@lavlas, should we move this discussion into ODH or can we decide that in here?

[tumido]

@Lavlas basically all we are introducing are the annotations in the table above with status Proposed new, the rest is just summary of what we know about the already existing annotations that we're trying to populate during the import.

bump @lavlas, should I open a similar issue in the ODH? Who should we pull in for this?

[LaVLaS]

I created a linked issue in the odh-dashboard repo to reference this issue. We can track the final list of annotations in this issue since they are produced and reference this in the Dashboard documentation
