure 1. The top layer consists of
applications of data products to meets public need. The second layer is a one‐shop portal providing
services including data catalog, data services, app services, developer center, service center and
map service. The third layer, which is the technology layer, consists of anonymization technique,
meta data management, linked data technique, data visualization and social network technique.
The fourth layer is open data management, with user management, quality management, security
management and operation management. The original data comes from government, social groups,
enterprise, and individuals. On the two sides of the framework, open data regularities and open
data security system protect the security and privacy of data.
