3. Implementation of ISO Metadata in Science Data Products ISO Metadata Representation ISO XSD Schema encoding specified in ISO 19139:2007 Geographic information – Metadata – XML schema implementation Dictates the serialization of the ISO metadata model Ultimate ISO goal A global standard model in a global standard format The challenge Generate metadata that conforms to the model and is complies with standard serialization Generate software that leverages specific ISO implementations to extract and interpret the model in the proper serialization 2014-07-09 © California Institute of Technology.
