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
