North American Profile: Partnership across borders. Sharon Shin, Metadata Coordinator, Federal Geographic Data Committee Raphael Sussman; Manager, Lands Information Ontario
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
Net Benefits of Metadata • For data distributors: Metadata makes data sharing: • easier, • less risky, and • cheaper • For all enterprises: Metadata reduces the cost of losing information about spatial data assets, thereby • increasing the usability of those assets over time. • Sustaining and value of the assets
Interoperability Issues(Service Metadata) • Portals, using Internet, Intranet, and Extranet • displays and/or integrates data normally intended for use with specific, disparate applications without those applications • uses data from multiple sources without clearly defining quality or source of individual features
Interoperability Issues • Web Services • Discovery of Services (including data services) by computers rather than by people • Simultaneous incorporation of live data from many sources (eg Web Map Services) originally created or stored in different formats, models, or quality
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
Metadata Entity Set Information Identification Information Constraints Data Quality Information Maintenance Information Spatial Representation Information Reference System Information Content Information Portrayal Catalogue Information- new Distribution Information Application Schema Information - new Major Classes
ISO Metadata / CSDGM Similar Content • Conditionality • Same Abstract Metadata Standard Name • New terminology and definitions CSDGM = Originator ISO = Responsible Party - Role
ISO Metadata: Core Elements mandatory
NAP: Essential Metadata • Requires reviewing the entire standard to determine what is minimal metadata for each user. • Metadata Record Information – 7 mandatory • Identification Information- 3 mandatory All optional shown with the number of mandatory attributes/subclasses: • Data Quality 1 • Maintenance Info 1 • Descriptive Keywords 1 • Resource Constraints 0 +1 • Aggregate Info 1 • Spatial Representation Info 4 + 7 • Reference System Info 1 • Content Info 2 or 3 + 2 • Distribution Info 2 +1

What is ISO 19115 Geospatial Information - Metadata • Provides a schema for describing geographic data and services. • Applies to multiple levels of geographic information. • Defines a core set of metadata required to serve the full range of applications. • Allows for multilingual metadata • Establishes: • terminology • definitions • conditionality

NAP: Essential Metadata • Requires reviewing the entire standard to determine what is minimal metadata for each user. • Metadata Record Information – 7 mandatory • Identification Information- 3 mandatory All optional with the number of mandatory attributes/subclasses: • Data Quality 1 • Maintenance Info 1 • Descriptive Keywords 1 • Resource Constraints 0 +1 • Aggregate Info 1 • Spatial Representation Info • 4 + 7 • Reference System Info 1 • Content Info 2 or 3 + 2 • Distribution Info 2 +1
ISO 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
