Obsidian Tag
A string which can be associated with an Obsidian Note.
They can be added inline to the content of the note by adding a hashtag symbol (#) followed by the string, or they can be added to the Obsidian Metadata.
It can only contain the following characters: 1
- Alphabetical letters
- Numbers
- Underscore (
_) - Hyphen (
-) - Forward slash (
/) for Nested tags
It must also contain at least one non-numerical character.
Nested Tag
A tag which is nested in another tag by using forward slashes (/) in the tag name. This creates “folders” for the tags to be in. 2
How to use
Tags should only be used for two things:
- Ephemeral data - Such as a temporary status like
#todoor#read. These tags are not expected to be part of the knowledge base and are just a way for me to see what needs to be done. 3 - Views - To make it easier to select a subset of notes in the graph view that would be otherwise difficult to make a search of. This is useful especially when the subset of notes is not otherwise separated cleanly into a distinct hierarchy such as a folder in the file system. 4
