  2. What is Linked Open Data?
    • w3c Semantic Web Technology Stack
    • Web of atomized Data, not a web of documents
    • RDF; OWL ontologies; SPARQL queries; triple/quad/quint
    • httpRange14; content negotiation; CURIE
    • No restrictions on data use; free and easy license
    • Not of direct interest to most "real users"

  3. What is Linked Open Data?
    • Getting to the good stuff
    • Blue underlined text
    • Pulling in data from multiple sources, in an intelligent
    way, into a "document"
    • Understand and discover relationships
    • Open access for research, education, private study and
    other fair use

  25. Tinkerpop graph database stack
    • Simple "property graph" model
    • "JDBC for graph databases" [SNAC is using Neo4J for
    the graphDB]
    • XPath like "gremlin" for graph query
    • REST interfaces with "Rexster"
    • For me, this was 10 to 100 times easier than using RDF

  31. • Record view page has meta link to Summers style
    RDF for the page (via SPARQL query). -- content
    negotiation is not supported, but I think what we are
    doing is httpRange14 compliant
    • Also experimenting with italian RDF via xslt

  35. Future LOD plans for SNAC
    • Stable URIs between batches
    • More links to related sources such as dbpedia, IMDB,
    familysearch, id.loc.gov
    • Content negotiation (in SNAC 2 I'll have control over the front
    end apache, so this should be easy enough)
    • Visualizations useful and integrated (network and geospatial)
    • Integration with local systems (such as with the context
