I can’t express an opinion about the map of contents because it depends what moc means to you and how you want to build it.
There’s a lot of “conditions” you need to explore and clarify, because some questions only have an answer if you clarify concrete problems/goals.
- Can we use backlinks in yaml? Yes, I already said that. You just need to follow the right syntax.
- With dataview you can “target” any field in frontmatter, be it links, numbers, strings, dates, … Again, using the right syntax/format.
- About the creation of map of contents with dataview, well, as I said you need to be more concrete, you need to draw some relationship… For example, a chain of inlinks (an inlink to the current file and the inlinks for file linked to the current file… and so one)?
- Dataview create a dynamic results, not a static things. So, what we see when we run the code is a “live” render, not a raw content. If the content doesn’t exist in the raw markdown document, then you don’t see the dataview results in the graph view! Maybe there’s a solution for that, but I guess it applies a complex code in javascript with a mix of dataview and obsidian api…
I never try it, but you can explore breadcrumbs plugin…
