What are metadata?
“data about data”
“information about data”
The “who”, “what”, “where”, “when”, and “how”
Information contained in the library card catalog system
Title, author, publication date, number of pages, keywords for a search system, etc.
Critical component of a complete data setNo data set should be considered
complete without fully-developed, well-written metadata.
When should you create metadata?
When you want to share data sets with others
When you want to publicize data sets
When you want others to be able to decide whether or not they want to use the data set
When you want to preserve a data sets’ usefulness through timeFor data sets that represent a large commitment in terms of effort and
cost, this is particularly important
When you want to provide access to datasets through search engines or portals
“Data discovery, assessment, access, use, and management”
How do I create metadata?
FGDC CSDGM Standard
www.fgdc.gov
Dublin Core Standard
Build a template
Adopt all mandatory fields from the standard you choose
Adopt all ‘mandatory if applicable fields’ that are pertinent
Identify ‘optional fields’ of interest Create a pilot record from a draft template for
review and revision
Don’t create you own version of a standard
Read the Introduction to Oregon Metadata Standard at http://www.oregon.gov/DAS/EISPD/GEO/standards/docs/Metadata_Opportunity.pdf
Check out the Federal Geographic Data Committee (FGDC) Web site
ISO 19115 Standard
FGDC metadata standard: overview
Seven Major Metadata Sections:• Section 1 – Identification Information*• Section 2 – Data Quality Information• Section 3 – Spatial Data Organization Information• Section 4 – Spatial Reference Information• Section 5 – Entity and Attribute Information• Section 6 – Distribution Information• Section 7 – Metadata Reference Information*
Three supporting Sections• Section 8 – Citation Information*• Section 9 – Time Period Information*• Section 10 – Contact Information*
* Minimum required metadata
FGDC Graphic Representation
A tool to visually describe the structure of the metadata standard
Uses color and relationships to show information: http://www.fgdc.gov/csdgmgraphical/index.html
What is Mandatory? What is Not?
Yellow
Mandatory: must be provided
Green
Mandatory if applicable: must be provided if the data set exhibits the defined characteristics
Blue
Optional

How do you write good metadata?
Document for a general audience
Be consistent in style and terminology
Write simply but completely
Have someone else review your file
Define technical terms and acronyms
Don’t use jargon
Good metadata: The Title
Critical in helping readers find your data
Includes: what, where, when, who
If data are officially published, in the title include:
Series name
• Issue number
• Name of publisher
• Location of publisher
Examples: Ace Basin, South Carolina National Estuarine Research Reserve Digital
Line BoundaryGreater Yellowstone Rivers from 1:128,700 Forest Visitor Maps (1961-
1983)
Good metadata: Select keywords wisely
Use unambiguous words
Use descriptive words
Fully qualify geographic locations
Identify keyword thesaurus
• The Oregon Metadata Keyword Thesaurus identifies keywords, some Oregon specific, that may be used and cited for metadata.
http://gis.oregon.gov/thesaurus
Good metadata: Review your final product
Have someone else read it
If you’re the only reviewer, put it away and read it again later
Check for clarity and omissions
Can a novice understand what you wrote?
Does the documentation present all the information needed to use or reuse the data
Are any of the pieces missing?
