OpenSCD add-ons are add functionality to extend the core functionality. It allows to experiment (with out commit it directly to the core) and add functionality for just a small group of users. Once an add-on is used a lot and is considered stable, it can become a part of the core functionality.
ADR
Alternatives for Add-ons are
- Mixins
- Wait to solve it in OpenSCD-core (thus long discussions, testing etc)
Possible Addons:
- Setting
- Wizarding
- Waiting
- Logging
Since the functionanlity is not fledged out. The idea is to start with an add-on. Once the are stabel, they can be merged into OpenSCD-core itself.
Not needed any longer compared to OpenSCD monolith architecture:
Hosting => This is solved in OpenSCD-Core.
Editing => This is solved in OpenSCD-Core. Without editing, the app gets useless.
Plugging => This is solved in OpenSCD-Core. Without plug-ins, the app gets useless.
