“We observed that often people think of open data as a specific ‘kind’ of data – something separate and distinct from the data they use day-to-day in their organisation or team – rather than a choice about how people publish data.” theodi.org/blog/closed-shared-open-data-whats-in-a-name

Transparency @sjenkinson


Слайд 53

“…within two years chemical emissions nationwide (at least as reported, and presumably also in fact) had decreased by 40 percent. ! Some companies were launching policies to bring their emissions down by 90 percent, just because of the release of previously sequestered information.” maban.co.uk/80

DATA & USER EXPERIENCES


Слайд 56

“How far do you live from your workplace? Chances are, you'd answer that question in minutes rather than miles. ! An hour on the bus tells us a lot more than 47 miles. That's why we made Mapumental. ! Given any start point or destination, it'll show everywhere within the chosen commute time, by public transport.” mapumental.com/services/travel-time


Слайд 57

“How accessible is your nearest school, post office, or GP’s surgery? ! In Wales, that’s not always a simple question: the country’s mountainous landscapes, rural populations, and sometimes infrequent bus services can mean that those without cars are rather cut off from public service provision.” mapumental.com/services/accessibility


Слайд 58

“Just how quickly could fire engines reach a given postcode in case of a fire? ! It’s a question that’s pivotal to decisions made by both the emergency services and the insurance industry.” mysociety.org/2013/04/22/fire-fire-mapumental-and-fire-engine-journey-times

“Air Transformed is a series of wearable data objects that communicate this physical burden in different ways. Though seemingly decorative, they are based entirely on open air quality data from Sheffield, UK, a former steelmaking city and notorious for its bad air.” stefanieposavec.co.uk/data/#/airtransformed

★ ★★ ★★★ ★★★★ ★★★★★ Make your data available on the web (in whatever format) under an open license. Make it available as structured data (e.g., Excel instead of image scan of a table). Use non-proprietary formats (e.g., CSV instead of Excel). Use URIs to denote things, so that people can point at your data. Link your data to other data to provide context.
