  1. Semantic Data lives everywhere on the Web

  2. In a perfect world we would have... Download Semantic Data here

  3. The Web is a far from perfect world • Web presentation techniques are great at making data look nice but are also great at hiding or destroying the semantics all together • Rich data mired in HTML tables • XML and RDF turned into human-only readable data by style sheets and other transforms • Links to Semantic data are hidden in non-visible portions of the page • A Web page hiding rich Semantic data can be a tough nut to crack

  4. The Non-semantic shell of Semantic Data

  5. “Semantic Web Through the Eyes of a Parrot” Where is the nice tasty Semantic Data?

  6. The Nala Semantic Data Collection Plugin • Mozilla Firefox plugin client • OpenAnzo.org - RDF Database and Semantic Web application Server • Breaks through the non-Semantic shell around Semantic data in Web pages • Collects, stores and indexes Semantic data on the client and in a central database • Allows collaboration, rich query, and discovery of new relationships between objects from different Web pages

  7. A first look at Nala

  8. Semantic Web Technology isn't Magic • The Semantic Web • Unattainable, hollistic world of connected Semantic data • Organizations and their IT departments abandon 10+ years of infrastructure and database investment • Global agreement on ontologies • Software agents can crawl and make perfect sense of the world with little human guidance • everyone head for the hills! • Semantic Web Technologies • Powerful, concrete tools that can help realize many of the goals of The Semantic Web in particular situations, systems, and applications • Driven by adoption of important technology standards (HTTP, RDF, SPARQL, OWL, LSID)‏ • Do not require universal agreement and adoption of domain standards (ontologies, vocabularies, schemas)‏ • Enable organizations to captilize on infrastructure and data investments by exposing existing data as Semantic data on the Web

  9. Semantic Web Technology in Nala • Semantic Web Technology • Resource Description Framework (RDF)‏ • Named graphs • SPARQL – Query language and protocol for RDF • LSID Resolution • Other Technology • HTTP, AJAX, REST, Atom Publishing Protocol • Screen scraping • Text Indexing 'The Machine Readable Web' - Lee Feigenbaum and Elias Torres Part 1 - http://www.ibm.com/developerworks/library/wa-hmach1/ Part 2 - http://www.ibm.com/developerworks/library/wa-hmach2/

  10. A more involved scenario • Two different sources have information about the same biological concept. • Bioguid ( Rod Page)‏ • HTTP uri, proprietary RDF, some standard predicates • Herbimi ( Kevin Richards)‏ • LSID resolution • How can we • Crack through the different non-Semantic shells? • View this data merged in the same place? • Map key touch points where the ontologies intersect or relate? • Export the merged data for use in our other applications?

  11. The state of Nala • Available in TDWG lsid source control • https://lsids.svn.sourceforge.net/svnroot/lsids/trunk/demo/org.gbif.nala • Firefox Installer available soon • Public server installed • tdwgbox.tdwg.org • Future work • Use cases? • Additional development? • Domain-specific clients

  12. openanzo.org • Open and inclusive community of Semantic Web Technology adopters and engineers • Pure open source development community • Flagship project: Anzo RDF Database and Semantic Web Application Server • Based on IBM Semantic Layered Research Platform project • Founded and supported by new Boston, MA-based venture Cambridge Semantics Inc. • We are looking for contributors, testers, adopters and critics • If you are building (Semantic (Web) applications), give us a try • Documentation, releases, support are coming soon

  13. Cracking the shell • By adopting particular Semantic Web technologies as a community, we can release the potential wealth of knowledge locked in the data we have siloed in databases and Web pages.
