EPA GIS Workgroup - MetadataGOS 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

EPA GIS Workgroup - MetadataMetadata 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

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)

EPA GIS Workgroup - MetadataRegistering 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
