## Outcome
* CONFIDENCE_BASIS
* Outcome written as a comment in [PR 368](https://github.com/eiffel-community/eiffel/pull/368)
* How to notify delivery of products delivered as source code?
* Outcome to be written as a comment in [Issue 219](https://github.com/eiffel-community/eiffel/issues/219)
* The new event should be called EiffelSourceStateLabelCreatedEvent with a single name field that describes the name of the tag. The event type name was deliberately chosen to be tool-agnostic.
* The event has a mandatory link named e.g. SOURCE_STATE that indicates the repository and commit that the tag refers to.
* An optional PREVIOUS_LABEL link can link to the semantically previous tag.
* We may want to add optional fields for the type of tag (with an implementation-specific value space, presumably) as well as the creator and submitter of the tag (similar to fields in SCS), but maybe those should be left out for 1.0.0.
