  1. Context and Prosopography: Putting the 'Archives' Into LOD-LAM Corey A Harper SAA 2012 - MDOR 2012-08-08

  3. Linked Open Data • Use URIs as names for things • Use HTTP URIs so that people can look up those names. • When someone looks up a URI, provide useful information. • Include links to other URIs. so that they can discover more things. http://www.w3.org/DesignIssues/LinkedData.html Harper - SAA - Metadata and Digital Object Roundtable

  4. Linked Data • Metadata as a Graph • Typed “things”, named by URIs • The relationships between those things, also built on URIs • Ease of integration *across* data sources – “merging graphs” Harper - SAA - Metadata and Digital Object Roundtable

  5. Examples Harper - SAA - Metadata and Digital Object Roundtable

  6. Remodel to link Harper - SAA - Metadata and Digital Object Roundtable

  7. And Link to Other Descriptions Harper - SAA - Metadata and Digital Object Roundtable

  8. Semantic Web Terminology • Resource: Any “thing” • Class: Abstraction of a type of thing • Individual: An instance of a class • Property: An attribute of an individual • Statement/Triple: • A Resource (subject) • A Property (predicate / verb) • A Value (object) - Nodes • Graph: Visual Representation of statements • Ontology: A domain specific collection of classes and properties Harper - SAA - Metadata and Digital Object Roundtable

  9. Semantic Web Terminology • Nodes: The Subjects and Objects in a Graph • Arcs: The Predicates in a Graph • Domains and Ranges: Constraints on Nodes • Domain: What things can be subjects • Range: What things (or strings) can be objects • Literals: Values as strings rather than things • Named Graphs: Graphs with URIs treated as nodes. Harper - SAA - Metadata and Digital Object Roundtable

  10. Open & Closed World Assumptions • Closed World - Metadata patterns known, semantics implicit • Open World - Continual integration of heterogeneous metadata • Requires Self-Describing Data • Linked Data Principles come in big here http://www.w3.org/2001/tag/doc/selfDescribingDocuments Harper - SAA - Metadata and Digital Object Roundtable

  11. Library Systems are *Closed* World! http://www.flickr.com/photos/tomgehrke/6950344619/ Harper - SAA - Metadata and Digital Object Roundtable

  12. Most Metadata *systems* are closed world • Libraries, Archives, Museums • Publisher provided data • Other scholarly systems: • Even Open Access ones (OA != OW) • Search Interfaces (even Google!) • You manage what you have, and generally manage a closed set of metadata Harper - SAA - Metadata and Digital Object Roundtable

  13. Social Networks of Archival Context Image From: http://inkdroid.org/journal/2010/08/12/archival-context-on-the-web/ Harper - SAA - Metadata and Digital Object Roundtable

  16. So back to my title… Prosopography The study of an aggregate group based on systematic biographical study of individuals http://en.wikipedia.org/wiki/Prosopography http://prosopography.modhist.ox.ac.uk/course_syllabuses.htm Harper - SAA - Metadata and Digital Object Roundtable

  17. Context Narrative Story telling The archive’s story, but also… Harper - SAA - Metadata and Digital Object Roundtable

  18. Users’ stories Adding context through recombinant metadata Harper - SAA - Metadata and Digital Object Roundtable

  19. Distributed information ecosystem • Linking Data • Focus on identification over description • Create navigable, browsable information landscapes • Relationships between resources weave context & enrich user experiences Harper - SAA - Metadata and Digital Object Roundtable
