The ID helps to distinguish instances of the same service that exist at the same time (e.g. instances of a horizontally scaled service). It is preferable for the ID to be persistent and stay the same for the lifetime of the service instance, however it is acceptable that the ID is ephemeral and changes during important lifetime events for the service (e.g. service restarts). If the service has no inherent unique ID that can be used as the value of this attribute it is recommended to generate a random Version 1 or Version 4 RFC 4122 UUID (services aiming for reproducible UUIDs may also use Version 5, see RFC 4122 for more recommendations). | `627cc493-f310-47de-96bd-71410b7dec09` | Yes |

-with naming schemas hinting at the type of a version, such as the following:
-
-- `semver:1.2.3` (a semantic version)
-- `git:8ae73a` (a git sha hash)

+Version attributes, such as `service.version`, are values of type `string`. They are
+the exact version used to identify an artifact. This may be a semantic version, e.g., `1.2.3`, git hash, e.g.,
+`8ae73a`, or an arbitrary version string, e.g., `0.1.2.20210101`, whatever was used when building the artifact.
