XCBL

xCBL is a collection of XML specifications for use in e-business. It was created by Commerce One Inc. and is maintained by Perfect Commerce.

History

xCBL was originally called Common Business Library. The xCBL standardization began in 1997.
This led to the creation of xCBL 2.0 which covered 12 different business document specifications, mainly meant for electronic document communication in business-to-business procurement over the Internet. xCBL 2.0 was mainly based on existing Electronic Data Interchange standards and introduced the Schema for [Object-Oriented XML] schema library for XML validation.

Use

As an XML document standard, xCBL is used primarily in B2B procurement tools for buyers, order and invoice management tools for suppliers and document routing tools for public and private marketplaces.
For xCBL message transport, Commerce One created an envelope messaging standard called MML based on the SMTP MIME format to provide both payload and attachment support.
