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.

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”

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

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.

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

Library Systems are *Closed* World!

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

So back to my title…
Prosopography
The study of an aggregate group based on systematic biographical study of
individuals

Context
Narrative
Story telling
The archive’s story, but also…

Users’ stories
Adding context through recombinant metadata
2012-08-08 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
