Metadata @ CSC
Michael Moeller
Metadata Specialist
First things first
The What• Metadata is documentation that describes a data set
• It is written in accordance with the Federal Geographic Data
Committee’s (FGDC) Content Standard for Digital
Geospatial Metadata (CSDGM)
The Why• Mandated through Executive Order 12906
• It’s just good data management

Multiple organizationsproviding metadata
The HowMetadata is used for data discovery, assessment,
access, and use. The data discovery component is
accomplished via the FGDC Clearinghouse system.
We maintain one of the six gateways into the
clearinghouse system, and the CSC and NOS
nodes are housed here at the Center.
Writing Metadata @ CSC
The When• Prior to beginning project, project lead meets with metadata specialist to
discuss metadata needs and requirements for project.
• Schedule training as needed for internal and external staff.
During the life of the project• Project members meet with metadata specialist as needed to discuss metadata
creation. Ideally, metadata should be written throughout the life of the project, not just at
the end of the project.
• As metadata is completed, it should be submitted to metadata specialist in text format for
compliance review. Any errors present will be returned to project member for
correction. Metadata specialist will assist with corrections where required.

Existingprojects
• Project leads should assess status of metadata requirements for all current
projects. Is metadata currently being created? If not, why? What
issues need to be addressed to get metadata creation started?
Outside dataData brought in from outside sources should have metadata with it. If no
metadata exists, work with data provider to create appropriate metadata. In
some situations, Center staff may have to create metadata for outside data. If
this occurs, state clearly that the data did not have metadata associated with
it, and that metadata is being written by someone other than the data
creator/originator.
When to write
If your project incorporates other data that has metadata, you do not have to
write metadata again for that data. You only document what you do with the
data as it relates your project. Data used in your project is referenced in the
“Lineage” elements of Section 2 – Data Quality of the CSDGM.
Any possible problems with this concept?
Now Serving Metadata
How metadata is served up• Once all metadata is complete and approved and the project data is ready
to be served, a copy of all the metadata for the project will be posted to
the clearinghouse node.
• All project metadata should accompany each copy of the project data that
leaves the Center. This means that 2 copies of metadata may exist;
one copy on the node, and one copy with the data. This requires more
diligence on the part of project staff to make sure that any updates to
the metadata are sent for approval and posting on node.
• Hosting of metadata for project partners should only be done with
appropriate management approval.
• Metadata will remain on the node as long as the data is available. If a data
set is no longer being distributed, metadata specialist should be notified so
related metadata can be removed from the node and archived with the
data.
Events at large
Geospatial One-Stop (GOS)
• One of the E-gov initiatives
• Purpose of GOS is to make it easier, faster, and less
expensive for all levels of government and the public to
access geospatial information.
• GOS portal allows access to data “communities.” CSC is the
steward for the Ocean and Estuaries community, and
the Atmosphere and Climate community.
• Communities will offer opportunity to promote CSC and
partner products and projects within the Ocean and
Estuaries community.

GOS 2 – A work in progress
Events at large
• GOS harvests our metadata for inclusion into their system.
Part of the requirement for harvesting is the addition
of ISO topic keywords.
• Theme keywords in existing CSC metadata have been
mapped to ISO topic keywords, and each record on our
node now has these ISO keywords as part of the
record.
• Future metadata records written at CSC will need to
incorporate ISO topic keywords.

Metadata training available:
• Introduction to Metadata
• Metadata for Managers
• Metadata Train the Trainer
Metadata Training – Finding the Need
Project leads should assess the need for training within their
respective projects, considering both internal staff and any staff from
project partners, and work with Center metadata specialist to
secure appropriate training.
Training can be provided at the Center, or at partner locations.
Focus is on building capacity within our partner organizations,
working toward their self-sufficiency with respect to metadata.
Future plans
• The CSC metadata node will be undergoing a reorganization in
the near future. This will require an inventory of existing
metadata to ensure all metadata currently being served
accurately reflects data and products available through
CSC and partners.
