NAAC Slides on SNAC prototype access system

slides from my presentation at NARA

Transcript

1. Historic Social Networks Prototype access system
2. Outline • User Persona • Search and Display • Linked Data / RDF • Network graph visualization • Future Plans
3. Meet the target users • Randy: Graduate student working on a PhD that involves biographies and the study of diplomatic families and networks. Sometimes he comes to the site looking for information on specific people; other times he is looking for information on a specific subject or event. He also TAs an undergraduate history class and sometimes has to help students find topics for papers. • Connie: Works at an institution that contributed records to the project. Is going to be asking themselves how this site would be useful to their users. Wants to understand how their records were used and what the added value is. • Quincy: Library School Student working to QA record matching. • Adele: Person doing authority work during collection processing. • Lenny: Lenny likes linked data, and wants to be able to mine the links that have been established programatically. Personas are fictional characters created to represent the different user types within a targeted demographic, attitude and/or behavior set that might use a site, brand or product in a similar way. http://en.wikipedia.org/wiki/Persona_(marketing)
4. Outline • User Persona • Search and Display • Linked Data / RDF • Network graph visualization • Future Plans
14. Advanced limits match EAC sections
33. Outline • User Persona • Search and Display • Linked Data / RDF • Network graph visualization • Future Plans
34. RDFa owl:sameAs
35. HTML 5 microdata in chron list
36. Thanks Ed Summers! RDF of the social graph
39. • 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
40. http://templates.xdams.net/IBC/ontology/eac-cpf.rdf Silvia Mazzini regesta.exe srl
42. &mode=xml2owl [experimental]
44. Outline • User Persona • Search and Display • Linked Data / RDF • Network graph visualization • Context widget (needs new name) • Future Plans
45. 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
55. Outline • User Persona • Search and Display • Linked Data / RDF • Network graph visualization • Future Plans
56. Future Plans • Conduct assessment activities involving members of target audiences to establish mental model of users for design work • Scale interface to millions of names • Visualizations useful and integrated (network and geospatial) • Stable URLs between batches for linked data • Social and personalization features (gateway to crowdsourcing) • Integration with local systems (such as with the context widget)
