Information Management
using
Ecological Metadata Language
Corinna Gries - CAP
Margaret O’Brien - SBC
Goal
To provide the ecological community with an extensible, flexible metadata standard
for use in data analysis and for use in data analysis and archiving that will allow
automated machine processing, searching and retrieval.
Ecological Metadata Language - EML
• Introduction– Purpose, Structure, Content
• Management– Editors, Databases, Creation, Maintenance
• Uses– Web Display, Data Access, Data Conversion,
Data Integration
Introduction
• Dublin Core Metadata Initiative • Federal Geographic Data Committee (FGDC)
– Content Standard for Digital Geospatial Metadata (CSDGM) – Biological Profile of the CSDGM (from the NBII)
• International Standards Organization – Geographic Information Standard (ISO 19115)– Date and Time Standard (ISO 8601),
• OpenGIS Consortiums (GML) • Scientific, Technical, and Medical Markup Language (STMML) • Extensible Scientific Interchange Language (XSIL).

• XML-based storage and transfer of metadata
• EML content standard focuses on metadata for identification, analysis, and integration
• accommodates geospatial and non-geospatial data
• strong data typing
• strong access and revision control
• distinction between logical format and physical format
