73 73  In brief, a MetadataStructureDefinition ([[MSD>>doc:xwiki:Glossary.Metadata structure definition.WebHome]]) defines the MetadataAttributes, within an MetadataAttributeDescriptor, that can be associated with the objects identified in the [[Metadataflows>>doc:xwiki:Glossary.Metadataflow.WebHome]] and MetadataProvisionAgreements that refer to the [[MSD>>doc:xwiki:Glossary.Metadata structure definition.WebHome]]. The [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] of the MetadataAttributes is specified within the MetadataAttributeDescriptor.
