### 6.4.3 WS - RetrieveImagingDocumentSetMetadataRequest

#### 6.4.3.1 Request

The specific Web Services parameters to be used for the Retrieve Imaging Document Set Metadata action shall be as follows, in the order that they would appear in the WSDL definition:

- The following types shall be imported (xsd:import) in the /definitions/types section:

  - namespace="urn:ihe:rad:xdsi-b:2009", schema="XDSI.b_ImagingDocumentSource.xsd"

  - The baseline XDS.b schema (namespace="urn:ihe:iti:xds-b:2007", schema="XDS.b_DocumentRepository.xsd")

  - The baseline DICOM WADO-WS schema (namespace="urn:dicom:wado:ws:2011", schema="dicom.wado.ws.2011.xsd")

- The /definitions/message/part/@element attribute of the Retrieve Imaging Document Information Set Request message shall be defined an "wado:RetrieveImagingDocumentSetInformationRequest" as defined below.

- The /definitions/message/part/@element attribute of the Retrieve Imaging Document Set Information Response message shall be defined an "wado:RetrieveImagingDocumentSetInformationResponse" as defined below.

- The /definitions/portType/operation/input/@wsaw:Action attribute for the Retrieve Imaging Document Set Information Request message shall be "urn:wado:2011:RetrieveImagingDocumentSetInformation".

- The /definitions/portType/operation/output/@wsaw:Action attribute for the Retrieve Imaging Document Set Information Response message shall be "urn:wado:2011:RetrieveImagingDocumentSetInformationResponse".

- The /definitions/binding/operation/soap12:operation/@soapAction attribute shall be "urn:wado:2011:RetrieveImagingDocumentSetInformation".

The <wado:RetrieveImagingDocumentSetInformationRequest/> element for use with the Retrieve Imaging Document Set Request Message is defined as:

- One or more <wado:StudyRequest/> elements each of which includes a "studyInstanceUID" attribute identifying the study associated with the DICOM images/objects being retrieved. Each <iherad:StudyRequest/> element shall contain:

  - One or more <wado:SeriesRequest/> elements each of which includes a "seriesInstanceUID" attribute identifying the series associated with the DICOM images/objects being retrieved. Each <iherad:SeriesRequest/> element shall contain:

    - One or more <wado:DocumentInformationRequest/> elements, each one representing an individual document that the requestor wants to retrieve from the Web Server. Each < wado:DocumentInformationRequest /> element contains:

      - · An required <ihe:RepositoryUniqueId/> element that identifies the Web Server from which the document is to be retrieved. This value corresponds to XDSDocumentEntry.repositoryUniqueId. The RepositoryUniqueID is similar to a DICOM AE Title, but is a uniqueID assigned to the WADO-WS Web Server rather than a locally assigned string identifier. There will be a separate RepositoryUniqueID for each web service end point.

      - A required <ihe:DocumentUniqueId/> element that identifies the document within the source. For example, this value could be a SOP Instance UID obtained from a Key Object Selection (KOS) instance.

      - An optional <ihe:HomeCommunityId/> element. See the IHE Profiles for the definition and possible uses of this element.

      - An optional <wado:Anonymize/> element

      - A required <wado:XPath/> that contains the text corresponding to the XPath "filter" applied to the Native DICOM Model transposition of the object, as defined in PS3.19.

        ### Note

        If the requested filter is "/", then all of the metadata is requested.
