Quick GuidesHow to Open up
Data? Two key rules for opening up data • Start out fast, small and simple Keep it simple • Start out with a plan to open up just one dataset, • or even one part of a large dataset is fine • Engage with actual and potential users and reuses Engage early of the data and • The primary users can deliver data to ultimate users engage often by transformation, remix, or distribution. 17
A quick method4 Main Steps
for Opening Up Data 1. Choose dataset(s) • the dataset(s) you plan to make open 2. Apply an open license • Determine what intellectual property rights exist in the data • Apply a suitable „open‟ license that licenses all of these rights and terms of conditions 3. Make the data available • in bulk and in a useful format or APIs 4. Make it discoverable • post on the web and organize a central catalogue to list your open datasets 18
OverviewWorld Wide Web.. the universe
of network-accessible information, an embodiment of humanknowledge using standard protocols HTTP URI HTML Hypertext Transfer Protocol Uniform Resource Identifier HyperText Markup Language : the foundation of data : representations of the : the predominant markup communication for the Web resource over the Web language for web pages 20
DefinitionLinked Data … refers to
a set of best practices for publishing and connecting structured data on the Web using URIs, HTTP and RDF. Web of Data HTTP URI RDF Hypertext Transfer Protocol Uniform Resource Identifier Resource Description Framework : the foundation of data : representations of the : the standard markup language communication for the Web resource over the Web for the Semantic Web 28
OverviewGrowth of Interlinks… Linked Data
provides the means to reach the goal of the Semantic Web – “theemergence of a Web of Data” 2007-05-01 2007-10-08 2007-11-10 2008-02-28 2008-03-31 2008-09-18 2009-03-05 2009-03-27 2009-07-14 2010-09-22 29
Quick GuidesLinked Data Ingredients 1.
Things have names (a person, a city, a company) 2. Let these names start with http:// • then we can get more data about things using standard protocol • others can directly point to things in my dataset (and vice-versa) 3. Represent data (relations among things) as a labeled graph • do it by using a standard format (RDF) 31

5 plan for open government
data ★ Put your data on the WebStars ★★ Make it available as machine readable ★★★ Use open, standard formats ★★★★ Use a open data format – URLs, descriptions ★★★★★ Link your data to other people‟s data 40
SummaryOpen Data, Government Data, and
the Semantic Web “Hope is not the best action” Open Government Data is cost-effective tool for governments to improve service to citizens, civil society and business. Government data with Linked Data technologies will interconnect different datasets across local governments, organizations, or nations with social communities. Participation, participation, and participation. We need to design our future. 41
