Common utilities for DFM adapter libraries

nv-dfm-lib-common

Shared schemas and utilities for NVIDIA Data Federation Mesh (DFM) adapter libraries.

What is DFM?

Data Federation Mesh (DFM) is a Python-based framework for creating and orchestrating complex workflows that process data from various distributed sources and stream results into applications. DFM determines where to run each operation of a data processing pipeline and handles data movement between sites automatically.

Overview

nv-dfm-lib-common provides common building blocks used across DFM adapter libraries such as nv-dfm-lib-weather:

Component	Description
Output Schemas	Pydantic models for adapter return types: GeoJsonFile, TextureFile, TextureFileList
XArray Schemas	Schema definitions and validation for xarray Datasets (XArraySchema, coordinate/variable checks)

This package is part of the DFM ecosystem:

Package	Description
nv-dfm-core	Core framework — Pipeline API, execution engine, code generation, and CLI
nv-dfm-lib-weather	Experimental weather and climate data adapters (GFS, ECMWF, HRRR, SFNO, cBottle)

Installation

This package is typically installed as a dependency of other nv-dfm-lib-* packages:

pip install nv-dfm-lib-common

Or from source with uv:

git clone https://github.com/NVIDIA/data-federation-mesh.git
cd data-federation-mesh
uv sync --package nv-dfm-lib-common

Usage

from nv_dfm_lib_common.schemas import GeoJsonFile, TextureFile, TextureFileList
from nv_dfm_lib_common.schemas.xarray import XArraySchema, check_dims, check_dtype
