| ### Artifact | ||
| _Artifacts_ are items or software packages generated in a CI/CD [pipeline](#pipeline), for example a built binary or a Docker image. An artifact should be possible to identify using a purl (package URL). An artifact is often the subject of a test executed or a delivery performed within a CI/CD [pipeline](#pipeline). |

This definition is enough, but maybe we could add that artifacts aren't always only things that will be included in products?
They can also be test artifacts, i.e. artifacts only created to be useful in some specific test scenario. For example, when product software is combined with testing harnesses. Such artifacts are also defined by Baselines to record what versions of testing harness software were used.

Agreed. Will add something along those lines.

Good definition!
As with Artifacts, we could add a comment/example of how Compositions/Baselines can be used to record test environments as well as product hierarchies.

Yes, will do.

| ### Event | ||
| An Eiffel _event_ is a broadcast notification telling any consumer about an event occurring in the CI/CD [pipeline](#pipeline). |

Again, good definition, I have heard many times that people still don't understand really what an event is/should be.
It is not a message sent intending to cause some side effect somewhere like a remote procedure call. It is just a notification to the world that something has happened. As such, an event should not contain information that is not directly associated with what happened, even if it is tempting to use them as carriers of general "system" type information.

Good point. I'll elaborate a bit more on the event definition, and probably also add a link definition explaining a chain of events.

| ### Composition | ||
| A _composition_ is an immutable grouping of specific versions of [artifacts](#artifact) and/or [source changes](#source-change). It is more or less the same as what is elsewhere sometimes referred to as a _baseline_, which can be explained as being a fixed reference point used for comparison. A composition is often defined with the purpose of enabling downstream [artifacts](#artifact) to be generated. | ||

A composition is often defined with the purpose of enabling downstream artifacts to be generated. It gives full traceability on what software pieces that were used to generate the artifact, being it a product artifact, a test harness or some other kind of generated artifact. |

"being it a product" should perhaps be rephrased to "be it a product"?
