7. Project / Source Layout 7

8. Source Code Directory Structure DIRECTORYDESCRIPTION C:\projects\NHINC\Current\Product Contains master ant script that compiles the CONNECT gateway and adapter C:\projects\NHINC\Current\Product\Production This project will contain sub folders that separate the code by its primary location (i.e. Common, Gateway, Adapter) C:\projects\NHINC\Current\Product\Production\AdapterCONNECT adapter source C:\projects\NHINC\Current\Product\Production\Common Source used by both gateway and adapter C:\projects\NHINC\Current\Product\Production\GatewayCONNECT gateway source C:\projects\NHINC\Current\ThirdParty Contains third party libraries needed to compile 8

10. Project Creation Guidelines »WIKI page describes the projects –http://developer.connectopensource.org/display/CONNECTWIKI/Proje ct+Creation+Guidelineshttp://developer.connectopensource.org/display/CONNECTWIKI/Proje ct+Creation+Guidelines 10

11. Special Projects PROJECT/DIRECTORYPURPOSE Common\Interfaces Contains all of the WSDL and schemas that are being used within CONNECT Common\Properties Contains property files and configuration files that are used within CONNECT (These are used in: C:\Sun\AppServer\Domains\Domain1\Config and C:\Sun\AppServer\Domains\Domain1\Config\N hin 11

12. Web Service WSDL File Naming Conventions 12 »First part identifies the type of service –Adapter: Services on the adapter –Entity: Services on the gateway which are called by the adapter –Nhinc: Services on the gateway that are internal to the gateway –Nhin: NHIN services hosted or called by the CONNECT gateway »If “component” identified in second part… –NhincComponent: Identifies internal components to the gateway –AdapterComponent: Identifies services on the Adapter Service Bus Used to customize an adapter service –EntityComponent: Identifies gateway internal services which orchestrate a message »Adapter/Entity interfaces may contain word Secured/Unsecured –Identifies whether the interface represents the secured or unsecured interface »Rest of the name identifies the service »Example –AdapterComponentSecuredMPI.wsdl

13. XML Schema Layout and Naming Conventions »Directory: Interfaces\src\schemas »First level of hierarchy: identifies organization or type of schemas »schemas\nhinc: CONNECT schemas »schemas\nhinc\common: used in gateway and adapter »schemas\nhinc\gateway: used in gateway »schemas\nhinc\hl7: schemas to combine HL7 messages 13

14. Connection Manager »Manages endpoint URLs –NHIN services –Replaceable services »Two points of configuration –UDDI UDDI Update Manager service uddiConnectionInfo.xml: CONNECT service information cache –Do not modify this file by hand –Internal Used to override UDDI settings – settings here take precedence over UDDI Used for non UDDI supported services internalConnectionInfo.xml 14

15. Example internalConnectionInfo.xml 1.1 DoD DoD Description subjectdiscovery https://localhost:8181/PIXConsumer_Service/SubjectDiscovery nhincsubjectdiscovery NHIN-CONNECT Internal Subject Discovery http://localhost:9080/NhinConnect/NhincSubjectDiscovery 15
