recent isearch enhancements
Recent Isearch Enhancements
  • New command-line programs:
    • zsearch
      • same command syntax as Isearch
      • returns result list in XML
    • Iget
      • retrieve document by database name & docid
    • zpresent
      • like Iget, but attempts to wrap result in XML
      • only reliable for NASA/EOS Guide docs now
coming soon isearch2
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
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
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’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
Search Wizard Summary
  • Remedies some ergonomic issues identified in usability study
  • Improves search scalability by targeting search to likely Nodes
  • Provides a model that can be adapted for different user communities
  • Is a work-in-progress – input wanted!

planned gateway enhancements
Planned Gateway Enhancements
  • Wording changes, obvious ‘Help’ links
  • Results to be shown on an index map
  • Summary records will be displayed with a timebar and map extent
  • Use of synonym expansion at servers will permit search for records based on ISO 19115 Categories
using topical search
Using Topical Search
  • Registry has best-guess ISO classifications for your server. Please review and revise the Categories appropriate to your metadata collection
  • Category search is limited to the Registry, but you can train your server to support ISO Categories in Isite through use of synonyms in sapi.ini
  • Consider expecting this functionality in 2001
