Coordinating With Other Plugins¶
Plugin names are unique, and collisions are not tolerated by the framework. This means if you want to name your plugin
dada2, users will not be able to have your plugin and the https://github.com/qiime2/q2-dada2 plugin installed in the same deployment at the same time.
Action names are not globally unique, but rather are namespaced within a plugin’s domain.
Semantic Types, Formats, and Transformers are registered globally, like plugins, again, if you choose to use an existing name, this will prevent users from deploying both offending plugins concurrently.
There are a few strategies the QIIME 2 developers have employed to work within these limits:
Most types, formats, and transformers are registered in a single plugin: q2-types. This prevents circular imports. For many 3rd-party plugin developers, this means most typical types and formats are available within a single import.
- Plugin naming takes one of two approaches, typically:
The name matches the source tool being wrapped (e.g.
The name is some generic descriptor, like
- Action naming typically takes one of two approaches:
The name matches a subcommand or method on the source tool being wrapped.
The name is a generic descriptor, and typically is written as a verb (but not exclusively).
