Server and Gateway Status 243 servers, 214 active Six domestic Gateways but working on supporting other international gateways Support staff will continue to test all servers for availability, spatial, field, and text search
Gateway Software Blue Angel MetaStar Gateway 3.5.2 in use. Blue Angel is under contract to update the basic and Wizard interfaces ICN distributed search client still being tested and will have a similar Wizard interface for search (intended to replace the zcon/zgate capabilities of Isite)
Server Software Status Isite 2.07i in general release everywhere SMMS 3oh! GeoConnect Servers awaiting an imminent upgrade to make them searchable through Clearinghouse Gateways Compusult prototyping ISO metadata in their database/Z39.50 server solution
Recent Activity - Isite Scoring bug fixed for Boolean queries and virtual databases Improved XML for selected doctypes using zsearch/zpresent Spontaneous (?), occasional crash of NT zserver under investigation Any site running Isite 2.07 for NT that crashes is encouraged to send the error file from “Dr Watson” to firstname.lastname@example.org
Coming Soon - Isearch2 Major “roadblock” bug now fixed In limited beta test now Remote indexing - by URL Development activities –Doctype modification to support crawler –Crawler testing –How to handle element sets with crawler?
Metadata Software The MetaLite software is being re- engineered at FGDC by a visiting programmer from South Africa –supports ISO 19115 Core+ –is multi-lingual (extensible) –uses a tree and tab interface –imports and exports XML –planned for beta release late March
ISO Metadata Status Implementers are experimenting with the ISO metadata as XML in many settings – let’s share our work! Author is receiving editorial comments from nations and will combine them at the upcoming ISO TC 211 meeting March 9 th Metadata (ISO 19115) is expected to be approved as a Draft International Standard
FGDC to ISO Metadata RTSe has a contract with FGDC to develop a transformation program and style sheet to convert FGDC metadata in XML format to ISO metadata in XML format This will facilitate translation of metadata on- the-fly or for batch conversion of content Expect initial deliverable by April, final deliverable by July.
Frequently Asked Questions FAQ system is under development to answer common question about Clearinghouse and supporting software Could be used for other related activities Available temporarily at: http://edcnts9.cr.usgs.gov/fgdcfaq/default.asp http://edcnts9.cr.usgs.gov/fgdcfaq/default.asp
Search Wizard Overview 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
Step 1: Select Nodes based on ISO 19115 Categories
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 http://edcw2ks15.cr.usgs.gov/servlet/FGDCWizard
Search Wizard Feedback Email request sent yesterday to solicit comment from the user communityon what features you like, dislike, don't understand, or wish were there –What’s missing from spatial/placename search? –How can the Extent capability be improved? –How could topic selection be done better? –How can the “field” query page be improved? –How do you like the layout of results?

Activity Reports NASA: the metadata display from IDN/GCMD now appears properly through the clearinghouse gateway - as an FGDC- formatted record. Greater Yellowstone Area Data Clearinghouse is moving to become the Yellowstone-to-Yukon node hosted by USGS. Mark as inactive for a few months. ESRI Geography Network now searchable as a Clearinghouse Node Arctic GIS Workshop (next slide)
Arctic GIS Workshop Arctic Research Consortium of the United State (ARCUS) http://www.arcus.org/gis/index.html and National Science Foundation (NSF) Which Arctic science issues would benefit from improved internet-base GIS capability? What strategies could be used to implement enhanced GIS capability for the Arctic? What are the anticipated impacts in terms of research and societal benefits? Preliminary Recommendations A shared vision of an Arctic Spatial Data Infrastructure (ASDI) as an international cooperative initially based on nodes at USGS Alaska, UNEP Grid-Arendal, National Snow and Ice Data Center (NSIDC) and University of Alaska, Fairbanks
Upcoming Events Next Clearinghouse WG Telecon May 16 th, 2001 Considering a North American SDI implementers’ workshop for the summer, possibly co-sponsored by CEONet, FGDC, and NBII, etc.
