Plural noun

The Open Definition !The Open Definition sets out principles that define “openness” in relation to data and content. !It makes precise the meaning of “open” in the terms “open data” and “open content” and thereby ensures quality and encourages compatibility between different pools of open material. !It can be summed up in the statement that:
!“Open means anyone can freely access, use, modify, and share for any purpose (subject, at most, to requirements that preserve provenance and openness).” !Put most succinctly: !“Open data and content can be freely used, modified, and shared by anyone for any purpose”

You must be able to re-use and re-distribute the data, including being able to mix it with other data sets
@sjenkinson
There should be no discrimination involved - for example data shouldn’t be limited to ‘non-commercial’, or only for education

“Start to explain the data in understandable terms, and to illustrate
some of the relationships in ways normal people can understand”

“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 Property narrows property results down, only showing you houses that fall within a decent commute time from the places you visit regularly - like work, school, or the shops.”

“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.”

“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.”

★ Make your stuff available on the Web (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 stuff.
★★★★★ Link your data to other data to provide context.
“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.”
