The document discusses the semantic web and its potential uses for liberal arts campuses. It provides an overview of semantic web technologies like RDF, OWL, and SPARQL. Examples are given of how semantic web tools could be used for campus projects, pedagogy, and research by exposing metadata and linking data. Challenges mentioned include complexity, lack of visible applications, and the ecological growth needed for widespread adoption.

- 17. Campus projects Enterprise or medium-scale architecture strategies repository (example: http://dspace.nitle.org/ ) general campus-housed documentation revise metadata strategy and/or run local app Rely on growing number of helper apps (i.e., Triplify, GRDDL, etc.)
- 18. Campus projects Why do such a thing? Campus research and connections Outreach Open content - connect with some academic projects, like OAI "make your information more programmable" (Reuters, Tim O’Reilly interview, February 2008, http://radar.oreilly.com/archives/2008/02/reuters-ceo-sees-semantic-web.html )
- 19. Campus projects Example: Vitro (Cornell, http://vivo.cornell.edu ) -across departments, admin. units
- 20. Campus projects Ontology editor available: http://vitro.mannlib.cornell.edu/ Needed: Java, Apache Tomcat and Ant, MySQL, Subversion Howto: create an ontology, then populate https://confluence.cornell.edu/display/VITROUSERS/Home

- 22. Pedagogies and research How: use preceding tools Why? information literacy: better, smarter search information aggregation, or "knowledge construction" (Jason Ohler) collaborative work, finding and facilitation computer science class projects
- 23. Pedagogies and research CS: create semantic tools Example: Welkin, from MIT’s SIMILE http://simile.mit.edu/welkin/
- 24. Limitations too geeky, not visible perceived expense no killer app complexity and scale of overall semantic enterprise ecological growth means natural selection
- 25. What to do with it? Your turn.
- 26. What next? What do you see? More tools More RDF-readable data exposed New functions RDFa->HTML5? Applying SKOS (Simple Knowledge Organization System) to references
