      • FGDC and USGS voted No

Profile Update

  • FGDC/ISO Metadata Standard Profile Schedule

    • 2 (or more) Profiles

      • # 1 - To enable existing FGDC V2 records to be ISO compliant

    • Brainstorming telecon – November 2000

    • Imported Metadata (triplet) must be well-formed (ie mp output) – will not attempt to “fix” existing FGDC metadata

    • Discussion - 3 “execution” options

      • ie DOS Command Prompt

      • Windows-based application

      • Web-based application

    • “Black box” look/feel

Software Update Information

  • Isite 2.07 release details

  • RTSe GeoConnect announcement

  • Blue Angel Gateway enhancements

  • Island Edge (ICN) Search Client

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

  • 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

SMMS for GeoMedia

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

  • 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)

Step 1: Select Nodes based on ISO 19115 Categories

Step 2: Define Geographic Area of Interest

Step 3: Review, select/deselect from ‘found’ servers

Step 4: Compose query of selected servers, spatial extent is re-used

Step 5: Search and request results

Step 6: See titles of results from a given server

Step 7: Display and evaluate the metadata

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

  • 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

  • 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

Supporting Synonyms in Isite

  • Reindex with Iindex option:

    -syn /path/filename

    filename contains many lines in the form:

    Term alternate1 alternate2 …

    e.g. 001 agriculture farm farms farming

  • In sapi.ini [server] block add the line:


  • Restart zserver

ICN Search Client

  • Web interface to GEO servers

    • Access to distributed, regional GEO servers

    • Resource location via online FGDC registry
