Using LDAP

One may either

• create a LDIF file (e.g.):

    version: 1       
    dn: dcmPDQServiceID=Test HL7 PDQ,dicomDeviceName=dcm4chee-arc,cn=Devices,cn=DICOM Configuration,dc=dcm4che,dc=org
    objectClass: dcmPDQService
    dcmPDQServiceID: Test HL7 PDQ
    dcmURI: pdq-hl7:HL7SND/DCM4CHEE:HL7RCV/DCM4CHEE
    dicomDescription: Test PDQ with External Patient Demographics Supplier
    dcmProperty: XSLStylesheetURI=${jboss.server.temp.url}/dcm4chee-arc/hl7-adt2dcm.xsl
    -
  

and import it to the LDAP Server by using the ldapadd command line utility or the LDIF Import... function of Apache Directory Studio

• or directly use the New Entry... function to create corresponding Exporter entries.

One may refer to PDQ Service to understand the description of attributes.

Go to the Control tab on Configuration page in archive UI and reload the configuration.
