I still have this bookmarked to reply, Rob. But in the meantime, I wanted to share this:
So here is a tool I’m building for several groups that have similar needs to rank and compare attributes of entities, from tools to software to politicians, organizations, companies etc… It might be able to be applied to this need.
I have a question about the tools listed. Do they allow for easy interoperability between each other? More concretely, if I have a data set in Scapple how hard / easy would be to export the data and import it into Kumu? Fundamentally all these tools operate with graphical (as in graph theory with nodes and edges) data structures with annotated nodes and edges so in theory they should all be interoperable but I haven’t used any of them so has anyone tried the experiment?

Tricky stuff @davidk01 - Obsidian uses Markdown files as the underlying storage, so that is somewhat portable. Links are expressed with square brackets.
Many mind-map tools export Markdown. Many tools export JSON format.
But whether a second tool correctly interprets the JSON is a whole different thing.
I think Markdown (text files) maximizes your chances but the more graphical a tool is, the less likely that the graphical features are retained. Others would have to talk about Kumu.

Scapple files are XML, so in theory not rocket science to migrate, esp if you care mostly about node-text and links, and less about styles and physical/visual placement, etc.

</Note>@peterkaminski @Jerry and other Brain users…
Check out v12 that just dropped, total game changer for The Brain! Adds many features from Roam/Obsidian.
Jerry, you may be running an older version of The Brain given your web publishing needs, but you might want to check out v12.
Here are their release notes: https://www.thebrain.com/blog/version-12-beta
Cheers,
Rob.

Hmm, interesting Rob, thanks!
Still doesn’t tempt me enough to really try TheBrain, though, I think. But it does add to the reasons why I should. 
Oh, i thought you already were a Brain user, that was why I tagged you. Must have been confused with someone else!
Aaaaaalmost upgraded to v12 just now, but don’t want to destabilize my Brain b4 the election

As I have been with The Brain for a long time and also use Markdown tools - nvAlt and more recently Obsidian… I noticed that the unit in The Brain is a “thought” and the unit in Obsidian is a “note”. While a subtle difference, I think it influences how you use a given tool. I think TB is more about organizing and linking thoughts which may be a URL, a file, a note you write. Obsidian is more about writing notes where you can also link to things but not “attach”. Just an observation.
Yes! And this conversation about links vs nodes, thoughts vs notes, etc, is a great topic for us as we explore what a future OGM platform of platforms might look like.
@skreutzer, I appreciate your emphasis on the tech requirements coming (at least partially, from what we need for focus and situational awareness.
Btw, the “we” in my project is not we as individuals, but we as organizations/communities, and social systems.

I think you should download and run a subset in parallel and see what it looks like for you… It is not without bugs!
