If you want to have a look at how Octopus actually looks like, here's the link to my two recently published minute publications.
It is a piece of work I've been doing as part of the UKCCSRC project, and I am currently working on the full paper. I thought, let's use it as a template or example for the research community to kind of explore how the entire process works with micropublications.
And I just want to test whether the journals will be keen on actually publishing my paper. So I'll be updating everyone as we go along. Here's the link. You can see it does have a DUI number. It links the two papers so you can clearly see how the output is shaping up.
Let me know whether that is helpful.
