  • Make researchers aware of the importance of sharing data.Sharing data becomes even more a requirement than a wish.Support publications
  • Role of the library is to support researchers managing and storing data
  • N = amount of participants
  • Virtualdatastreams: services (image resize, file conversion)
  • Updates from Fedora are sent by JMSThe rest/soap interface is not used
  • Request based: user needs to create a request. Works like a shopping cart. The request needs to be approved. Uploads need to be reviewed also.
  • Solr 1.3
  • Transcript

    • 4. Project Drivers
      UvALibrary: make researchers aware of the importance of sharing data
      Making research data publically available becomes more and more a requirement than a wish
      Publishing: Support publications by disseminate the underlying research data
      Teaching: have students work with actual research data

    • 6. Project history: testweeklab
      ‘Testweeklab’ project (2008)
      Work with 40 years of privacy sensitive research data
      Strong security requirements
      Only metadata (publically) accessible
      Complicated access procedure for accessing the actual data
      Very specific metadata schema, search and browse requirements
      Very specific fields (year, N, type of test, scale)
      Build as Sakai tool for connecting to a Fedora repository
