  1. Global Change Information System: Information Model and Semantic Application Prototypes (GCIS-IMSAP) Status 01/08/2013 Stephan Zednik1, Curt Tilmes2, Peter Fox1, Justin Goldstein3, Marshall Ma1, Jin Zheng1 1 – Tetherless World Constellation, RPI 2 – NASA Goddard, USGCRP 3 – UCAR, USGCRP

  2. GCIS Ontology

  3. GCIS Ontology (cont.)

  4. Key Message & Traceable Account

  5. Key Message vs. “General” Message (early draft)

  6. Prototype Use Case (UC-1)

  7. Prototype 1 • Initial Implementation of UC-1 • Exposes Linked Data API • RESTful • RDF/XML, TTL, HTML, JSON supported • Hosted at TWC / RPI • currently placeholder data • http://globalchange.tw.rpi.edu/elda/gcis/report/nca2009.html • Implemented using Epimorphics Linked Data API (ELDA) • http://code.google.com/p/linked-data-api/(spec) • https://code.google.com/p/elda/ (implementation)

  8. Linked Data API Architecture

  9. Prototype Screenshot

  10. Next Steps • Ontology • Finalize Traceable Accounts • Explore Key Message vs. General Message • Instance population with real data • Develop more use cases • Refinement of existing prototype • Search • Faceted browser • CLEAN to GCMD vocabulary mapping

  11. Prototype Use Case (UC-2)

  12. Free-text Search by Keyword (ELDA)

  13. Faceted Browser (S2S) Data type Facet Vocabulary Facet

  14. Climate Literacy & Energy Awareness Network (CLEAN) • http://cleanet.org/index.html • The CLEAN project, a part of the National Science Digital Library, provides a reviewed collection of resources coupled with the tools to enable an online community to share and discuss teaching about climate and energy science. • Science Vocabularies for middleschool to undergraduate students • Vocabularies hosted at http://serc.carleton.edu/admin/manage/view_vocab.php?vocab_id=161

  15. CLEAN Vocabulary

  16. CLEAN Vocabulary (cont.)

  17. CLEAN Vocabulary (cont.)

  18. GCMD CLEAN Mapping • Provide CLEAN as an alternative (and non-specialist) vocabulary by which terms can be searched browsed • SKOS Encoding of CLEAN Vocabulary • Map GCMD SKOS to CLEAN SKOS • GCIS data registered with GCMD Keywords • Search & Browse available by GCMD Keyword or CLEAN terms
