2. Outline What is being done? Why are you doing it? How will you do it? What do you hope to learn? Why is it important? Status

3. What is being done? Design of S2S Framework Implementation of S2S Framework Evaluation of S2S Framework

4. What is being done? Supports reuse of user interface components (“widgets”) Automatically generates search interfaces for semantically-annotated web services Applies RDF and OWL to describe the application framework

5. What is being done? Supports reuse of user interface components (“widgets”) –How? Automatically generates search interfaces for semantically-annotated web services Applies RDF and OWL to describe the application framework

6. What is being done? Supports reuse of user interface components (“widgets”) –How? Automatically generates search interfaces for semantically-annotated web services –To what benefit? Applies RDF and OWL to describe the application framework

7. What is being done? Supports reuse of user interface components (“widgets”) –How? Automatically generates search interfaces for semantically-annotated web services –To what benefit? Applies RDF and OWL to describe the application framework –Why?

8. Why are you doing it? Incentivize compliance to web service standards Assist data management communities in search interface development Lay foundations for federated search and data integration Enable community development

9. Why are you doing it? Use Case NameOceanography Dept. CollaboratorsDescription Southern Mariana Trough Cruise Preparation Biology (Larval Ecology) Stace Beaulieu, Andrew Maffei, Peter Fox A biologist is preparing an upcoming cruise to study larval ecology at the Southern Mariana Trough. She’s interested in CTD data, ocean currents, biogeographic data, and hydrothermal vent information. Ideally, this data can be discovered from a single online resource. Deployment Data & Metadata Discovery Geology & Geophysics Maurice Tivey, Andrew Maffei Find deployments (e.g., cruises, dives, lowerings) that visited the Vema Fracture Zone and associated metadata including bathymetry instruments, underway data, and occurrences of dredging. Visual Ocean Profile Finder Physical Oceanography Ruth Curry, Andrew Maffei Determine ocean profile data availability through a visual (e.g., map) interface, allowing restriction of results based on geographic line or area and measured parameters. Integrating Metagenomics and Ocean Properties Chemical Oceanography Mak Saito, Andrew Maffei Integrate web resources publishing metagenomic data and chemical ocean properties to facilitate the study biological effects on ocean chemistry.

10. Why are you doing it? Research Question –What can semantics enable in dynamic web application framework that is not possible (or difficult) with a traditional object-oriented approach?

11. How will you do it? Fox et al., 2009

12. How Will You Do It? ExView (Maffei et al., 2007) and 4DGeoBrowser (Lerner and Maffei, 2001)

13. How Will You Do It? VSTO Evaluation (McGuinness et al., 2007) –Quantitative Metrics –Qualitative Metrics

14. What do I hope to learn? Answer to research question –Does S2S provide any features that would be difficult/impossible to implement using an object-oriented approach? Does S2S incentivize the use of web service standards, or alleviate search interface development burden of data managers? In what ways can S2S user interface components be reused?

15. Why is it important? Incentivize compliance to web service standards Assist data management communities in search interface development Lay foundations for federated search and data integration Enable community development

16. Status Design of S2S Framework –(Done) Implementation of S2S Framework –(Partially Complete) Evaluation of S2S Framework –(Not Started)
