This Python library contains KUDAF metadata schema definitions and logic that is common and applicable to other KUDAF Python packages
Project description
KUDAF Metadata Library
This package contains the following elements:
-
Metadata schema definitions for the Kudaf platform, adhering to global standards: a. DCAT-AP-NO standard: Catalog and Dataset metadata, compatible with the requirements of the Norwegian Fellesdatakatalog b. RAIRD standard: Variable metadata
-
A CLI tool to generate KUDAF Metadata.
It was developed by Sikt - Kunnskapssektorens tjenesteleverandør under the KUDAF initiative to enable a Data Producer to make small-file data available on the KUDAF data-sharing platform.
The CLI can create Catalog, Dataset and Variable-level metadata for the Kudaf data-sharing platform.
About KUDAF

Kudaflib CLI operation
Navigate to the project directory and activate the virtual environment (only if not already activated):
$ source .venv/bin/activate
The kudaf-generate
command should be now activated. This is the main entry point to the CLI's functionalities.
Displaying the help menus
$ kudaf-generate --help
Usage: kudaf-generate [OPTIONS] COMMAND [ARGS]...
Kudaf Metadata Tools
╭─ Options ────────────────────────────────────────────────────────────────────────────────────────────────────────╮

As we can see, there is one sub-command available: metadata
.
We can obtain help on it as well:
$ kudaf-generate metadata --help
Usage: kudaf-generate metadata [OPTIONS]
Generate Variables/UnitTypes Metadata
JSON metadata files ('variables.json' and maybe 'unit_types.json') will be written to the
(optionally) given output directory.
If any of the optional directories is not specified, the current directory is used as default.
╭─ Options ────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ --config-yaml-path PATH Absolute path to the YAML configuration file │
│ [default: /home/me/current/directory/config.yaml] │
│ --output-metadata-dir PATH Absolute path to directory where the Metadata files are to be written to │
│ [default: /home/me/current/directory] │
│ --help Show this message and exit. │
╰──────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
Generating metadata only from a YAML configuration file
$ kudaf-generate metadata --config-yaml-path /home/me/path/to/config.yaml --output-metadata-dir /home/me/path/to/metadata/folder
Developers
Download the package to your computer
Option A: Installation from repository:
Open up a Terminal window and clone the repo locally:
$ git clone https://gitlab.sikt.no/kudaf/kudaflib.git
Option B: Installation from source:
-
Open up your browser and navigate to the project's GitLab page:
https://gitlab.sikt.no/kudaf/kudaflib
-
Once there, download a ZIP file with the source code
-
Move the zipped file to whichever directory you want to use for this installation
-
Open a Terminal window and navigate to the directory where the zipped file is
-
Unzip the downloaded file, it will create a folder called
kudaflib-main
-
Switch to the newly created folder
$ cd path/to/kudaflib-main
Make sure Python3 is installed on your computer (versions from 3.8 up to 3.11 should work fine)
$ python3 --version
Install Poetry (Python package and dependency manager) on your computer
Full Poetry documentation can be found here: https://python-poetry.org/docs/
The official installer should work fine on the command line for Linux, macOS and Windows:
$ curl -sSL https://install.python-poetry.org | python3 -
If the installation was successful, configure this option:
$ poetry config virtualenvs.in-project true
Mac users: Troubleshooting
In case of errors installing Poetry on your Mac, you may have to try installing it with pipx
. But to install that, we need to have Homebrew
installed first.
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
(Homebrew documentation: https://brew.sh/)
Once Homebrew
is installed, proceed to install pipx
:
$ brew install pipx
$ pipx ensurepath
Finally, install Poetry
:
$ pipx install poetry
Create a Python virtual environment and activate it
$ python3 -m venv .venv
This created the virtualenv under the hidden folder .venv
Activate it with:
$ source .venv/bin/activate
Install Kudaf Datasource Tools and other required Python packages
$ poetry install
