This repository contains the supplementary information / metadata around site, species and domain details. This is used within the OpenGHG project.

Note that openghg_defs should be installed in the same virtual environment as OpenGHG.

If you feel like you'll want to make changes to the metadata stored you should go for an editable install of the git repository. This will help ensure you always have the latest development changes we make to the repository. It also means that you can make changes to your local copy of the metadata and see the results straight away in your OpenGHG workflow.

First, clone the repository

git clone https://github.com/openghg/openghg_defs.git

Next, move into the repository and use pip to create an editable install using the -e flag.

NOTE: If you're using OpenGHG, please install openghg_defs in the same virtual environment.

cd openghg_defs
pip install -e .

This will create a symbolic link between the folder and your Python environment, meaning any changes you make to the files in the repository folder will be accessible to OpenGHG.

If you don't think you'll need to make any changes to the metadata, you can install openghg_defs from PyPI using pip:

pip install openghg-defs

You can also install openghg_defs from our conda channel:

pip install -c openghg openghg-defs

The path to the overall data path and primary definition JSON files are accessible using:

import openghg_defs

species_info_file = openghg_defs.species_info_file
site_info_file = openghg_defs.site_info_file
domain_info_file = openghg_defs.domain_info_file

We invite users to update the information we have stored. If you find a mistake in the data or want to add something, please open an issue and fill out the template that matches your problem. You're also welcome to submit a pull-request with your fix.

For the recommended development process please see the OpenGHG documentation

After making changes to the package please ensure you've added a test if adding new functionality and run the tests making sure they all pass.

pytest -v tests/

The package is released using GitHub actions and pushed to conda and PyPI.

• Update the changelog to add the header for the new version and add the date.
• Update the Unreleased header to match the version you're releasing and ...HEAD.

For a new release the package version must be updated in the pyproject.toml file. Try and follow the Semantic Versioning method.

Now tag the commit. First we create the tag and add a message (remember to insert correct version numbers here).

git tag -a x.x.x -m "openghg_defs release vx.x.x"

Next push the tag. This will trigger the automated release by GitHub Actions.

git push origin x.x.x

Check the GitHub Actions runners to ensure the tests have all passed and the build for conda and PyPI has run successfully.
