      • returns result list in XML

    • Iget

      • retrieve document by database name & docid

      • like Iget, but attempts to wrap result in XML

      • only reliable for NASA/EOS Guide docs now

Coming soon isearch2 l.jpg
Coming Soon - Isearch2

  • Different index architecture to provide:

    • Improved search performance

    • No reliance on source documents

    • Remote indexing - by URL

    • Regular expressions?

      • Compile-time only, major impact on index size

    • In early beta test now, with frequent releases to follow

Blue angel gateway l.jpg
Blue Angel Gateway

  • Version 3.5.1 installed at FGDC, AGDC, NRCS, NOAA-CSC (pending at EDC and ESRI)

  • International Gateways planned (2001): AUSLIG (Australia), NGDF (UK), IGAD (Kenya), INEGI (Mexico), Honduras, GSI (Japan, maybe),

Gateways cont d l.jpg
Gateways, cont’d

  • Gateway 3.5.1 has ‘no-map’ and java-based map search interfaces

  • Update script synchronizes all active, registered servers into the search form as eligible targets – should yield same form style/content on all Gateways

Gateways cont d26 l.jpg
Gateways, cont’d

  • Search wizard being implemented in two forms to help select servers based on GSDI Registry metadata. Uses:

    • Geographic area selection

    • Scope or Extent of collections

    • Thematic classification as per ISO 19115 Categories tags (next version: Dec)

Search wizard summary l.jpg
Search Wizard Summary re-used
