Process Data Transfer Start v0.3.1

Jump to bottom
Reto Wettstein edited this page Nov 16, 2022 · 10 revisions

This page lists FHIR resources that can be used to prepare a DIC KDS FHIR store and start the data-transfer send process at a DIC. The following needs to be known beforehand:

  • The DIC identifier of the local organization
  • The COS identifier which should receive the project results
  • A project identifier for which results should be transmitted
  • The project results (i.e. the actual data) that should be transmitted

It is important to differentiate between the DSF FHIR server and the KDS FHIR store. The DSF FHIR server contains all FHIR resources of the DSF needed for process flow and the KDS FHIR store contains the project results (i.e. the actual data) to be transmitted. These are two different FHIR servers.

DIC: Prepare KDS FHIR Store

The DIC KDS FHIR store needs to be prepared with the data-set that should be transmitted to the COS.

Caution: The following steps for DIC KDS FHIR Store preparation can be omitted if you are using the provided script for data extraction, pseudonymization and data-set upload.

To prepare your DIC KDS FHIR store manually, upload a Transaction Bundle like the following examples containing a DocumentReference resource and a linked Binary or Bundle as attachment resource. Please replace all placeholders in the form <REPLACE-WITH-...>.

To send the Transaction Bundle to a KDS FHIR store with basic authentication, the following cURL command could be used:

curl \
-u "<username>:<password>" \ 
-H "Accept: application/fhir+xml" -H "Content-Type: application/fhir+xml" \
-d @transaction-bundle.xml \
https://<kds-fhir-base-url>/fhir

Notice: On Windows you need to remove the \ multi-line command seperators.

The individual parts of the command have the following meaning:

  • <username> represents the basic authentication username
  • <password> represents the basic authentication password
  • transaction-bundle.xml contains the corresponding Transaction Bundle resource from below
  • <kds-fhir-base-url> needs to be replaced with the base url of your KDS FHIR store

Notice 2: This works only if you are using a HAPI FHIR server as your DIC KDS FHIR store having set the environment variable HAPI_FHIR_ALLOWED_BUNDLE_TYPES: COLLECTION,DOCUMENT,MESSAGE,TRANSACTION,TRANSACTIONRESPONSE,BATCH,BATCHRESPONSE,HISTORY,SEARCHSET. If you are using a BLAZE FHIR server as your DIC KDS FHIR store, you have to upload and link both resources separately. Start by uploading the attachment resource, add the id of the attachment resource to DocumentReference.content.attachment.url and upload the DocumentReference resource.

DIC: Start Send Process

To start the data-transfer send process, a Task resource like the following example has to be sent to the DIC DSF FHIR server. Please replace all placeholders in the form <REPLACE-WITH-...>.

To send the Task resource to the DIC DSF FHIR server, the following cURL command could be used:

curl \
--cert client-certificate.pem \
--key client-certificate_private-key.pem \
-H "Accept: application/fhir+xml" -H "Content-Type: application/fhir+xml" \
-d @task.xml \
https://<dsf-fhir-base-url>/fhir/Task

Notice: On Windows you need to remove the \ multi-line command seperators.

The individual parts of the command have the following meaning:

  • task.xml contains the corresponding Task resource from below
  • client-certificate.pem contains your client-certificate
  • client-certificate_private-key.pem contains the private-key belonging to your client-certificate
  • <dsf-fhir-base-url> needs to be replaced with the base url of your DSF FHIR server
