open-science-catalog-validation

Validation for open-science-catalog-metadata.

Instructions

To run validation do the following:

npm install ESA-EarthCODE/open-science-catalog-validation

Then, inside a folder containing a STAC structure compatible with Open Science Catalog, run:

open-science-catalog-validation ./{eo-missions,products,projects,themes,variables}

Example for single file validation:

open-science-catalog-validation ./projects/3d-earth/collection.json

How it works

This validation package is based on stac-node-validator. Additional to generic validation following the STAC spec it does some custom validation (see ./validate.js).

Open Science Catalog STAC schema

Open Science Catalog requires a certain STAC structure for its entities (products, projects, variables etc.). The schema for these can be found in ./schemas.

These schemas can also be used for e.g. automatically rendering an input form.

To access the schemas in a dereferenced format, use the provided GH pages endpoint, e.g. https://esa-earthcode.github.io/open-science-catalog-validation/schemas/projects/children.json.

Development

For development, copy some compatible folder structure into the root folder, then run npm install follwed by a npm test.
