NOTE: A consequence of this is that collections may be directly created but not edited
NOTE: All subresources can be created along with resources in flat style

• Parent contains a createable, uneditable collection of mappings
• Mapping contains an uneditable reference to primary
• Mapping contains a creatable, potentially editable reference to secondary (whether relationships can be updated is an open question)
• Secondary does not contain a reference to primary or mapping
• Primary resource has a special query whose parameter is a secondary uuid which returns all primaries related to the secondary; this query is identified by the name of the secondary (as there may be several such relationships)
• Mapping subresource has a special query whose parameter is a secondary uuid which returns all mappings related to the secondary
• Relationships are created by creating a mapping subresource with the proper secondary reference
• Relationships are deleted by deleting the mapping
• Mapping data is editable
  NOTE: There can only be one collection of mappings or counterparty objects because of caching issues.

• Object as primary contains a createable, uneditable collection of child mappings
• Mapping contains a uneditable reference to object as primary
• Mapping contains a createable, potentially editable reference to object as secondary (whether relationships can be updated is an open question)
• Object does not contain a reference to object as primary or mapping
• Primary resource has a special query whose parameter is a secondary uuid which returns all primaries related to the secondary; this query is identified by the name of the secondary (as there may be several such relationships)
• Mapping subresource has a special query whose parameter is a secondary uuid which returns all mappings related to the secondary
• Relationships are created by creating a mapping subresource with the proper object as secondary reference
• Whether relationships can be edited or merely create and deleted is an open question
• Relationships are deleted by deleting the mapping
• Mapping data is editable
  NOTE: There can only be one collection of mappings or counterparty objects because of caching issues.

Example: Location : LocationTagMap : LocationTag

Model: Primary is a resource; Mapping is a sub-resource of Primary; Secondary is a resource

• Primary contains a createable, uneditable collection of secondaries
• Mapping contains an uneditable reference to primary
• Mapping contains a creatable, non-editable reference to secondary
• Secondary does not contain a reference to primary or mapping
• Primary resource has a special query whose parameter is a secondary uuid which returns all primaries related to the secondary; this query is identified by the name of the secondary (as there may be several such relationships)
• Relationships are created by creating a mapping subresource with the proper secondary reference
• Relationships are deleted by deleting the mapping
  NOTE: The direction in which the relationship is broken is arbitrary, but there can only be one collection of counterparty objects because of caching issues.
