Metadata
• What is it?– Structured information that describes a resource– NISO: “metadata is structured information that
describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource”
• Why is it important?– Enables a resource or data to be easily discovered– Good metadata will help others understand and use
your data

Metadata Answers…Who created the data?Who maintains it?When were the data collected? When were
they published?Where was it collected (geographic location)?What is the content of the data? The structure?Why were the data created?How were they produced/analyzed?

Critical Roles of Metadata
• Data Discovery – To be able to identify important data sets
• Data Retrieval– To know how and where to access data
• Data Use– To know enough details about how the how the data were
collected and stored• Data Archiving– Data can grow more valuable with time, but only if the
critical information required to retrieve and interpret the data remains available

Metadata FormatsStructured documentation in XML format for use in discovery programs (searching), examples:
– DDI– Data Document Initiativehttp://www.ddialliance.org/
– FGDC– Geospatial Metadata Standardhttp://www.fgdc.gov/metadata/geospatial-metadata-standards
– EML– Ecological Metadata Languagehttp://knb.ecoinformatics.org/software/eml/
