  • Why RDF?People change their minds; easy to change things with RDF.
  • - Finer grain control oversolr documents since you decide which elements are indexed whereas OM indexes all elements and interstitial nodes- well-crafted triples are more portable- Coding/parsing RDF is trivial compared to coding/parsing XML
  • RDF in Hydra Summit Overview

    1. 1. RDF IN HYDRA SUMMIT OVERVIEW Brought to you by Karen Estlund Head, Digital Scholarship Center University of Oregon kestlund@uoregon.edu
    2. 2. Participants • Declan Fleming, UCSD • Matt Critchlow, UCSD • Tom Cramer, Stanford • Lynn McRae, Stanford • Chris Beer, Stanford • Mark Bussey, DCE • Mike Giarlo, Penn State • Tom Johnson, Oregon State • Karen Estlund, University of Oregon • Jon Stroop, Princeton University • Jeremy Friesen, Notre Dame • James Van Mil, University of Cincinnati
    3. 3. Objectives 1. Compare Practices and Approaches 2. Examine the implications / opportunities: • Fedora 4 • Hydra
    4. 4. Discussion Highlights
    5. 5. RDF is not synonymous with Linked Data. RDF is a mechanism to leverage Linked Data.
    6. 6. Convoluted Terms • Data Model • Ontology • Application Profile • Data Dictionary
    7. 7. RDF in Hydra In Practice • Qualified Dublin Core • GeoNames • MODS • LC Subjects • Heterogeneous • Dublin Core • MODS • VRA Core • DarwinCore • DataCite • Etc… • Lexvo Languages • LC Genres • AAT • Etc..

    12. 12. Why RDF? • Granularity of description • Flexibility of schema • Extensibility of schema • Re-usability and utilization of Linked Data • Self-describing and can carry meaning It’s not just machine readable; it’s machine actionable!
