461 461  
462 462  **container-object-id** is the identifier of an intermediary object that contains the actual object which the URN is identifying. It is not mandatory as many actual objects do not have an intermediary container object. For instance, a [[Code>>doc:Glossary.Code.WebHome]] is in a maintained object (Codelist) and has no intermediary container object, whereas a MetadataAttribute has an intermediary container object (MetadataAttributeDescriptor) and may have an intermediary container object, which is its parent MetadataAttribute. For this reason, the container object id may repeat, with each repetition identifying the object at the next-lower (% style="color:#e74c3c" %)level(%%) in its [[hierarchy>>doc:Glossary.Hierarchy.WebHome]]. Note that if there is only a single containing object in the model then it is NOT included in the URN structure. This applies to AttributeDescriptor, DimensionDescriptor, and MeasureDescriptor where there can be only one such object and this object has a fixed id. Therefore, whilst each of these has a URN, the id of the AttributeDescriptor, DimensionDescriptor, and MeasureDescriptor is not included when the actual object is a DataAttribute or a Dimension/ TimeDimension, or a Measure.
463 463  
464 464  Note that although a [[Code>>doc:Glossary.Code.WebHome]] can have a parent [[Code>>doc:Glossary.Code.WebHome]] and a (% style="color:#e74c3c" %)Concept(%%) can have a parent (% style="color:#e74c3c" %)Concept(%%) these are maintained in a flat structure and therefore do not have a containerobject-id.

In the general syntax of the URN all intermediary objects in the structure (with the exception, of course, of the maintained object) are shown as a contained object. An example here would be a [[Category>>doc:Glossary.Category.WebHome]] in a CategoryScheme. The [[Category>>doc:Glossary.Category.WebHome]] is hierarchical, and all intermediate [[Categories>>doc:Glossary.Category.WebHome]] are shown as a contained object.
