Validator and examples for openPMD format

Project description

# openPMD Validator Scripts

[![Build Status 1.1.X](](
![Supported Python Versions](

This repository contains scripts to validate existing files that (claim to)
implement the [openPMD Standard](
in version `1.1.*`.

Additional scripts to create random/empty files with the valid markup of the
standard are also provided.

## Rationale

These tools are intended for developers that want to implementent the standard.
They were written to allow an easy *implement-test-correct* workflow without
the hazzle to check every word of the written standard twice.

Nevertheless, these scripts can not validate 100% of the standard and uncovered
sections shall be cross-checked manually with the words of the written

For more information on requirements for implementations, please refer to the
of the openPMD standard. The repository
also lists a large collection of open source projects that already implement
the openPMD standard.

## Install

[![pypi version](](
[![Spack Package](](
[![Conda Package](](

Choose *one* of the install methods below to get started:

### PyPI

# optional: append --user
pip install openPMD-validator==

### Spack

spack install py-openpmd-validator@ ^py-h5py~mpi
spack load --dependencies py-openpmd-validator@ ^py-h5py~mpi

### Conda

conda install -c ax3l openpmd_validator==

### From Source

tar -xf
cd openPMD-validator-

# optional: append --user
python install

## Usage

### CLI

We provide the command-line tools for individual files:

# optional: create dummy example files

# validate
openPMD_check_h5 -i example.h5
# optional: append --EDPIC for the Partice-in-Cell Extension

### Module

Additionally, the validator tools can be used as *Python module* in your projects, e.g. to verify a file before opening it for reading.

from openpmd_validator import createExamples_h5

# create "example.h5"

from openpmd_validator import check_h5

result_array = check_h5.check_file("example.h5", verbose=False)

print("Result: %d Errors and %d Warnings."
%( result_array[0], result_array[1]))

## Development

The development of these scripts is carried out *per-branch*.
Each branch corresponds to a certain version of the standard and might
be updated in case tests did contain bugs or we found a way to cover more
sections of the standard.
