A Framework for Earth Science Search Interface Development Designing and Implementing S2S Eric Rozell, Tetherless World Constellation, RPI

Outline S2S Overview Motivations & Use Cases Research & Development Methodology Framework Architecture Prototype Implementation Results & Future Work

S2S Overview Supports reuse of user interface components (“widgets”) Uniform search interface for semantically-annotated web services Applies ontology to describe the application framework

S2S Overview

Motivations 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

Use Cases 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.

Research Methodology Fox et al., 2009

Prototype Implementation Technology: Data Resources:

Results Extensible Framework –Add web service standards –Add search and analysis widgets –Add data services Enables community development –Data managers –UI designers Uniform search interface –Customizable, reusable

Future Work Implement additional web service standards –e.g., SAWSDL, SPARQL services, OGC standards S2S as a discovery interface S2S as a federated search environment S2S evaluations (usability, extensibility) –VSTO Evaluation Metrics (McGuinness et al., 2007)
