  1. Setting up the environment

    • Precondition: Visual Studio or IntelliJ IDEA or Eclipse have been installed
    • Action (.Net): create a new .Net solution and add the Hl7.Fhir.DSTU2 package with NuGet
    • Action (Java): create a new Java application and add HAPI through Maven

  2. Start using the API

    • Precondition: the NuGet or Maven package has been added to the project
    • Action (.Net): add lines to your project code to use Hl7.Fhir.Model and Hl7.Fhir.Rest and create a new FHIR client that points to one of the publically available test servers
    • Action (Java): add lines to your project code to import ca.uhn.fhir.context.FhirContext and ca.uhn.fhir.rest.client.IGenericClient and create a new FHIR client that points to one of the publically available test servers
    • Bonus point: error handling has been set up

  3. Retrieve a single Resource

    • Action: read a single Resource from the server with id “example”, e.g. an Observation, and display the text part
    • Bonus: The UI displays an error message when the Resource does not exist

  4. Create a Resource

    • Action: Create a Patient model object instance and populate it with a name and identifier
    • Action: Use the .NET/Java client to upload this resource to a test server
    • Action: Print the ID of the newly created resource

  5. Update a Resource

    • Action: Edit the Patient resource from the previous task by adding more information
    • Action: Use the .Net/Java client to update this resource on the test server
    • Bonus: Have the UI show the version of the resource

  6. Search for a specific Resource type

    • Action: search the server for all Resources of a specific type, e.g. Observation, and display the id for each Resource
    • Bonus: limit the number of results to 5
    • Bonus 2: The UI allows the user to display the next page of search results

  7. Search for specific Resource instances

    • Action: search the server for specific Resource instances, e.g. all Patients with the name Steve
    • Tip: look at the Resource page in the specification; at the bottom of each page you'll find a list of all search parameters for that Resource type
    • Display the id for each matching resource, plus the value that matched your search parameter, e.g. the name

  8. Make a transaction

    • Action: build a transaction Bundle
    • Action: Add at least two transactions to the Bundle, for example one create interaction and one read interaction.
    • Action: Send the transaction to a test server
    • Bonus: Display the results of the transaction

  9. Bonus: Extra assignments

    • If you've implemented all of the previous assignments, try other interactions from the FHIR REST specification
    • Look at the search page in the specification and try to perform more specific searches, such as all retrieving all Encounters of Patients with the name John, or including another Resource type
