ITU‐T's Technical Reports and Specifications 717 This report gives a specific description to three‐level system of nationality, state/province, and city. The government is in the core status, enterprise and social groups are the subjects of data resource exploitation and utilization. Data resource exploitation and utilization should increase public interest as a prerequisite and should not harm the privacy of owner's data source and national security. Open data is a kind of service system which has universal social significance. It is used not only to increase public welfare of social members, but also to enhance the competitiveness of a specialist area, or the competitiveness of the region. At the background of opennessgovernment and third‐party organizations should develop a win‐win cooperate mode, andthen jointly maintain and developopen data.Through the cooperation establishing a service network covering the whole of society to benefit the public, this can provide the basis for social development and transformation. Principles of business model for open data are government dominant, broad participation, and interactive sharing. There are three specific patterns: (1) Independent operation Independent operation pattern totally relieson the strength of government departmentsto operate web site. At present independent operation, pattern is often used in the government website, which requires sufficient human resources, financial guarantee, and technical support. However, this can give increasing fiscal burden to the government, and also is likely to cause technical problems and security technology due to lack of human resources. (2) Cooperative operation Cooperative operation pattern transfer some sections of the web site to third parties, not only ensures that government seize the initiative inthe central part, but also ensure that other organizations work on what they love and master by a third party. Thus it will be conducive to daily operations and update maintenance of open data, and to reduce the pressure of government staffs. In addition, to promote the development of value‐added utilization of data resources, it should encourage the participation of the private sector and non‐governmental organizations, simultaneously promote fair competition in the public and private sectors. Due to remarkable gap between governmental data resources and diverse demand of the general public, some of the data should be professional analysis and research because most userscan not directly use the original data resources provided by government. Through filtering, organizing, and then processing the original data resources, third‐party organizations can provide secondary use of data or services for individuals or other organizations to use, this can bridge the gap between demand and supply. (3) Outsourcing operation Outsourcing operation can improve the efficiency of maintenance management through guaranteed services of professional organizations, this is a good way to cost savings and boost industrial development. Meanwhile government has a distinct advantage and effects in efficiency improvement, structures implifies, costs reduction and professional services development. From now on, more and more open data projects gradually from independent operation pattern to cooperative operation pattern.
