OLE Instance Document-V9.1

1. Description

The OLE Instance document is a container for recording holdings and item information for a bibliographic record. Even though there is a standard for MARC Holdings (which has often been loosely followed), there isn't one for items and depending on the vendor systems, these are stored in different ways. OLE Instance defines a standard for storing holdings/item information in three main sections as described below.

2. Main Sections of the OLE Instance Document

1. oleHoldings: This section records "general" holdings information in a format specific to OLE.
2. sourceHoldings: This section represents "specific" holdings information entered according to some standard external to OLE. Examples are MARC holdings, MODS holdings or any other format specific holdings.
3. items: This section records information about 1 or more items.

   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.  If an OLE Instance is initially created using oleHoldings, a staff user will be able to click a button in order to convert the oleHoldings to sourceHoldings via a mapping from one to the other.
