I just ran into this myself and had a bug report rejected since this feature request already existed.
I’m not sure I agree with treating this as a feature request; not supporting reference-style links with URLs that work in other contexts should be treated as a bug as Obsidian is not correctly handling Markdown (for reference, see Basic Syntax | Markdown Guide).
I agree. This lack of support for standard markdown is the only thing preventing me from switching to Obsidian, as it doesn’t work with my existing notes. Nor would I even want to migrate them given the absence of this feature, since the whole point of that link style is that you don’t have to put long links in the middle of the text, possibly many times. It’s unfortunately a deal breaker for me, which is a real shame.
Obsidian claims to support markdown, but it doesn’t actually work. Clearly a bug.
A primary feature of Markdown syntax is its readability. Inline links suck for readability, meanwhile Obsidian’s way of making them (relatively) human-readable doesn’t conform to “proper” (Common) Markdown syntax at all and goes directly against the goal of making your vault portable and interoperable. …And yet Obsidian DOES support footnotes which aren’t part of the standard spec at all. What the heck?
link definitions are a very important feature of markdown when working on long documents.
This is just a notation, and user expectation is that using link definitions will provide exactly the same behavior as inline links. This is just a way to write the link elsewhere. It took me a quite a while of testing (even going back to CommonMark spec) to discover that in Obsidian link destinations were handled differently in both cases.
I also consider it to be more a bug, as it is provides an unexpected and systematicaly useless result (broken links are generated)
PLease add support to it, with full alignement on inline links, with support for images and embedding notes or part of notes
