1 EPA GIS Workgroup - Metadata National Geospatial Overview: Metadata EPA GIS Workgroup Meeting Fall 2004 Las Vegas, NV

2 EPA GIS Workgroup - Metadata FGDC and GOS Metadata Compliant metadata, richly informative Metadata Repositories GOS partnership

3 EPA GIS Workgroup - Metadata Complaint Metadata More than CSDGM Sections 1 and 7 Tools to help –CSDGM Graphic Representation version2/http://biology.usgs.gov/fgdc.metadata/ version2/ –Metadata Parser aka “MP” /tools/doc/mp.htmlhttp://geology.usgs.gov/tools/metadata /tools/doc/mp.html Web, batch, and desktop apps available Checks syntax/format not content

4 EPA GIS Workgroup - Metadata Richly informative metadata Metadata Quick Guide

5 EPA GIS Workgroup - Metadata Metadata Repositories Z39.50 –Centralized National Park Service –Centralized with program/agency identity –Distributed ArcIMS Metadata Service Web Accessible Folders (WAF) OAI Initiative (library) The Urban Environment Environmental Monitoring and Assessment Program EnviroFacts EPA Metadata Sites Estuaries Data Group

6 EPA GIS Workgroup - Metadata Register – Publish –Publisher –Geographic datasets –Images –Geoservices –Spatial solutions –Reference material –Events and activities –Geodata Partnership Opportunities –Schedule NSDI node –Metadata harvesting GOS Partnership

7 EPA GIS Workgroup - Metadata GOS Metadata Harvest How to contribute metadata: – Register existing metadata collection for harvesting, specify frequency and time. ArcIMS Server, Isite/ Z39.50, WAF or OAI – Upload metadata as CSDGM XML to the geodata.gov site – Enter metadata into a form at geodata.gov where it will be stored and indexed

8 EPA GIS Workgroup - Metadata Enabling Harvesting Register Harvest Site X

9 EPA GIS Workgroup - Metadata Enabling Harvesting Keyword Crosswalk

10 EPA GIS Workgroup - Metadata Metadata Harvest A scheduled automated process for collecting new and updated metadata from a variety of metadata repositories First retrieval- all metadata validated. Those containing GOS required content posted to geodata.gov Previously harvested- only updated metadata retrieved Validation –Requires GOS minimum metadata –Uses FGDC metatags for validation

11 EPA GIS Workgroup - Metadata GOS Required Metadata Content Originator Metadata Date Title Abstract Purpose Time period Progress Maintenance Bounding Box Keywords Information Derived from Registration*: Information Derived from Registration*: Contact Person or Organization Contact Person or Organization Address type, Address Address type, Address Phone number *When using online metadata form

12 EPA GIS Workgroup - Metadata GOS Metadata Validation- Metadata Parser (MP) Error reports forwarded to agency –“Errors” to be remedied –“Warnings” acceptable Metadata with errors are not posted to geodata.gov –Once errors are corrected, schedule for harvest –Common errors: Currentness Reference- null (ground condition, publication date, ”free text”) date format- YYYYMMDD (YYYY minimum)

13 EPA GIS Workgroup - Metadata Z39.50/Isite Repository requirements Isite Check for new release, new release implements unique ID –Document ID Verify if unique ID has been implemented in each metadata

14 EPA GIS Workgroup - Metadata Z39.50 / Isite Requirements Z39.50 – Verify if unique ID has been implemented in each metadata Isite – Check for new release, new release implements unique ID

15 EPA GIS Workgroup - Metadata Registering IMS or WMS Using agency metadata tool and repository: –Create metadata describing service, enter address in “Online Linkage” and post to agency clearinghouse On geodata.gov –Login –Go to publish a new record –Enter map service address

16 EPA GIS Workgroup - Metadata Contacts: Metadata- Clearinghouse/Portal –Doug Nebert
