Enterprises are looking for commercial vendors to offer capabilities to enable the trustworthy sharing of information across organizational and security boundaries. A key trust concern in an information sharing environment, a supply chain, or any value chain is the provenance of the information, software, service, or product; and, the reputation of the provider. The purpose of the workshop is to identify the key issues and concerns of customers regarding provenance and reputation management systems, and to identify priority actions to address these concerns.
