Description
During 1.5, the structure of the OLE Instance had been changed. The wrapper that was the OLE Instance had been removed. Now there are several separate schemas that hold bibliographic, holdings, electronic holdings, and item data.
A Record has two levels of information: content and metadata.
Content means the actual information of the record.
Document (shown below as recordType-doc-schema) means the content and and the corresponding metadata (like dateCreated, dateUpdated, isStaffOnly etc).
Bibliographic Records:
Holdings:
Electronic Holdings:
Item:
