GitHub Action to apply pylode for publishing github-managed ontologies via github pages

This action is to be used on git projects that maintain described ontology-files in ttl. It applies pyLODE to convert a human readable html version of them to be published via github pages.

The generated html is placed inside the actual repository folder ./ using this procedure:

• It simply runs through all folders and files and looks for **/name.ttl files.
• For all found entries it
  • creates a backup **/name.ttl.bak file
  • uses jinja2 to pre-process those to inject the provided {{ baseuri }} and {{ name }} parameters to update the **/name.ttl file
  • using pyLODE it produces an html file called **/name from the contents of the ttl
  • and finally adds an entry for it in the ./index.html at the root

The jinja2 pre-processing allows to have specific values to be injected:

Below is an example yaml file that once copied to /.github/workflow/pylode_to_pages.yml will trigger the publishing to github pages action on push to the "main" branch.

name: PyLODE to GitHub Pages
on:
  push:
    branches:
      - main  # Set a branch name to trigger deployment
  pull_request:
jobs:
  pylode-to-pages:
    runs-on: ubuntu-20.04
    concurrency:
      group: ${{ github.workflow }}-${{ github.ref }}
    steps:
      - uses: actions/checkout@v2
        with:
          submodules: true  # Fetch Hugo themes (true OR recursive)
          fetch-depth: 0    # Fetch all history for .GitInfo and .Lastmod

      - name: Setup Python
        uses: actions/setup-python@v3
        with:
          python-version: '3.x'

      - name: Build Pages
        uses: vliz-be-opsci/pylode-to-pages@v0
        with:
          baseuri: http://yourdomain.com/NS/

      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        if: ${{ github.ref == 'refs/heads/main' }}
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./

In order to get this thing flying one needs to run these steps as an admin user on the github-project holding the ontologies to publish.

git checkout gh-pages
git push origin --delete gh-pages
git push origin
git checkout main
