I performed some fairly major maintenance work on this topic.
I consolidated all the information from:
- https://snapcraft.io/docs/snapcraft-top-level-metadata
- https://snapcraft.io/docs/snapcraft-app-and-service-metadata
- https://snapcraft.io/docs/snapcraft-parts-metadata
onto this page, filling any gaps between them. I made sure to resolve any contradictions between this source and the others. The format had to change as a result – a single long table resulted in scrolling without navigation, and it wasn’t an enjoyable experience.
I also gave it a new title to better reflect what readers will find here.
We plan to provide updates to the schema and its formatting in due time.
