*Enterprise Metadata Management Architecture

Why?• normalization of metadata content• easy to update content across multiple records

744 components

reused 564,546 times

metadata records

Examples of In/Consistency

Examples of In/Consistency

DefinitionsComponent – re-useable “chunk” of xml

Composite Record– a complete metadata record.

Record Set– a collection of related metadata files generally

organized by program.

Definitions

Resolved Record– a metadata file that includes no links to external

content, no references. The output of the resolver.

Unresolved Record– a metadata file that contains references (xlinks)

to components, instead of the component content.

Definitions

Resolver– a tool for resolving components to form a

metadata record without references to remote content.

Xlink– an XML specification that provides methods for

creating internal and external links within an XML document.

UUID– Universally Unique Identifier

HOW DO I START?

Search Firstfor existing components that can be used

HOW DO I MAKE A NEW COMPONENT?

Copy Existing Component

Edit and Validate in XML Editor

Delete Previous

UUID!

Use MEME* to author component

*Metadata Editing Made Easy

Component Example (XML)<gmd:CI_OnlineResource uuid="eac4bad6-f579-4d6a-bd74-1821f2f02959"> <gmd:linkage> <gmd:URL> http://www.ngdc.noaa.gov/dem/squareCellGrid/search </gmd:URL> </gmd:linkage> <gmd:name> <gco:CharacterString> DEM text search tool </gco:CharacterString> </gmd:name> <gmd:description> <gco:CharacterString>Text search tool for locating DEMs.</gco:CharacterString> </gmd:description> <gmd:function> <gmd:CI_OnLineFunctionCode codeList="http://www..../gmxCodelists.xml#CI_OnLineFunctionCode"

Save Component in Docucomp

HOW DO COMPONENTS INTEGRATE WITH COMPOSITE RECORDS?
