The Github organization EOAP includes a set of repositories with training material regarding the Earth Observation Application Package.
This set of repositories aims to:
- help developers create Earth Observation (EO) applications using the Common Workflow Language (CWL)
- provide an overview of the CWL, its key concepts
- how to build a CWL-based EO application using practical examples in field guides

Open and reproducible EO Application Package⚓︎
Many cloud-based solutions for workflows in EO are available to users today, but only few support reproducibility or comply with FAIR data principles.
This short tutorial demonstrates how EO Application Packages meet these requirements.

SpatioTemporal Asset Catalogs⚓︎
- STAC Item is the core atomic unit, representing a single spatiotemporal asset as a GeoJSON feature plus datetime and links: https://github.com/radiantearth/stac-spec/blob/master/item-spec/item-spec.md
- STAC Catalog is a simple, flexible JSON file of links that provides a structure to organize and browse STAC Items. A series of best practices helps make recommendations for creating real world STAC Catalogs: https://github.com/radiantearth/stac-spec/blob/master/catalog-spec/catalog-spec.md
- STAC Collection is an extension of the STAC Catalog with additional information such as the extents, license, keywords, providers, etc that describe STAC Items that fall within the Collection: https://github.com/radiantearth/stac-spec/blob/master/collection-spec/collection-spec.md
- STAC API provides a RESTful endpoint that enables search of STAC Items, specified in OpenAPI, following OGC’s WFS 3: https://github.com/radiantearth/stac-api-spec
