North American Profile - ISO 19115
• Goal.
  – Meet the geospatial metadata implementation
    needs of the US through the development of a
    Profile guidance document.
• Objectives.
  – Comprehensive profile.
  – Identical content with Canadian Profile.
  – Release by ANSI same date and time as CSB.
      • Results in North American Profile: NAP
North American Profile: Approach
• No new attributes.
• Increase obligations.
• Modify codelists…deprecate
• Create new codelists for free text fields.
• Recommend structure with in text fields
  e.g. address.
• Modify/simplify diagrams.
• Adding best practices to guide
  implementation.

FGDC CSDGM and the NAP?

That was NAP Content, now
          what?
              Best Practice
• Create metadata as the project progresses
  – Information is at hand
  – Brain drain is at a minimum
  – Create Template
  – Internal use
  – Contracted Data
• Create Template
  – Internal use
  – Contracted Data
              Best Practice
• Metadata as a corporate resource.
  – Data on hand
    • Metadata assessment
    • Metadata Maitenance
       – Scheduling
       – Estimating staffing
       – Estimating time
  – Data to be procured
    • Contract Metadata
    • Provide contractor with template to assure content
      level
    • Metadata Maintenance
Ready to go?

  Not Quite
The NAP is a national standard but
• The FGDC Standards Working Group will
  review the NAP and the processes by
  which it arrived
• The Standards WG make
  recommendations to the FGDC
  Coordination Group and Steering
  Committee to reject, adopt, or recognize
  the NAP.
  Do you have entity and attribute
           information
• No                     • Yes
  – Go ahead,              – Feature Catalog?
  – Use the editor       • For the present
    selected               – Create metadata using
  – Create Metadata!!!       the NAP AND
                           – Log and attach entity
                             and attribute
                             information using
                             CSDGM Section 5
     ISO 19110 Methodology for
          Feature Catalog
• Allows for full description of features
  (entities and attributes)
• New work item by INCITs L1
• Scheduled completion by next summer.
          Metadata Editors
• Can you create metadata without an
  editor?
• Check the ISO/ NAP editor review on
  FGDC.gov
   http://www.fgdc.gov/metadata/geospatial-
   metadata-tools
   Wait, I have biological data
• The FGDC Biological Data Working
  Group is staged to present a profile to the
  NAP for biology
• The National Biological Information
  Infrastructure is gathering a group from the
  community to develop a profile for biology.
• Process start and input will be requested
  from the biological community as soon as
  the NAP has final approval.
Wait, I have existing
     metadata.
 Do I need to re-write my
        metadata?

    What’s similar/new with NAP
    Metadata
•   Content
    – CSDGM similar and new elements
    – Domains and conditionality
    – Essential, as opposed to core, metadata
•   Format
    – UML / XML
    – Multi-level metadata-
       • Feature to Dataset Series or Service
ISO Metadata / CSDGM Similar
          Content
– Conditionality
– Same
   Abstract
– New terminology and definitions
   CSDGM = Originator
   ISO = Responsible Party - Role
