Python representation of FHIR® specification. Idea and class structure based on



A class that is controlling the behavior of fhirspec.FHIRSpec, powerful but very convenient. In several ways it is possible to construct the instance, ie. from JSON file (has support for json5), from python module, from TOML file, from plain text file, and so on. Only capital letter’s variables are accepted

>>> import pathlib
>>> import os
>>> from foo.module import bar
>>> from fhirspec import Configuration
>>> config1 = Configuration.from_module(bar)
>>> config2 = Configuration.from_json_file(pathlib.Path("/json/file/location"))
>>> data_dict = {
... "BASE_URL": pathlib.Path(os.path.abspath(__file__))
... }
>>> config3 = Configuration(data_dict=data_dict)


The main loader class, to construct this instance, Configuration: is required parameter and additionally source of json files. Bellows variables should have to be present in configuration.

required_variables = [


>>> from fhirspec import Configuration
>>> from fhirspec import FHIRSpec
>>> config = Configuration(
... {
...   "BASE_PATH": "",
... }
... )
>>> spec = FHIRSpec(config)
>>> "patient" in spec.profiles


A perfect tool to download any file from server, no dependency on third-party library.

>>> from fhirspec import download
>>> url = ""
>>> download_directory = pathlib.Path(os.path.expanduser("~/Downloads"))
>>> download(url, download_directory)
>>> (download_directory / "sample.pdf").exists()
