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
ISO 19115
•Enables describing:– Geospatial data sets.– Maps.– Non-geospatial resources.
– Services: portals, web mapping services.
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.
ISO 19115 and other ISO Standards
• Language Codes• County Codes• Conceptual Schema Language• Profiles• Spatial Schema• Temporal Schema• Rules for Application Schema• Methodology for Feature Cataloging• Spatial Referencing by Coordinates• Quality Principles • Quality Evaluation Procedures
• Metadata, Technical Corrigendum 1• Encoding• Services• Geographic Information Services • Geodetic codes and Parameters• Location Based Services- Tracking and Navigation • GML• XML• OGC’s Web Services Common Specification
What is different/same between FGDC CSDGM and the NAP?
Organization and Terminology
•FGDC – Sections– Elements – Compound Elements– Domains
•ISO / NAP – Classes– Subclasses– Attributes – Domains
Obligation Terminology: FGDC to ISO
•FGDC:– Mandatory– Mandatory-if-applicable– Optional
•ISO/NAP:– Mandatory– Conditional– Optional
FGDC CSDGM Graphic Representation
ISO UML Diagrams
Decisions?:
•Stylize
•Simplify
•Colorize

Major NAP Classes
• Metadata Entity Set Information• Identification Information
–Dataset Identification–Service Identification
• Constraints• Data Quality Information • Maintenance Information
• Spatial Representation Information• Reference System Information• Content Information• Portrayal Catalogue Information• Distribution Information• Application Schema Information
Metadata Entity Set Information
• File Identifier (M) • Language (M)• Character set (M)• Parent Identifier • Hierarchy Level (M)• Contact (M)• Date Stamp (M)
• Metadata Standard Name (M)• Metadata Standard Version• Data Set URI• Locale (C)
Data Quality
• Attribute Consistency • Logistical Consistency• Completeness Report • Positional Accuracy• Lineage
• Scope (M) • Report (C)
–Completeness–Logical Consistency–Positional Consistency–Thematic Accuracy –Temporal Accuracy
• Lineage (C)–Source–Process Step
CSDGM NAP
Maintenance Information
• Maintenance and Update Frequency (M) – code list
• Date of Next Update • User Defined Maintenance
Frequency • Updated Scope• Update Scope Description• Maintenance Note• Contact – responsible party
Service Identification
• Attributes (5 Mandatory)• Resource Maintenance Information• Graphic Overview• Descriptive Keywords• Resource Specific Usage• Resource Constraints• Aggregation Information• Operates On• Contain Operation (M)
Application Schema
• Name (M)• Schema language (M)• Constraint language (M)• Schema ASCII• Graphics file• Software development file• Software development file format
Portrayal Catalogue
• Information to reproduce a map:– Line weight – Color– Font– Etc.
Metadata Entity Set Information
7 mandatory attributes
• Identification Information M (M6/)– Data Identification C (M6/) – Service Identification C (M5/M1)
• Constraints O ()• Data Quality Information O(M1/) • MD Maintenance O (M1/)• Spatial Representation O ()• Reference System Information C (M1/M1)• Content Information O (C2/)• Portrayal Catalog O (M0 / M1)• Distribution Information O () • Application Schema O(M3/)
Class Name – Obligation (Mandatory attributes / Mandatory subclasses)
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 2
• Metadata as a corporate resource.– Data on hand
• Data assessment • Data update
– Scheduling– Estimating staffing– Estimating time
– Data to be procured
NAP Editing Committee: Next Steps
• Review of Comments Fall 2007.• Review of adjudication of comments.• Final edit prior to submission to standards bodies.
• US: Submission to American National Standards Institute: Fall 2007.
• ANSI review, vote, Adoption….?. • FGDC Standards Working Group…
FGDC Metadata Working Group: Next Steps
• Develop NAP training materials content outline for WG members review.
• Develop NAP modules for download.– Intro to ISO 19115– Intro to NAP– NAP Content
FGDC to ISO Conversion Tool Release – Fall 2007
• XML- conversion format. • Conversion tool format: XSLT.• Standalone.• Plan to include source code. • Conversion tool to be delivered via
shareware site. • Announced through FGDC.gov and
FGDC Metadata Working Group.
What to do for now• Monitor fgdc.gov for Public Review
announcement.– Announcement made directly to FGDC Metadata
WG.
• Join/monitor FGDC Metadata Working Group/website
• NAP Training: Monitor http://www.fgdc.gov/training/nsdi-training-program/online-lessons
• Until ANSI adoption and FGDC recognition /adoption of NAP– Continue use of FGDC CSDGM– Post metadata to clearinghouses– Register clearinghouses to geodata.gov
(Geospatial One-Stop).
