South Korea's policies and efforts to enable publicly-available government data to be easily accessible still has a long way to go with the country coming in 12th among the surveyed 77 nations, data showed on Wednesday.

The so-called Open Government Data Barometer ranked Britain as the most advanced country for open data readiness, implementation and impact with a score of 100. The United States came in second with a score of 93.38, followed by Sweden with 85.75 and New Zealand with 74.34, according to the index compiled by World Wide Web Foundation, established by Tim Berners-Lee, inventor of the Web.

South Korea's score was 54.21.

South Korea earned good marks in the open data readiness-sub index at 77, but ranked lower than other countries in implementing open government data projects with a score of 55.

The foundation said open government data policies have seen rapid diffusion over the past few years, reaching over 55 percent of the countries surveyed in the Barometer, with such policies taking a range of different forms.

"Although open government data policies have spread fast, the availability of truly open data remains low, with less than 7 percent of the dataset surveyed in the Barometer published both in bulk machine-readable forms, and under open licenses," it said. (Yonhap News)
