NCDC Making Metadata Work For You FGDC / NOAA
What IS Metadata?
Data ‘reporting’ WHO created the data?
WHAT is the content of the data?
WHEN was it created?
WHERE is it geographically?
HOW was the data developed?

Which of these data and project management metadata applications are you most likely to use and why?
Are there additional metadata applications that would serve your organization?

Operational Content
To fully realize the operational value of metadata it is important to utilize standardized vocabularies and provide rich content.
The following content recommendations support:internal data accessproject monitoringISO transition geodata.gov participation
…see Handout ‘Metadata Quick Guide’

How Do I Create Metadata?
Steps to Success:
1. Understand the organization and content of the CSDGM
2. Learn to use the CSDGM Workbook (aka The Greenbook)
3. Select a metadata editor tool
4. Apply the CSDGM to your data
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
The CSDGM documents:
digital geospatial datadigital geospatial data
imagery digital land surveysGIS files geographic databases
MANY fields will not be applicable to your data
Your missionYour mission is to understand the standard well-enough to model it for your own use.
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
Standard is organized into seven primary sections
There are three ‘supporting’ sections that repeat within the primary sections:
citation• a standardized way to cite the data and source data
time period information• a standardized way to record dates
contacts• a standardized way to document contacts
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
1. Identification InformationGeneral bibliographic information including:
title, originator, data contact, status, date, time period of content, abstract, purpose, keywords, geographic location
2. Data Quality InformationLineage and data assessments
sources, process methods, accuracy, data processing contact
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
3. Spatial Data OrganizationData format:
vector, point, raster
4. Spatial Reference InformationCoordinate system parameters:
horizontal / vertical coordinate system, projection, datum
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
5. Entity and Attribute InformationDatabase design
entities, attributes, domains, description of data values
6. Distribution InformationHow to acquire the data
distribution contact, available formats, online distribution website, costs
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
7. Metadata Reference InformationGeneral information about the metadata record itself
metadata contact, metadata standard used, metadata creation date, metadata review date
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Overview
But that wasn’t enough for some people like Ted..
Extensions:added elements to the CSDGM
• Remote Sensing Extension
Profilescontent requirements for specific elements
may included added elements as well• Biological Profile
• Shoreline Profile
NCDC Making Metadata Work For You FGDC / NOAA
Mine the Metadata Exercise
Use your new understanding of the CSDGM to navigate through the sample metadata record and find answers to a set of questions.
NCDC Making Metadata Work For You FGDC / NOAA
CSDGM Workbook
AKA The Greenbook, it provides:background information about the development and purpose of the CSDGMexplanation of the organization of the CSDGMFAQs about specific elementssample values for specific elementsinstructions on creating Profiles and Extensionssample Metadataa glossary of terms
the CSDGM Workbook is your best metadata friend
NCDC Making Metadata Work For You FGDC / NOAA
Metadata Tools
How do I determine the best metadata tool?Does your organization provide a tool that meets specific data management objectives?Does your GIS software provide an internal metadata editor?Do you need a tool that supports one or more CSDGM Profiles or Extensions? Do you need to document data resource beyond those managed within your GIS? Do you need a tool that is easily distributed to partners? What features are most important to you?

What about legacy metadata?
NCDC Making Metadata Work For You FGDC / NOAA
Now….1. Continue creation using CSDGM vers.2 !!!
2. Use ISO-poised softwareESRI ArcCatalog
Intergraph / SMMS
MetaD, FGDC/Polytechnic University Catalunya
3. Add Topic Categories as theme keywords with ‘ISO 19115 Category’ as keyword thesaurus
4. Monitor FGDC website for news, materials, and training opportunities
How do I prepare?
NCDC Making Metadata Work For You FGDC / NOAA
Soon…1. Educate and inform your organization that a
migration, and assistance, is in the future
2. Develop a metadata conversion plan using crosswalks and conversion software
3. Adopt ‘CSDGM vers. 3.0’ when finalized
