I'm currently building an application that leverages FHIR via the HAPI-FHIR api. Up till now I've been going through the sandboxes listed at hl7.org fhir sandboxes but I have found most of them to have a lot of incomplete/corrupt data. Can anyone recommend a more useful data test of fhir data? The best I have found thus far is the sample data provided by hl7.org but it is still very limited (12 patients, 3 medications).
Thanks for any assistance.
