|
| The proposed Cross-Enterprise Service Bus (XSB) profile is intended to meet the need for a message-based layer or framework, compatible with Web Services, that is constrained to meet the interoperability requirements of healthcare documents/messages in transit and that facilitates basic document/message integrity and confidentiality, security/privacy auditing and invocation of access control services.
| |
|
| |
|
| ==3. Key Use Case== | | ==3. Key Use Case== |
|
| |
| The XSB profile would allow the large class of healthcare use cases that require message-based transport of documents/messages to be implemented with much of the required security and privacy functionality provided by implicit service invocations during transport layer processing.

| The proposed XSB profile could be considered a message-based extension or supplement to the connection-based ATNA profile. It also supplements and provides additional context for XUA.
| |
| The HL7-SOA Privacy, Access and Security Services (PASS)-Functional Models are scheduled for ballot January, 2008. The IHE XSB profile would provide the constrained, real world technical specification anticipated in the illustrative Web Service-based use cases provided in the PASS functional specification.
| |
| An XSB is not an Enterprise Service Bus nor is it an SOA implementation.
