ITU‐T's Technical Reports and Specifications 689 A summary of the main criteria for open data include: Availability and access: The data must be available as a whole and at no more than a reasonable reproduction cost, preferably by downloading over the internet. The data must also be available in a convenient and modifiable form. Re‐use and redistribution: The data must be provided under terms that permit re‐use and redistribution including the intermixing with other datasets. Universal participation: Everyone must be able to use, re‐use and redistribute. There should be no discrimination against fields of endeavor or against persons or groups. For example, 'non‐commercial' restrictions that would prevent 'commercial' use or restrictions of use for certain purposes (e.g., only in education), are not allowed. The idea of open government has an older origin, dated back to the early years following World War II at the time of the Great Depression in the U.S. There were increasing efforts to improve openness and the application of the right to know principle in the government during that period4 . The various components of open data as applied by national government and the private sector are discussed in this section. Though the term \"open data\" is not as old as open government. Open government data (OGD) is an important part of open data, which can be traced back to the 2003 Public Sector Information Directive by The European Commission5. As of January 2014, more than 700,000 OGD datasets have been put online by national and local governments from more than 50 countries. The first one‐stop‐shop open data portal Data.gov (www.data.gov) was launched in May 2009, as part of the open government directive of the Obama Administration. In the Memorandum on transparency and open government, issued on January 21, 2009, the President instructed the Director of the Office of Management and Budget (OMB) to issue an Open Government Directive. Responding to this memorandum is intended to direct executive departments and agencies to take specific actions to implement the principles of transparency, participation, and collaboration set forth in the President's Memorandum6. By June 2014, the US open government data portal has already published 104779 datasets in a machine‐readable format with 80486 geographical sets, 24293 non‐geographical sets and additional 341 tools. In January 2010, the British government launched Data.gov.uk. The British open data portal applied Comprehensive Knowledge Archive Network (CKAN), which is an open‐source data management system (DMS) for powering data hubs and data portals. Thus, both open government and open data initiatives are not entirely a new concept. At the conceptual level, the idea of openness has not significantly changed. For instance, the definition of open data in the current context still includes several important elements characterizing the preceding definition such as accessibility, availability, re‐usability, re‐distribution ____________________ 4 Li Ding , Timothy Lebo, John S.
