The Past - FGDC Content Standard for Digital
Geospatial Metadata

• Information Exchange Forum on Spatial Metadata-
  June 16-18, 1992.
• Executive Order 12906, 1994
• EO 13286, 2003
• Content Standards for Digital Geospatial Metadata
  Version 1 1995, Version 2 1998

What is the NAP

• Community profile of ISO 19115 Geospatial
  Information Metadata
• Addresses metadata for geographic products.
• Negotiated content between the ANSI and CGSB
  representatives.
• Format Profile with best practices and
  simplified diagrams for training, UML in annex

6
NAP Metadata Implications Good News

• Multi-level metadata
• Data Series - wetlands
• Dataset - Paducah wetlands
• Feature Type - marsh
• Feature Instance - Mandys Marsh
• Attribute Type - salinity
• Attribute Instance - actual water salinity

ISO Metadata Core Elements
Dataset title Spatial representation type
Dataset reference date Reference system
Dataset responsible party Lineage statement
Geographic location On-line resource
Dataset language Metadata file identifier
Dataset character set Metadata standard name
Dataset topic category Metadata standard version
Spatial resolution Metadata language
Abstract Metadata character set
Distribution format Metadata point of contact
Additional extent info (vert / temp) Metadata date stamp
mandatory

NAP Metadata Content- Domains and Conditionality

• Fewer mandatory elements
• Fixed domains and code lists in place of free
  text to control vocabulary and improve discovery
• More optional elements
• Increased use of modular content

extent citations time period responsible
partycontact address online resource and
more
27
NAP Metadata New (non-CSDGM) Content

• International elements
• Data / Metadata Language
• PT Locale- to record other languages used in the
  metadata
• Lacking elements
• ISO Topic Category 19 standardized subject
  categories to facilitate data discovery
