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

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).
