BEYOND THE BASICS Tailoring Metadata for Your Needs

Fine Tuning Your CSDGM Use of Thesauri or Keywords CSDGM Profiles Biological Shoreline CSDGM Extensions Remote Sensing Local Extensions Different Standards Use of Thesauri or Keywords CSDGM Profiles Biological Shoreline CSDGM Extensions Remote Sensing Local Extensions Different Standards

Why Tailor? Can use discipline specific thesauri CSDGM profile or extension may better fit your dataset Dataset specific guidelines Organization or Community guidelines Publishing or harvesting purposes Can use discipline specific thesauri CSDGM profile or extension may better fit your dataset Dataset specific guidelines Organization or Community guidelines Publishing or harvesting purposes

What are Thesauri? Discipline specific vocabularies Describes data in a standardized manner Tools in which to manage the knowledge held within resources and the relationships between their entries Goal is to facilitate interoperability and enable data discovery Discipline specific vocabularies Describes data in a standardized manner Tools in which to manage the knowledge held within resources and the relationships between their entries Goal is to facilitate interoperability and enable data discovery

Profiles Profiles extend the base standard by adding metadata elements to meet their specific community metadata requirements Examples of profiles of CSDGM: Biological Data Profile of the CSDGM Metadata Profile for Shoreline Data Profiles extend the base standard by adding metadata elements to meet their specific community metadata requirements Examples of profiles of CSDGM: Biological Data Profile of the CSDGM Metadata Profile for Shoreline Data

Biological Profile Objective is to increase the FGDC CSDGM utility for documenting biological resources data and information Helps broaden the understanding and implementation of the FGDC metadata content standard within the biological resources community Objective is to increase the FGDC CSDGM utility for documenting biological resources data and information Helps broaden the understanding and implementation of the FGDC metadata content standard within the biological resources community

Extensions Extensions are used when some data does not fit into a particular section Example of extensions: Remote Sensing Extensions include metadata describing the sensor, platform, the information need to determine the geographical location, and the method and process of deriving geospatial information from the raw telemetry Extensions are used when some data does not fit into a particular section Example of extensions: Remote Sensing Extensions include metadata describing the sensor, platform, the information need to determine the geographical location, and the method and process of deriving geospatial information from the raw telemetry

Markup Languages Languages used to categorize, label, and organize data content Community driven (are often discipline specific) Examples include: XML SensorML EML Languages used to categorize, label, and organize data content Community driven (are often discipline specific) Examples include: XML SensorML EML

Different Standards Ecological Metadata Language (EML) MARC21 – MARCXML Dublin Core – DCMI ISO and related ISO standards

Mapping Standards Other standards can often be “mapped” or “crosswalked” to compare to FGDC data Examples Marc21 Dublin Core ISO or Other standards can often be “mapped” or “crosswalked” to compare to FGDC data Examples Marc21 Dublin Core ISO or
