I don’t know if you’ve clicked the icon in the middle of the bottom of the page on asset views:
that toggles the “asset stream” view, which is the only real relationship I’ve thought about with respect to tags: it’s the other “nearby” assets: where “nearby” means that they are also associated to any tag for the current asset.
The only other relation I’d thought of before is via tag hierarchies, but what you’re suggesting would be in addition to this.
It’s been a while since I’ve used SmugMug. How do they handle related tags? (I could only find this help page).
Agreed. Know that the nerdy “namespaced” search terms (like kw:beach) is totally optional: just searching for beach should work as well (and find any asset in any directory with the word beach in it, as well).
Yup! Make sure you vote for 🌍 Support reverse-geocoding, to automatically tag assets with location names
