Personally, I'm not trying to model all of human knowledge in my Org files! I suppose if you were an academic researcher it might be a bigger issue, but I count 71 different tags in my agenda files, and I don't feel overwhelmed. You can get a bit of tag hierarchy with tag groups, but admittedly only a bit. > So rather than: > > ** some construction :plastics_engineering: > > > I would have: > > Engineering.org: > * Plastics > * Houses > * … > > > I understand you use tags and „tag search“ to be able to look for > bits of a particular topic in a file which is not related to the > topic. > It would be better to have a tag that in addition links to a > particular tree.

To my knowledge, no one's implemented a reverse link lookup, but it should certainly be possible. Using the <<<foo>>> link notation as a tag, however, would probably end up being more work (and more confusing) than it's worth. E
