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 CollectionUser Query

Internet / Intranet

Data Set

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


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



Web Accessible Folder (WAF)Simple framework; not a lot of overhead to maintainUsers do not need special tools for accessDoes not require special softwareInterface may not be intuitive for various users

May want to customize for ease of useEPA Example: http://geodata.epa.gov/WAF/Readily lends itself to sharing with GOS & NSDI

8



Z39.50 metadata clearinghouseTypically 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

ESRI’s ArcIMS Metadata Service can be configured to use Z39.50 connector

9



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



Geospatial Data PortalRequires 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, EPA’s GDG, Conservation GeoPortal

11


EPA’s GeoData Gateway

Catalog Implementation ExampleEPA’s GeoData Gateway (GDG)

Implemented initially in 2006

Key out of the box capabilities search user management map viewer harvesting ArcCatalog integration

Customized to meet EPA’s needs Group Management Single Sign On Record-level security (external access)

Additional Considerations Policies and procedures Communication, outreach & training

The GOS Portal – www.geodata.gov

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 DataOffline DataDocuments

14


The GOS Portal – www.geodata.gov

What features does it offer?

Search & Discovery

Access Resources

View Data Services

Browse Communities

Post data acquisition plans

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 resourcesB. Access geospatial resourcesC. Post data acquisitionsD. Purchase data using a debit card
