title: UROBE: A PROTOTYPE FOR WIKI PRESERVATION
creators: Niko Popitsch Robert Mosser Wolfgang Philipp
abstract: More and more information that is considered for digital
  long-term preservation is generated by Web 2.0 applications
  like wikis, blogs or social networking tools. However,
  there is little support for the preservation of these data today.
  Currently they are preserved like regular Web sites
  without taking the flexible, lightweight and mostly graphbased
  data models of the underlying Web 2.0 applications
  into consideration. By this, valuable information about the
  relations within these data and about links to other data is
  lost. Furthermore, information about the internal structure
  of the data, e.g., expressed by wiki markup languages is
  not preserved entirely.
  We argue that this currently neglected information is
  of high value in a long-term preservation strategy of Web
  2.0 data and describe our approach for the preservation
  of wiki contents that is based on Semantic Web technologies.
  In particular we describe the distributed architecture
  of our wiki preservation prototype (Urobe) which implements
  a migration strategy for wiki contents and is based
  on Semantic Web and Linked Data principles. Further,
  we present a first vocabulary for the description of wiki
  core elements derived from a combination of established
  vocabularies/standards from the Semantic Web and digital
  preservation domains, namely Dublin Core, SIOC, VoiD
  and PREMIS.
