Ecological Metadata Languageand related standards

• KNB Data Management Tools Workshop
• Matthew Jones
• National Center for Ecological Analysis and
  Synthesis
• University of California, Santa Barbara

2
Related metadata standards

• Dublin Core Element Set
• Corresponds roughly to eml-resource
• Content Standard for Digital Geospatial Metadata
  (CSDGM)
• Federal Geographic Data Committee (FGDC)
• Corresponds to eml-spatialRaster,
  eml-spatialVector,eml-spatialReference
• Overlaps in other modules (eml-resource)
• Biological Data Profile (BDP) of the CSDGM
• Biological Data Working Group of the FGDC
• Shares structure for taxonomicCoverage,
  geologicAge, and ascii table structures
• ISO 19115 Geographic information Metadata
• Incorporated in the eml-spatial modules
• Eml-party derived from ISO 19115
• Darwin Core
• Partially overlaps with eml-coverage
• Geography Markup Language (GML)

Conversion among standards

• EML represents a superset of
• BDP
• CSDGM
• ISO 19115 (I think)
• Dublin Core
• Theoretically can convert from EML to those
• Extensive overlap among all of these standards
• Practically, have conversion script for
• EML ? BDP
• Uses XSLT so can be used in a variety of software
  
• Need to incorporate this into tools like Morpho
  and Metacat
• Need other conversion scripts!
