Metadata Issues  Problem: Focus on data/servicesFocus on data/services “not important”“not important” Too much troubleToo much trouble  Solution: Must be integral part of operations Part of data collection process Easy to do Stay with the data Life-cycle support

Design Goals for Metadata in ArcCatalog  Make it easy to create and use metadata Create editors that are easy to useCreate editors that are easy to use Create and update metadata automatically with a dataset’s current propertiesCreate and update metadata automatically with a dataset’s current properties

Design Goals for Metadata in ArcCatalog  Support ISO metadata content standard out of the box Support other standards through customizationSupport other standards through customization  Support metadata for everything Geographic data, nonspatial files, folders, databases, etc.Geographic data, nonspatial files, folders, databases, etc.

Design Goals for Metadata in ArcCatalog  Metadata is part of the data Travels with the data when copied, moved, renamed, or exportedTravels with the data when copied, moved, renamed, or exported Doesn’t get lostDoesn’t get lost  Use open, flexible, industry- standard technology Metadata stored in XML formatMetadata stored in XML format

ISO Metadata Tools in ArcCatalog  Editor for typing information  Style sheets for viewing  Synchronizer for updating automatically  Importers and exporters  Translator from one standard to another

ISO Metadata Editor  Wizard-based editor designed for the average person  Elements are introduced by plain language  Navigate with Next and Back buttons or go directly to a page using the TOC  Handles core elements as defined by 19115

ISO Synchronizer  Automates much of the work for metadata collection and maintenance  Vector and raster information, spatial reference, etc. ArcIMS Services Automatically senses and records properties Files

Publishing Metadata  Publish metadata by copy/paste or drag/drop Copy/Drag the metadata onto the Metadata Server folder to publishCopy/Drag the metadata onto the Metadata Server folder to publish  Metadata is “copied” to the server A new record is created in the database for this metadata data setA new record is created in the database for this metadata data set Contents are indexed to optimize search and retrievalContents are indexed to optimize search and retrieval  Must have publishing privileges

Searching for Geospatial Data Metadata Catalog ArcCatalog HTML or Java Clearinghouse Z39.50 Metadata Explorer Metadata Explorer Geography Network

Searching Metadata  Use ArcCatalog or the Web-based Metadata Explorer as the search client.  Searching a metadata repository is possible in two ways: 1.Via selected search criteria (keyword, extent, content type, data theme). 2.By browsing through the hierarchy of documents.

  ISO Standard Based on a harmonized object model Designed to support geographic information Designed to fill a broad range of requirements Designed to serve the global community in a multinational multi-language environment Recommended core with a full comprehensive profile   Metadata in an ISO standard Allows expanded networks Provides a common understanding Global Interoperability Summary ISO Metadata  Metadata is absolutely essential for all aspects of spatial data handling Locate Evaluate Extract Employ  ISO development Based on a solid foundation of national, regional, and information community standards Has broad global participation Has gone through formal development cycles The Foundation for a Global Spatial Data Infrastructure
