The US is in the final stages of adopting a national geospatial metadata standard. While the FGDC geospatial metadata standard was a federal standard recognized by most state and local governments, the forthcoming standard will be an American National Standards Institute (ANSI) implementation of the International Organization for Standardization (ISO) Geographic Information - Metadata (standard). This new standard, while based heavily on the FGDC Content Standard for Digital Geospatial Metadata (CSDGM) version 2.0, introduces new formats and content that incorporate more robust data structures, e.g. flexibility, while at the same time addressing the need for increased standardization in individual element values, e.g. domains. Get a sneak preview of these new features as well as the draft guidance workbook under development by the FGDC.
North American Profile (NAP) StatusUS is in the final is in the final stages of adopting a national
geographic metadata standard– Content Standard for Digital Geospatial Metadata aka
‘FGDC’ metadata standard is a federal standard– NAP is an American National Standards Institute (ANSI)
standard with broader applicability– ANSI approval is expected in early 2009
we are herestart finish
scale determined by ISO, ANSI, INCITS L1 and various other acronyms
Transition to the NAP– transition will be staged as it as with the FGDC standard
• apply to new metadata records
• translate existing metadata records
– FGDC is working with NSGIC, URISA and others to develop effective transition strategies
– translation applications under development by FGDC, Intergraph, ESRI and several international metadata application developers
New or Robust Sections - Resource Maintenance
added functionality - Data Quality
increased structure
What’s New with the NAP?New Elements
International elements• Data / Metadata Language
Technical elements• Character Set Encoding
Extended elements• CSDGM = geographic and temporal extent
• NAP = geographic, temporal, & Vertical Extent
Needed elements• Topic Category – 19 standardized subject categories to facilitate
data discovery
What’s New with the NAP?Conditionality
Fewer mandatory elements• Core contains only 7 mandatory elements• Dataset Title• Dataset Reference Date• Dataset Language• Dataset Topic Category• Abstract• Metadata Point of Contact• Metadata Date Stamp
...includes far more optional elements
What’s New with the NAP?Domains
More standardized domains and code lists in place of free text to control vocabulary and improve discovery
• Contact Role = author, distributor, custodian, point of contact…
• Topic Category = transportation, environment, elevation, biota….
• Online Function = download, information, offline access…
• Keyword Type = theme, place, stratum, temporal…
• Maintenance Frequency = continual, daily, weekly, annually…
• Progress = completed, archived, obsolete, ongoing, planned…
• Topic Category = transportation, environment, oceans, biota…
What’s New with the NAP?Content
Includes elements to document geospatial services• Web Mapping Services• Geospatial Data Catalogues and Portals• Other
Does not CURRENTLY include Entity & Attribute documentation
• documented by ISO 19110: Feature Catalog
• NAP team intends to extend NAP to include Feature Catalog in next version
What’s New with the NAP?Multilevel Metadata
Metadata can be created for:• Data Series - wetlands• Dataset - Paducah wetlands• Feature Type - marsh• Feature Instance - Mandy’s Marsh• Attribute Type - salinity• Attribute Instance - actual % water salinity

Staying Current1. Join the FGDC Metadata Working
Group– quarterly telecons to discuss federal and stakeholder
metadata activities and issues– regular calls for review/input– regular calls for task/committee participationSend email to Sharon ([email protected]) include:– name– organization– ‘please add my email to the Metadata Working Group’
Staying Current2. Participate in Resource Materials
Reviews– transition guidance and strategies– graphical representation– workbook/reference doc– otherSend email to Lynda ([email protected]) include:– name– ‘I am interested in contributing to the (resource)
development and review’
