Why can metadata be defined, when it is not used at all? Metadata from inline test shell definitions can be read out via the REST API, metadata from external test shell definitions can't. What's the point in
defining metadata, if you cannot use it afterwards?

Why this limitation? Is there any reason, why it has to be an URL? Why not allow any string to be appended to a test case?

This seems like a dirty hack to me, quite contrary to the „keep your data clean“ principle.

Are there any news on this? What new features are planned?
Sorry for re-activating such an old thread, but the topic is still relevant for us. We would like to append metadata to test cases and test suites, and there does not seem to be a useful way to achieve this with
LAVA. Our actual goal is to include LAVA test results in the release notes for our OS releases. For this purpose, we need some kind of human-readable description of our tests, which shall be stored alongside the results.
As far as I can see from the database layout, metadata is a data field of test cases. Would you accept code contributions which add functionality for adding custom metadata to this field?
However, test suites do not have such a field. Instead, actions have metadata, which are not stored in the database but in dedicated metadata yaml files under /var/lib/lava-server/default/media/job-output/. Why
is that? Why not add a metadata database field for actions/test suites as well?
Do you have any ideas of how to achieve our goal using LAVA?
