add YAML support
- fhir.resources version: latest
- Python version: 3.6+
- Operating System: MAC/Windows/Linux
Description
would like to add native YAML support so that a Resource object can be created from YAML object or file and serialize as a YAML string.
e.g:
>>> from fhir.resources.organization import Organization
>>> from fhir.resources.address import Address
>>> yaml_str = '''
resourceType: Organization
id: f001
active: true
name: Acme Corporation
address:
- country: Swizterland
'''
>>> org = Organization.parse_raw(yaml_str)
>>> isinstance(org.address[0], Address)
>>> True
>>> org.address[0].country == "Swizterland"
True
>>> org.dict()['active'] is True
True
and
>>> from fhir.resources.patient import Patient
>>> import os
>>> import pathlib
>>> filename = pathlib.Path("foo/bar.yaml")
>>> pat = Patient.parse_file(filename)
>>> pat.resource_type == "Patient"
True
and
>>> pat.as_yaml()
'''
resourceType: Organization
id: f001
active: true
name: Acme Corporation
address:
- country: Swizterland
'''
See pyyaml.org
This seems is a very good idea 💡 and also I think this will open up to support for XML. For me, I could try after the holiday season ends (after the new year) but anyone welcomes to try now. Related pydantic issues

@Healthedata1 what should be the proper mime type for YAML? some folk suggest text/yml` or `application/x-yaml` https://stackoverflow.com/questions/332129/yaml-media-type I don't find any definition inside python's built-in module mimetypes``
I don't have an opinion. It seems from the pydantic CRs that just using the yaml dump and load methods is the preferred choice.
e.g.
Testing out fhir.resources
start with fhirstring class...
from fhir.resources.patient import Patient as P
from yaml import dump as y_dump, load as y_load
import datetime
p = P()
p.json()
'{"resourceType": "Patient"}'
print(y_dump(p.dict()))
resourceType: Patient

not yet, but I will. I am going through the FastAPI spec hoping to generate swagger docs using the models but I see that there are some issues with that.
