- oleHoldings: This section records general holdings information when there may not be a specific holdings format like MARC holdings or for serials like books where there won't be one.
- sourceHoldings: This section represents specific holdings information in the native format. Examples are MARC holdings, MODS holdings or any other format specific holdings.
- items: This section records information about 1 or more items.
Info For a given bibliographic record, only one of either oleHoldings or sourceHoldings can be used as the main holdings record. OLE will not support usage of both for a given record as that leads to overhead of managing data consistencies between the two sections.
