See this Nextcloud server request of tagging across all apps. Could make an excellent compliment to recently announced Projects functionality in Nextcloud 16 + the automation of workflows via tagging that will be available in Nextcloud 18.
Direct quote from the Github request for system wide tags across all apps:
I would like to be consistent:
- Have tags everywhere, thus allowing to have many tags for one object
- Tags list being shared between apps.
Additional context
- This will allow a consistent taxonomy on your objects (tasks, bookmarks, …)
- This will induce a capability to find all objects related to a tag.
Example:
I use the tag recipe to track my recipes, and the tag cooking for the things to try in the kitchen
I have a pdf of a recipe, which I tag with cooking
and recipe
I pasted another recipe in a note, which I only tag recipe
because I already did it with my mother last week.
I bookmarked a third recipe, and tag it with cooking
and recipe
I uploaded a photo of a recipe from a book taken during a trip in Italy, which I tag with cooking
and recipe
I create a task Schedule invitations for cooking tag which I tag with cooking
We may then envision to have a global tag search, so that if I search for tag cooking
, it will show me all the objects tagged with it (files, photos, tasks, bookmarks, notes).
