  • You’re likely sitting on a treasure chest …
  • … and the treasure is the data: - about energy usage, election data, products, geographical data, flights, development data, emissions, water quality, waste management, planning applications, education, etc.
  • But people don’t like data, what people like and use are applications. Applications produce, consume, manipulate, distribute, store, search, access … and sometimes destroy data.
  • But how do we get applications out of the data, and, for starters … how do we get the data?
  • Who of you knows this fellow here? I’d like to think of him as a data superstar. His name is Hans Rosling and he is a Swedish guy who deals mainly with statistical data.He coined a term for this problem: the so called database hugging disorder.Meaning: people and institutions, even if they are aware of their data, tend to not share it or hide it in applications.
  • Tim Berner’s Lee 5-star plan …★ Make your data available on the Web under an open license★★ Make it available as structured data(Excel sheet instead of image scan of a table) ★★★ Use a non-proprietary format (CSV file instead of an Excel sheet) ★★★★ Use Linked Data format (URIs to identify things, structured data such as in microdata, Atom/OData, RDF to represent data)★★★★★ Link your data to otherpeople’s data to provide context
  • Stepwise migration from inaccessible, locked-down data sources to open, publicly available, structured and ‘pre-integrated’ data sources.
  • So, how do we really get there? How do we get the data out of the wallet gardens?
  • People need to be able to come together (also virtually) and exchange thoughts, ideas, etc.
  • … they need to see what others do about it.
  • Where do we get the data from?
  • You might be lucky and find already some data,for example, via http://ie.ckan.net/
  • … or local data catalogs …
  • … but typically you need to invest a bit into freeing the data ;)
  • And how do we make the data available?
  • You might need to think about in which format you make your data available … there are quite some to choose from.
  • And of course you’ll need some tools for cleaning and publishing the data …
  • But there is another problem we’re facing … how to represent and exchange the terms we’re talking about …
  • No matter if we’re looking at the public sector or in the industry … we need to express the terms and the relationships between the terms
  • Schema.org, introduced in June 2011 by the ‘big three’, mainly for SEO …
  • A collection of terms (some 300 concepts and 200 properties or relations between the concepts)
  • Ah, and don’t forget … we’re talking about OPEN data, so a clear license does matter.
  • What’s next? Build applications!
