  1. Warning! <xml/> will be visible! ISO Component Management May 19, 2014 NOAA Enterprise Metadata Meeting Anna.Milan@noaa.gov

  2. Docucomp Overview • component management system • part of the EMMA* suite of tools • searchable • stores XML blobs in an oracle db • record and collection services • translation friendly *Enterprise Metadata Management Architecture

  3. Why? • normalization of metadata content • easy to update content across multiple records 744 components reused 564,546 times across all NOAA metadata records

  4. Examples of In/Consistency

  5. Examples of In/Consistency

  6. Definitions Component • re-useable “chunk” of xml Composite Record • a complete metadata record. Record Set • a collection of related metadata files generally organized by program.

  7. 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.

  8. 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

  9. How do I start?

  10. Search First for existing components that can be used

  11. How do I make a new component?

  12. Copy Existing Component

  13. Edit and Validate in XML Editor Delete Previous UUID!

  14. Use MEME* to author component *Metadata Editing Made Easy

  15. 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" codeListValue="search"> search </gmd:CI_OnLineFunctionCode> </gmd:function></gmd:CI_OnlineResource>

  16. Component Example (HTML)

  17. Insert XML into Docucomp

  18. Save Component in Docucomp

  19. How do components integrate with composite records?

  20. Xlink to Component Unresolved: <gmd:onLine xlink:href="http://www.ngdc.noaa.gov/docucomp/eac4bad6-f579-4d6a-bd74-1821f2f02959" xlink:title="DEM text search"/> Resolved: <gmd:onLine xlink:title="DEM text search"> <gmd:CI_OnlineResource uuid="eac4bad6-f579-4d6a-bd74-1821f2f02959"> <gmd:linkage> <gmd:URL> http://www....

  21. Resolve

  22. Save Resolved Metadata Record

  23. Batch Processing

  24. Metadata Dashboard Metric Display Options Detailed Diagnostic Reports List of All Components and Consistency Checker List of All Records in WAF

  25. What can I componentize?

  26. Good Candidates for Components • CI_ResponsibleParty • CI_OnlineResource • CI_Citation • MD_LegalConstraints • MD_Keywords • MI_Instrument • MI_Platform • MD_ReferenceSystem

  27. Resources

  28. Metadata Resources • EMMAHomepage • Has links to all our metadata resources • NGDC Metadata Wiki • Go-to-guide for NGDC metadata management • ISO Explorer • Go-to-guidefor ISO metadata • NOAA’s Environmental Data Management Wiki • NCDDC Metadata Training Webinars

  29. More Metadata Resources • Examples and Templates • ISO templates for many data types • Recommended Components for NGDC metadata • Dummy Example • Enterprise Metadata Group • Meets Monthly to share metadata activities • noaa.enterprise.metadata@noaa.gov • Metadata Working Group • Meets weekly to discuss recommended practices and work through tedious mappings
