1 2008 EPA and Partners Metadata Training Program: 2008 CAP Project Geospatial Metadata: Intermediate Course Module 3: Metadata Catalogs and Geospatial One Stop (GOS)

2 EPA and Partners Metadata Training Program: 2008 CAP Project 2 Training Structure Agenda How do I share my information with others? Overview of catalog implementation options Implementation considerations Catalog characteristics EPA Implementation Example Overview of Geospatial One Stop (GOS) Materials Metadata catalog comparison spreadsheet Summary

3 EPA and Partners Metadata Training Program: 2008 CAP Project 3 Learning Objectives After completing this module the student can: Describe what types of catalog implementations are available List some pros and cons of each option Describe three key considerations for choosing a catalog implementation Describe the features that GOS has to offer Describe how to register a catalog at GOS

4 EPA and Partners Metadata Training Program: 2008 CAP Project 4 Metadata Catalogs and Sharing How do I share my information with others? Implementations Website Catalog Web Accessible Folder (waf) Z39.50 metadata clearinghouse Metadata Service Geospatial Data Portal Internet Metadata Collection User Query Internet / Intranet Data Set

5 EPA and Partners Metadata Training Program: 2008 CAP Project 5 Metadata Catalogs and Sharing Catalog Implementation Considerations What are your needs? Ease of implementation and maintenance? Freeware? Integration with COTS products? Large-scale, robust enterprise catalog? Advanced administration & management? Contribute to NSDI and GOS? Others?

6 EPA and Partners Metadata Training Program: 2008 CAP Project 6 Catalog Characteristics Website Catalog Simple framework; usually not a lot of overhead to maintain* Users do not need special tools for access Usually easy to use with browse access for data layers May not require special software to implement Static pages may not be suitable for large collections of data May not readily lend itself to sharing with other catalogs * If you have a lot of data/metadata that change frequently this option may not be simple to maintain Example from MassGIS website

7 EPA and Partners Metadata Training Program: 2008 CAP Project 7 Catalog Characteristics Web Accessible Folder (WAF) Simple framework; not a lot of overhead to maintain Users do not need special tools for access Does not require special software Interface may not be intuitive for various users May want to customize for ease of use EPA Example: Readily lends itself to sharing with GOS & NSDI

8 EPA and Partners Metadata Training Program: 2008 CAP Project 8 Catalog Characteristics Z39.50 metadata clearinghouse Typically relatively simple to set up and maintain Works with both the NSDI Clearinghouse and GOS A web based interface should be developed for human interaction Can be implemented using freeware Isite software is free; GeoNetwork is open-source ESRIs ArcIMS Metadata Service can be configured to use Z39.50 connector More Information: s/getisite s/getisite

9 EPA and Partners Metadata Training Program: 2008 CAP Project 9 Catalog Characteristics Metadata Service May require more overhead and software/hardware to set up and manage Users may need special tools for access unless a web based interface is created for interacting with the service Usually readily accessible from ArcCatalog Provides browse capability for records Usually readily lends itself to sharing with other catalogs and clearinghouses Requires special software; a common implementation is the ESRI Metadata Service which comes with ArcIMS.

10 EPA and Partners Metadata Training Program: 2008 CAP Project 10 Catalog Characteristics Geospatial Data Portal Requires the most overhead and software/hardware to set up and manage Usually includes the most powerful tools for metadata management Group access Distributed management tools Harvesting Usually readily accessible from ArcCatalog Readily lends itself to sharing with other catalogs and clearinghouses Requires special software; common implementations include ESRI Geospatial Portal Toolkit and GeoNetwork Some Examples: Geography Network, Geospatial One Stop, EPAs GDG, Conservation GeoPortal

11 EPA and Partners Metadata Training Program: 2008 CAP Project 11 EPAs GeoData Gateway Catalog Implementation Example EPAs GeoData Gateway (GDG) Implemented initially in 2006 Key out of the box capabilities search user management map viewer harvesting ArcCatalog integration Customized to meet EPAs needs Group Management Single Sign On Record-level security (external access) Additional Considerations Policies and procedures Communication, outreach & training

12 EPA and Partners Metadata Training Program: 2008 CAP Project 12 EPAs GeoData Gateway Demonstration

13 EPA and Partners Metadata Training Program: 2008 CAP Project 13 The GOS Portal – What is GOS? An intergovernmental project supporting E-Gov initiative seeking to: Encourage collaboration Leverage geospatial resources and best practices Improve geospatial resource access, re-use and sharing Resources available at GOS Live Data and Maps Downloadable Data Offline Data Documents

14 EPA and Partners Metadata Training Program: 2008 CAP Project 14 The GOS Portal – What features does it offer? Search & Discovery Access Resources View Data Services Browse Communities Post data acquisition plans Publish metadata Manage Metadata

15 EPA and Partners Metadata Training Program: 2008 CAP Project 15 Registering with GOS How do I publish to GOS? Create an account Publish metadata Harvesting Online Metadata Creation Form Online Upload Metadata File Utility Manage metadata

16 EPA and Partners Metadata Training Program: 2008 CAP Project 16 Registering with GOS Harvesting Options: Z39.50 server Open Archive Initiative for Harvesting Protocol (OAI-PMH) ArcIMS Metadata Server Web-accessible folder (WAF) Catalog Service for the Web (CS-W)

17 EPA and Partners Metadata Training Program: 2008 CAP Project 17 Registering with GOS Publishing Options Online Metadata Creation Form Stores metadata at GOS Online Upload Metadata File Utility XML or SGML

18 EPA and Partners Metadata Training Program: 2008 CAP Project 18 Registering with GOS Manage Metadata Publishers manage their own collections View records Download Edit Delete Check online linkage Transfer ownership

19 EPA and Partners Metadata Training Program: 2008 CAP Project 19 FGDC NSDI Components GOS NSDI Clearinghouse EPAs Public Website and Metadata Service Z GeoNetwork ESRI Portal Toolkit Metadata Catalogs and GOS

20 EPA and Partners Metadata Training Program: 2008 CAP Project 20 Registering with GOS Metadata Catalogs and GOS Quiz! Name one benefit and one drawback of implementing a geospatial portal as opposed to implementing a website catalog Contents at a Web Accessible Folder (WAF) can be readily viewed through ArcCatalog True False At GOS, a user cannot: A.Search for geospatial resources B.Access geospatial resources C.Post data acquisitions D.Purchase data using a debit card
