Metadata Workshop
Frank Roberts, Coeur d’Alene Tribe GIS
Bruce Godfrey, U of I, Inside Idaho Project
(Funded by FGDC)
Metadata Workshop Agenda 1) Description of the FGDC metadata standard. (Frank) 2) What does a GIS person really have to collect to be compliant?--Structure and
components of FGDC CSDGM-compliant metadata. (Frank) 3) Why we create metadata and how it is useful--FGDC National Geospatial Data
Clearinghouse introduction. (Bruce)
Lunch Break
4) Overview of metadata collection/management tools. Focus on SMMS -- the metadata collection/management tool used by INSIDE Idaho. (Bruce)
5) ArcInfo 8: What it has to offer for metadata collection. (Frank) 6) Brief training on the metadata tool developed by Frank Roberts and the Coeur
d'Alene Tribe GIS office. (Frank) 7) Making your metadata available through a Clearinghouse Node--INSIDE Idaho.

What I’m going to cover
What is metadata What is the FGDC Standard What is the ISO Metadata Standard What the GIS user need to collect to meet
the standard
What are Metadata?
Shares the same Greek root as metamorphosis - meta means change
Metadata - data about data Metadata describe the origins of & tracks the
changes to geospatial data Metadata answer who, what, when, where,
why, and how about every facet of the data that are being documented
Federal Geographic Data Committee Metadata Standard
Gives us a predefined framework for metadata Provides a common set of terminology to
exchange metadata Executive Order 12906: “requires Federal
agencies to use the standard to document data they produce beginning in 1995.”
Gives us both required and optional elements
International Standards Organization (ISO) metadata standard
The US isn’t the only one thinking about metadata
This standard is currently being established Since the FGDC standard is already been used in
the US, many of the elements for the ISO standard are identical.
ISO will someday replace FGDC, however it is likely that a profile of FGDC standard will be made for the ISO standard.
Why support an metadata standard?
100s of people across US have spent 4 years coming to consensus Tools already exist for (FGDC compliant) metadata entry & capture Defines appropriate use of data Use of data from federal sources Reservation wide data developed with federal dollars Protects your investment
– Without metadata, spatial data becomes useless - externally & internally
Information loses it’s meaning if we are not speaking the same language - we must have a International Standard.
– Great Plains project encompasses 5 states and 2 provinces 89 NSDI nodes already exist to search for FGDC compliant metadata
– Helps people find data
– Avoids duplication of effort
FGDC Metadata explained
No one is required to complete all metadata for the FGDC metadata standard
The standard is broken down into mandatory elements and optional elements
You can select as many as the optional elements as you wish

Summary of mandatory elements of FGDC Metadata
There are a total of 32 items for the mandatory elements of FGDC metadata standard
Only 4 of those items should require you to type something out.
7 of the elements can have a picklist, to select the value
All (21) remaining elements should be automated

$ Funding for metadata $
If you get federal funding to that involves creating GIS data, it is legitimate that you can charge your time to make metadata to that funding
USGS via FGDC offers funding for making metadata (we even received some funding!)
