ISO Metadata Is flexible Depicts relationships between datasets and collection level (parent/child relationships) Standardizes descriptors through the use of codelists Accommodates new technologies (such as documenting services) Accommodates International scope Undergoes revision/review in 5 year cycles

Organization and Content of ISO ISO is organized in Sections and Packages Section: Groupings of similar information Package: Logical groupings of elements found in multiple locations within Sections

Main Sections of ISO Metadata Metadata Information (MD_Metadata) Root element that contains information about the metadata itself. Root contains main sections. Spatial Representation Information (gmd:spatialRepresentationInfo) geospatial representation of a resource Reference System Information (gmd:referenceSystemInfo) spatial and temporal reference systems used in the resource Metadata Extension Information (gmd:metadataExtensionInfo) user specified extensions to the metadata standard used to describe the resource Identification Information (gmd:identificationInfo) uniquely identify a resource or resources Content Information (gmd:contentInfo) physical parameters and other attributes contained in a resource Distribution Information (gmd:distributionInfo) who makes a resource available and how to get it Data Quality Information (gmd:dataQualityInfo) quality and lineage (including processing steps and sources) of a resource Portrayal Catalogue Information (gmd:portrayalCatalogueInfo) collection of defined symbols used to depict, to humans, features on a map Metadata Constraint Information (gmd:metadataConstraints) constraints on the use of the metadata and the resource it describes Application Schema Information (gmd:applicationSchemaInfo) application schema used to build a dataset Metadata Maintenance Information (gmd:metadataMaintenance) maintenance of the metadata and the resource it describes
