The document discusses how to maximize the benefits of open data by maximizing its reuse. It identifies four key areas to focus on: legal, practical, technical, and social. Legally, data should have an unrestricted license and not contain private information. Practically, data needs to be timely, accurate, and reliably available. Technically, data should be machine-readable, in an appropriate format, and use open standards. Socially, there needs to be documentation, feedback mechanisms, community building, and tools to work with the data. The document concludes that simply focusing on format is not enough and these other areas also need attention to help people understand and easily work with the open data.
