#Note/Tag/Types #Note/Permanent Multi-layered tags provide a hierarchical categorization for the note, from a general subject to more specific thematics. This approach can help in organizing and retrieving information with precision without over-tagging the notes. There are multiple benefits of multi-layered tagging: 1. **Precision**. The hierarchical structure allows for precise categorization, ensuring that each note is tagged with the exact level of specificity required. 2. **Enhanced Information retrieval**. Multi-layered tags facilitate advanced search and retrieval, allowing you to pull up notes at any level of the hierarchy while keeping the context. For example, `#Store/Tag` and `#Note/Tag` are two different subjects. You can find `Tag` in of different context with one search and refine your query accordingly for desired information. 3. **Evolution & Adaptability**. As your digital garden grows and your understanding of different subjects evolves, the multi-layered tagging system can accommodate new layers or adjust existing layers. 4. **Intuitive & Simple**. We are used to structural hierarchical ways to organize our information, file folders, book index, etc. Multi-layered tags share the same concept, where would you store this piece of information on your computer file system? Think about the folder path you would create and use it as the tag. > [!tip] The 4-layer Rule > Try to keep your tags to be at most 4 layers, and each note has at most 4 tags. This principle pushes you to come up the most meaningful tags without over-tagging notes for your note taking system. **Format**: `#<Subject>/<Sub-Subject>/<Thematic>/<Sub-Thematic>...` **Examples**: - `#Biology/Genetics/DNA` - `#ProgrammingLanguages/Python`
