    22. 22. 8Linked Data Principles http://www.w3.org/DesignIssues/LinkedData.html• Use URIs as names for things • e.g., file:///Users/admin/wwu.png• Use HTTP URIs so that people can look up thosenames • e.g., http://www.uni-muenster.de• When someone looks up a URI, provide usefulinformation, using the standards (RDF*, SPARQL) • e.g., http://www.uni-muenster.de foaf:name „Westfälische Wilhelms-Universität Münster“

    31. 31. 12LODUM Linked Open Data University of Münster
    32. 32. 12LODUM Linked Open Data University of Münster• Provide scientific and educational data as Linked Open Data• Open up and interlink existing data• Provide data through a standardized interface for application developers
    33. 33. 13LODUM Linked Open Data University of Münster• Goals: • Increase WWU‘s visibility • Foster transdisciplinary research • Improve access to and management of existing data• Interlinking 5+3 Ps: • People, publications, projects, prices, patents (→CRIS) • Properties, places, periods
    34. 34. 14Beyond the tech stuff• Comprehensive transparency strategy• Establish workflows to make data, models, software etc. that are used in a publication available• Push Open Access publishing• Following recommendations of the German Research Council• Steering committee for high-level administration• Long-term initiative for the next decade
    35. 35. 15WWU Data governance strategy1. Create Incentives (for research and teaching)2. Lower the barriers (technical, economic, legal, institutional)3. Staged licensing model, ranging from confidential to Creative Commons / ODbL4. Rules for publishing scientific data and models5. Reversal of the „burden of proof“, requiring justification for data that are not published

    39. 39. 17Linking disconnected datasets• Conversion to RDF is easy• But: How to find data about the same real-world things in other datasets? •Names are ambiguous• Space-time is an excellent data integrator: something cannot be in two different places at the same time
