Status Update

FGDC/ISO Metadata Standard HarmonizationUS ANSI L1 voted “Yes” for 19115 to proceed

to Draft International Standard (Only 1 nation voted NO – the UK) FGDC and USGS voted No

www.fgdc.gov/metadata/whatsnew/fgdciso.html

Slide 16

Profile Update FGDC/ISO Metadata Standard Profile Schedule

2 (or more) Profiles # 1 - To enable existing FGDC V2 records to be ISO compliant # 2 – A more “restrictive” profile

Fulfill deficiencies in FGDC CSDGM To meet lessons learned over last 6 years

January 2001 – One week workshop to begin Profile # 2 Development

Issue - “Profile” definition (“what one is”) in ISO is still undecided

Issue – Profile by Nation, Organization, Discipline, Data Type?

Slide 17

Category 2 – FGDC/ISO Metadata Conversion Software Conversionaward to RTSe, Inc. 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

Slide 19

Software Update Information

• Isite 2.07 release details

• RTSe GeoConnect announcement

• Blue Angel Gateway enhancements

• Island Edge (ICN) Search Client

Slide 20

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

Slide 21

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

Slide 22

Slide 23

SMMS for GeoMedia

Slide 24

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),

Slide 25

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

Slide 26

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)

Slide 27

Step 1: Select Nodes based on ISO 19115 Categories

Slide 28

Step 2: Define Geographic Area of Interest

Slide 29

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

Slide 30

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

Slide 31

Step 5: Search and request results

Slide 32

Step 6: See titles of results from a given server

Slide 33

Step 7: Display and evaluate the metadata

Slide 34

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! http://clearinghouse1.fgdc.gov/servlet/FGDCWizard

Slide 35

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

Slide 36

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

Slide 37

List of adapted ISO 19115 Categories

• Agriculture and Farming: 001

• Atmospheric and Climatic Data: 004

• Biologic and Ecologic Information: 002

Items 200-203 are FGDC subdivisions of existing Categories

Slide 38

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:

Synonyms=on• Restart zserver

Slide 39

ICN Search Client• Web interface to GEO servers

– Access to distributed, regional GEO servers– Resource location via online FGDC registry– Distributed search to selected servers

• Uses new Wizard-style interface– Easy-to-use– Customizable by administrator

• Open source, pure Java software– Installs as web servlet using Jserv or Jrun– Alternative to Isite’s zgate/zcon

Slide 40

ICN Client – Steps 1 and 2

Slide 41

ICN Client – Steps 3 and 4

Slide 42

ICN Search Client - Status

• Currently in active development but not yet documented for simple installation
