gks-metaschema

Tools and scripts for parsing the GA4GH Genomic Knowledge Standards (GKS) metaschemas. The metaschema processor (MSP) converts JSON Schema Version 2020-12 in YAML to reStructuredText (RST) and JSON files.

Currently used in:

• GKS-Core
• VRS
• VA-Spec
• Cat-VRS

Installing for development

Prerequisites

• Python 3.12: We recommend using pyenv.

Installation Steps

Fork the repo at https://github.com/ga4gh/gks-metaschema, and initialize a development environment.

git clone [email protected]:YOUR_GITHUB_ID/gks-metaschema.git
cd gks-metaschema
make devready
source venv/3.12/bin/activate

Set up the pre-commit hook

cp ./scripts/pre-commit ./.git/hooks/

Testing

To run the tests:

make test

Usage

File Hierarchy

The metaschema processor expects the following hierarchy:

├── docs
│   ├── source
│   |   ├── ...
│   ├── Makefile
├── schema
│   ├──gks_schema
│   |   ├── gks-schema-source.yaml
│   |   ├── Makefile
│   |   ├── prune.mk
│   ├── Makefile

• docs: Sphinx documentation directory. Must be named docs.
  • source: Directory containing documentation written in reStructuredText and Sphinx configuration. Must be named source.
  • Makefile: Commands to create the reStructuredText files. This file should not change across GKS projects.
• schema: Schema directory. Can also contain submodules for other GKS product schemas.
  • gks_schema: Schema directory for GKS product. The directory name should reflect the product, e.g. vrs.
    • gks-schema-source.yaml: Source document for the JSON Schema 2020-12. The file name should reflect the standard, e.g. vrs-source.yaml. The file name must end with -source.yaml.
    • Makefile: Commands to create the reStructuredText and JSON files. This file should not change across GKS projects.
    • prune.mk: Cleanup of files in def and json directories based on source document. This file should not change across GKS projects.
  • Makefile: Commands to create the reStructuredText and JSON files.

Contributing to the schema

To create the corresponding def (reStructuredText) and json files after making changes to the source document, from the schema directory:

    make all

The file structure will now look like:

├── schema
│   ├──gks_schema
|   |   ├── def
│   |   |   ├── ...
|   |   ├── json
│   |   |   ├── ...
│   |   ├── gks-schema-source.yaml
│   |   ├── Makefile
│   |   ├── prune.mk
│   ├── Makefile

Contributing to the docs

GKS specification documentation is written in reStructuredText and located in docs/source.

To build documentation locally, you must install entr:

brew install entr

Then from the docs directory:

make clean watch &

Then, open docs/build/html/index.html. The above make command should build docs when the source changes.

NOTE: Some types of changes require recleaning and building.
