fhir-core 0.1.0b9

FHIR Core library

FHIR® Core

Powered by Pydantic V2. This library is developed for the support of the another libray fhir.resources but you are more than welcome to use it for your own purpose. It provides an abstract base class for any FHIR resource model and Primitive Datatypes along with factories to create FHIR resource model and other complex datatypes.

Installation

Just a simple pip install fhir-core. But if you want development version, just clone from https://github.com/nazrulworld/fhir-core and pip install -e .[dev].

Usages

Example: 1: This example creates an Organization class with some of its attributes (id, active, name, address):

>>> from typing import List
>>> from pydantic import Field
>>> from fhir_core.fhirabstractmodel import FHIRAbstractModel
>>> from fhir_core.types import IdType, BooleanType, StringType
>>> data = {
...     "id": "f001",
...     "active": True,
...     "name": "Acme Corporation",
...     "address": ["Road 10": "Acme corporation", "2390", "USA"}]
... }
>>> class Organization(FHIRAbstractModel):
...     __resource_type__ = "Organization"
...     id: IdType = Field(None, title="Id", alias="id", json_schema_extra={"element_property": True})
...     active: BooleanType = Field(None, title="Active", alias="active", json_schema_extra={"element_property": True})
...     name: StringType = Field(None, title="Name", alias="name", json_schema_extra={"element_property": True})
...     address: ListType[StringType] = Field(None, title="Address lines", alias="address", json_schema_extra={"element_property": True})
...
...     @classmethod
        def elements_sequence(cls):
            return ["id", "active", "name", "address"]
...
>>> org = Organization.model_validate(data)
>>> org.active is True
True
>>> org_json_str = org.model_dump_json()
>>> Organization.model_validate_json(org_json_str).model_dump() == org.model_dump()
True
