I really enjoyed this one.  It has a slightly different style asking questions at the beginning.  In fact, if you read this one first (I read it last) then it sets everything up nicely.  Do you plan to add any links across the Gemini papers so that relevant sections / words can be accessed by the reader.  There are lots of words and phrases here that could hyperlink across the the what paper.

Linked to the above, it is a bit of an isolated comment about CReDo on page 4.  Needs more detail (although probably not the best place to do so) or a link.

P5: The sub-headings don’t all work.  For example: Q: How do you encourage a new market in DTs? A: Legal barriers!

Ending still looks like it is work in progress?  As the final paper do you want a summary figure for all the Gemini papers – is it even worth including the same thing in all the papers to create more ‘glue’ and show where the principles introduced fit in the wider scheme of things?

Hi Tammy, 
Commented directly. Like Lee, I read in the order received but agree in his comment that this sets up and answers fundamental questions in the first two papers. 

A couple of comments relating to Society 5.0 and Open Source formats as well as a City Digital Twin example.

Kind regards, 

Khezar

Very interesting topics, but perhaps may be enhanced with some appendices of Digital Twins that are built to this standard.  For the IMF was any “standard” such as http://www.openoandm.org/isbm/
reviewed ?
If I came to this paper to consider “how” to implement a Digital Twin, I would leave disappointed (and perhaps frustrated)
