It is expected that the release of a huge amount of public data owned by the national and local governments as open data will be a new driving force for technological innovation by private and non-governmental organizations.
However, many of the public data currently released cannot be processed like a PDF file, or can not be processed without relying on specific software such as spreadsheet, so it is suitable for machine interpretation and commercial purposes It is necessary to make it easy to process under secondary available rules including.
Therefore, by publishing these public data as open data in a format that is easy to process in advance, not only will it increase administrative transparency, but also provide public services through public-private collaboration such as application development, etc. It is thought that this will lead to the creation of services and employment, the promotion of efficiency in corporate activities, and eventually the economic revitalization of Japan as a whole.
