## Topics

* Mattias: CONFIDENCE_BASIS (new event link in CLM) - [PR 368](https://github.com/eiffel-community/eiffel/pull/368)
    * also in relation to potential change of VERIFICATION_BASIS in IV
* Magnus: How to notify delivery of products delivered as source code? - [Issue 219](https://github.com/eiffel-community/eiffel/issues/219)
* Other PRs / issues of your choice - please raise your concerns!

## 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.
