GitHub Action for building schemas

This action provides a "one-click" method for preparing JSON schemas for use in an ArtifactDB instance.

• It resolves $ref statements by merging together properties from all referenced subschemas. This produces a schema that has a single properties, which is easier to parse by both humans and machines. The centralization of properties also allows us to set additionalProperties: false, which allows for stricter validation. (This would not be possible if properties are fragmented into different allOf subschemas.
• It validates the schemas against the JSON schema specification using the jsonschema package. We currently use draft 7 of the specification.
• It converts the schemas into human-readable webpages using the json-schema-for-humans packge. It also creates an index page in preparation for publication to GitHub Pages.

To use, simply add the following step to your GitHub Actions workflow:

    - name: Build schemas
      uses: ArtifactDB/[email protected]
      with:
        title: 'My schema overview'

The following optional arguments can be specified:

Option	Default	Description

do_validate	true	Whether to validate the resolved schemas.
do_prettify	true	Whether to prettify the resolved schemas.
path_raw	raw	Path to the input directory containing the raw schemas. Only used if do_resolve = true.
path_resolved	resolved	Path to the directory containing the resolved schemas. This is an output directory if do_resolve = true, otherwise it is an input directory that already contains resolved schemas.
path_docs	public	Path to the output directory containing the human-readable schemas. Only used if do_prettify = true.
docs_title	Schema overview	Title for the landing page. Only required do_prettify = true.
path_tarball		Path to an output tarball containing all resolved schemas. If this is empty, no tarball is created.
