GOS Goal
easier, faster and less expensive access to
geospatial data



Establish an online portal to geospatial data – with
an interactive index to geospatial data holdings at
the Federal and non-Federal levels
Develop standards and models to support the
exchange of framework datasets to facilitate web
services,
Promote partnerships among Federal, state, and
local agencies for planned geospatial data
collections.

Harvesting Metadata
Uploading Metadata (XML)
Enriching Metadata for GOS
Current Publication Options

Users may contribute metadata one of
three ways:
1.
2.
3.
Register their existing XML metadata
collection for harvesting into the GOS
metadata repository
Upload metadata as FGDC-XML to the
geodata.gov site
Enter FGDC metadata into a form at
geodata.gov and they are stored and indexed
there
Harvesting Metadata

An automated scheduled process for
collecting new and updated metadata from a
variety of metadata repositories.



Z39.50 metadata clearinghouse node
ArcIMS metadata service
Web Accessible Folder
Open Archive Initiative (OAI) metadata service
Harvesting Metadata
How does it work?



First retrieval- all metadata records with GOS
required content are retrieved
Previously harvested repository- only updated
metadata retrieved.
Validation



Requires GOS minimum metadata
Uses FGDC metatags for validation
Publishing

All successfully validated metadata is published in
geodata.gov.

Check version. New release implements Unique
ID.
Verify if unique ID has been implemented in
each metadata
Once harvested, subsequent harvests checks
update date for updated metadata.

Metadata published and searchable in geodata.gov
Insert ISO theme keyword in new metadata
Use GOS cross-walk table to translate your local
keyword(s) to ISO keyword. See GOS registration

Register their existing metadata collection to
be harvested into the GOS metadata
repository
Upload metadata as FGDC XML to the
geodata.gov site
Enter FGDC metadata into a form at

Upload XML Metadata
If you have access to a metadata editor such as
ArcCatalog but do not have a Z39.50 server or
ArcIMS Metadata Server you can upload a small
set of FGDC metadata to geodata.gov

Data Entry Form
Those without an
implemented metadata
tool and anticipate only a
few records to be
published to geodata.gov
may use the online entry
form to collect an
abbreviated FGDC
metadata for hosting at
geodata.gov

GeoData Partnership
Opportunities (Planned Data Acquisitions)
Federal agencies required to post data
acquisitions on geospatail-one-stop.gov to
encourage data partnership and fiscal
responsibility
