  1. The Registration Agency, DDI andLinked Open Data EDDI 2011 Nicole Quitzsch, Erdal Baran GESIS – Leibniz Institute for the Social Sciences

  2. History of the GESIS-Archive • Over 50 years • DBK = Data Catalogue of the Archive • DBK schema was developed long before DDI  DDI compatible

  3. Future

  4. Simplicity • Da|raismemberofDataCite • Da|raandDataCiteorientedto DDI andcontainedsuggestionsfrom DDI • Da|ra important elements from DDI and integrated them into our metadata schema

  5. Mapping • Data sets of independent, heterogeneous systems must be mapped to a common data format • Mapping only works if metadata formats are interoperable

  6. Mapping da|ra 2.2 to DDI 3.1 Da|ra mandatory properties:

  7. Mapping Problems Information Lost

  8. Mapping problems

  9. Metadata interoperability • DDI 3.1 can hold da|ra mandatory metadata properties • Da|ra 2.2 metadata schema is compliant with the DDI 3.1 standard

  10. Conclusion

  11. What is Linked Open Data (LOD)? • Linked Data Principles* • Use URIs asnamesforthings • Use HTTP URIs so thatpeoplecanlookupthosenames • Whensomeonelooksup a URI, provideusefulinformation, usingthestandards (RDF*,SPARQL) • Include links toother URIs, so thattheycandiscovermore (related) things • Open Data referstothe legal usageofdata * [Tim Berners-Lee 2007, http://www.w3.org/DesignIssues/LinkedData.html]

  12. Development ofLinked Open Data

  13. sameAs Linked Open Data by BBC

  14. Motivation • Value of data increases the more it is interlinked with other data • RDF to structure the data • HTTP URIs to publish • Semantic references such as owl:sameAs to semantically associate and link • LOD Benefits: • By following the links, humans can browse, search engines can crawl • Query expansion capabilities over distributed data

  15. Usage of the „Crowd Sourcing“
