Creating sample data with GraphBuilder

One of the things I find myself doing quite often is helping people design FHIR API interfaces. Of course, the actual API itself is defined by the FHIR standard – but the parts that are implemented by any given system will vary tremendously – particularly with regard to API features like chaining, reverse chaining and the _include search parameter.

What I find very useful is to create a small set of sample data and save to a generic FHIR server (I use the HAPI server generally, though there are others available these days). Then, I can test out the API calls against that sample data set to make sure I have the syntax right – and they are returning the results I expect.
