Bulk Load: XML or spreadsheet (tab-delimited text) file that supplier creates and buyer uploads using the eContent Manager.
You can use either extraction or bulk loading, or both methods, to maintain buyer-hosted content. For example, bulk-loaded items can augment items already extracted into the iProcurement catalog.

• You can bulk load items in addition to items you’ve extracted.
• You can modify extracted items using your bulk load file. Basically, bulk loading lets you specify more information about items than the item master or other sources may allow.

The Oracle iProcurement catalog supports the bulk loading of catalog data. Catalog data consists of the items and services available for purchase as well as the associated prices for these goods.
Catalog data may have originated from any of the following sources:
■ Downloaded from an Oracle Exchange marketplace, such as Exchange.Oracle.com.
■ Obtained directly from a supplier.
■ Obtained from a third-party catalog provider.
■ Created internally.

The bulk loader supports item catalogs created in the following formats:
■ Tab-delimited text file (spreadsheet)
■ XML
■ Catalog Interchange Format (CIF)
■ cXML (commerce eXtensible Markup Language, which is based on the XML language)

The catalog bulk loader also supports the creation of catalog schema using XML files. The catalog schema consists of a combination of categories, local descriptors used to describe items in a specific category, and base descriptors used to describe any item or service in the catalog.
