21st February is #OpenDataDay

21st February is International Open Data Day, a "gathering of citizens in cities around the world to write applications, liberate data, create visualizations and publish analyses using open public data to show support for and encourage the adoption open data policies by the world's local, regional and national governments." The Open data Handbook defines open data as follows "Open data is data that can be freely used, reused and redistributed by anyone - subject only, at most, to the requirement to attribute and sharealike." On 21st there are events such as hackathons, in various locations, such as Open Data Day London 2015. Some organisations are releasing data e.g. the UK's Natural History Museum "as part of International Open Data Day ... is opening up its digital collections and research data through its new Data Portal."
