Key Topics
- ESRI GIS portal toolkit -> Geoportal Server ( Christine White (ESRI))
- Highly configurable
- Built on existing OSS platforms
- Active development
- NODC use of Geoportal for Integration/Interoperation, John Relph, NODC, Ken Casey, NODC, Li Yuanji, NODC
- Archival work - human and machine interfaces
- Target access to archives through various software services
- Need for service integration and organization
- Geoportal fills this need
- Machine-to-machine communication via REST URL
- Applications can construct individual URLs to pull targeted data
- Metadata selections, but custom coding often needed for unique datasets
- This lends itself to an agile archive which can conform to many different data/metadata requests
- Dynamic, metadata created Web Accessible Folders (WAFs)
- Brief Access Records merged with FGDC XML generates live archive WAF
- Applications can construct individual URLs to pull targeted data
- Archival work - human and machine interfaces
- NODC Collections WAF
- Collection level records, with HTML for Google harvesting
- Data.gov/Geospatial One-Stop WAFs
- Immediately downloadable WAF only
- NODC Geoportal Server Usability Test for first-time users
- Most use was scientific research
- Many different countries
- Spatial search had highest difficulty, free text and web interface tasks were also problematic
- Indicated that the map locator needs work, as well as text search, default syntax, and ontology services were needed
- Additional data visualization needed
- Move for Geoportal to use ISO19115-2 metadata
- NGDC use of Geoportal David Neufeld (NGDC)
- Mixed content, WAF centric
- Common Property Meanings to create shared concepts
- Simplifies search modifications, custom links to data
- Common Property Meanings to create shared concepts
- Improving metadata content
- Must work with data providers
- Metadata report card, based on metadata conventions
- Federated searches
- Mixed content, WAF centric
- Collaborations
- Information sharing
- GEO-IDE Wiki
- Locator services
- Google code shared repository possible
- EPA use of Geoportal David Parrish (EPA)
- Environmental Dataset Gatewaty (EDG)
- v 1.0 of Geoportal customized for EPA needs

- Selection of data by region, type, owner
- Code for searches available to be imbedded in third party webpages
- Separation between public and private datasets
- Automation of data.gov records/inventory/formatting
- Metrics for data requests, world map of requests by country, metadata
- Clip N Ship
- Enhanced metrics, web services, web services and metadata
