Krama Core

Python-first ABDM/FHIR bundle generation for Indian healthcare products.

Built by Nirvya Labs.

Krama Core helps developers generate ABDM-compliant FHIR R4 document bundles without hand-assembling every resource and reference. It is intentionally small: Pydantic for input validation, plain Python dictionaries for output, and no runtime dependency beyond pydantic.

Installation

pip install krama-core

For local development:

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

Quick Start

import json

from krama.fhir import create_op_consult_bundle
from krama.fhir.bundles import (
    DiagnosisInfo,
    OrganizationInfo,
    PatientInfo,
    PractitionerInfo,
)

bundle = create_op_consult_bundle(
    patient=PatientInfo(
        name="Ravi Kumar",
        abha_address="ravi.kumar@abdm",
        gender="male",
        date_of_birth="1990-05-15",
    ),
    practitioner=PractitionerInfo(
        name="Dr. Priya Sharma",
        identifier="DOC-12345",
    ),
    organization=OrganizationInfo(
        name="District Hospital Guntur",
        hfr_id="IN0410000123",
    ),
    diagnosis=DiagnosisInfo(
        description="Essential hypertension",
        snomed_code="59621000",
        clinical_notes="BP 150/95, prescribed amlodipine 5mg",
    ),
    encounter_date="2026-05-06",
)

print(json.dumps(bundle, indent=2))

Supported Bundles

Krama Core v0.1 supports three ABDM care contexts:

• create_op_consult_bundle() for outpatient consultation records
• create_prescription_bundle() for prescription records
• create_discharge_summary_bundle() for inpatient discharge summaries

Each bundle is returned as a JSON-serializable Python dictionary.

What Krama Handles

• Bundle.type = "document"
• Composition as the first bundle entry
• Internal urn:uuid: references between resources
• Patient, practitioner, organization, encounter, diagnosis, and medication resources
• SNOMED CT coding fields for diagnoses and medications
• Pydantic validation for required inputs and FHIR gender values

Development

Run the checks:

pytest -v
ruff check src/ tests/ examples/
bandit -r src/
pip-audit
python examples/basic_usage.py

Build and validate package artifacts:

python -m build
twine check dist/*

Status

Alpha. The API is small and usable, but still expected to evolve as ABDM integration coverage expands.

Roadmap

• Local mock ABDM gateway for offline development
• Async webhook handler with callback reliability helpers
• Diagnostic Report and Immunization bundle types
• FHIR R4 bundle validator
• FastAPI integration examples

Why "Krama"?

Krama means order, sequence, or method. ABDM integration is a strict sequence of care contexts, callbacks, consent flows, and clinical records. Krama exists to make that sequence easier to build and reason about.
