1 Cross-Enterprise Document Sharing-b (XDS.b) Slides prepared by Roberto Ruggeri, XDS.b Slides Presented by Vassil Peytchev, PIX/PDQ v3, Appendix V

2 Introduction XDS.b is an evolution of the current XDS Integration Profile (XDS.a) Same business scenario as XDS.a Provides new transactions in line with current standards XDS.a and XDS.b can co-exist 2

3 Whats new in XDS.b Document metadata format is ebXML Registry Information Model, Version 3.0 –Added new repositoryUniqueId attribute New Retrieve Document Set transaction with Web Services binding New transactions with updated Web Services bindings WSDL for Document Repository, Document Registry Allows for either Patient Identity Feed HL7v2 or HL7v3 or both to accommodate different scenarios –E.g.: Canada focusing on HL7 v3, U.S. focusing on HL7 v2 No support for off-line mode 3

4 What is the Same in XDS.b Addresses same scenario as XDS.a providing new implementation mechanism Maintains the same options as XDS.a –Multiple document submission –Document Lifecycle management –Folder management Composes with other IHE content profiles 4

5 Document Metadata Changes New repositoryUniqueId allows for proper identification of location where document is stored –Document Consumers binds to appropriate repository Document URI becomes optional –If present indicates support for Retrieve Document transaction [ITI 17] 5

6 Coexistence and Migration XDS.b allows the document URI metadata attribute to be present –Facilitates the use of XDS.b Document Repository/Registry in legacy XDS.a environments XDS.b identifies rules for implementations claiming conformance against both XDS.a and XDS.b at the same time [ITI TF-1:10.7] in the supplement explains common scenarios 6

7 XDS.b Actors and Transactions Document Registry –Registry Stored Query [ITI-18] –Register Document Set-b –Patient Identity Feed (HL7v2/HL7v3) Document Repository –Provide and Register Document Set-b –Retrieve Document Set 7

8 XDS.b Actors and Transactions Patient Identity Source Document Registry Document Consumer Document Repository Document Source Patient Identity Feed [ITI-8] Patient Identity Feed HL7v3 Registry Stored Query [ITI-18] Register Document Set-b Retrieve Document Set Provide and Register Document Set-b Integrated Document Source/Repository 8

9 Changes in Actor Behavior Document Repository populates repositoryUniqueId before calling Register Document Set-b Document Registry can support either Patient Identity Feed HL7v2 or HL7v3 or both to accommodate different scenarios and requirement Document Consumer needs to resolve the Document Repository endpoint before invoking the Retrieve Document Set transaction –Enables use of proxies for multiple Document Repositories 9

10 XDS.b Transactions All transactions reference ebXML Registry Information Model 3.0 All transactions support SOAP 1.2 –Optionally support SOAP 1.1 All transactions support WS- Addressing All transactions have WSDL defined –Appendix V: one WSDL per Actor per Integration Profile 10

11 Changes in Transactions New XML schema types are defined –Provide and Register Document Set-b Request –Retrieve Document Set Request/Response Document content is within the s:Body in an element of type xs:base64Binary for MTOM support 11

12 12 Provide and Register Document Set-b Request Enables support for MTOM Same document metadata as XDS.a Links the document to its metadata

13 13 Retrieve Document Set Request Support for Cross Community Access (XCA) Retrieve any number of documents Enables Consumer to bind to actual Web Service

14 14 Retrieve Document Set Response Error messages consistent with ebRS 3.0 Retrieve any number of documents Links to Registry Response

18 Retrieve Document Set Request Sample 18 urn:ihe:iti:2007:RetrieveDocumentSet urn:uuid:80b0b9c6-e bae5-7fcf994a9f25 Support for WS- Addressing Synchronous request

19 Retrieve Document Set Response 19 urn:ihe:iti:2007:RetrieveDocumentSetResponse urn:uuid:80b0b9c6-e bae5-7fcf994a9f25 Use of appropriate WSA action Indicates reply to previous message

20 Tips and Tricks When generating Web Services proxy/stubs, evaluate using a development WSDL –Replaces typed definitions with un-typed XML MTOM gives you binary attachments for free –Supports composition with WS-Security, WS-Reliable Messaging 20

21 Sample C# Code 21 [ServiceContract( Namespace = "urn:ihe:iti:xds-b:2007", Name = "XDSRepository")] public interface IXdsDocumentRepository { [OperationContract( Action = "urn:ihe:iti:2007:ProvideAndRegisterDocumentSet-b", ReplyAction = "urn:ihe:iti:2007:ProvideAndRegisterDocumentSet-bResponse")] Message ProvideAndRegisterDocumentSet(Message input); [OperationContract( Action = "urn:ihe:iti:2007:RetrieveDocumentSet", ReplyAction = "urn:ihe:iti:2007:RetrieveDocumentSetResponse")] Message RetrieveDocumentSet(Message input); } Use appropriate namespace and WSDL name Define WS-Addressing Actions for both Request and Response Evaluate use of un- typed development WSDL

22 Whats Next for XDS.b Cross Community Access (XCA) composes with XDS.b Cross-Enterprise User Assertion (XUA) composes with XDS.b via WS- Security
