Returning back to the original question. From my perspective I think the proposal in STYLE-609 should be adopted. And I haven't seen anything mentioned that suggests that the idea should not happen. Just that there are difficult issues to overcome. It seems to me that what the Instrument ontology should be is far from being settled. And I think that if we ignore the UI while developing that ontology; we risk creating an obtuse ontology that is difficult to use; with the result that we get bad data, or no data. We need to make the task of entering data easier, not harder. And if we have an inherently more complex data structure; the burden will be on the UI to aid the user in overcoming that complexity.
So back to adoption of STYLE-609; my vote is to go forward with it; but that the first step in moving forward is to settle the Instrument Ontology design and how that design will be integrated with the UI.
