Decks¶
Cards are organized into decks for focused study sessions.
Deck Assignment¶
Deck assignment follows this priority (highest to lowest):
deck:in fence metadata — Per-card overrideosmosis-deck:in frontmatter — Per-note override- Folder path — The note's folder becomes the deck name
Per-Card¶
Per-Note¶
By Folder¶
A note at Vault/Languages/French/greetings.md automatically belongs to the Languages/French deck — the full folder path, not just the parent folder.
On the Dashboard these nest and indent to match your vault's folder structure. Intermediate folders that hold no cards of their own are pruned away, so you only see levels that mean something. Decks you assign explicitly (via deck: or osmosis-deck:) always keep their full slash-separated hierarchy, pruning or not.
Line Cards¶
Line cards follow the note's deck (osmosis-deck frontmatter or folder path). They count toward deck totals by default; exclude them with osmosis-line-cards: false in the note's frontmatter, or globally via Settings > Osmosis > Include line cards in decks. Excluded line cards stay studiable in place (contextual and spatial modes) — they just don't appear in decks or sequential study.
Hierarchical Decks¶
Decks are hierarchical, separated by /. For example:
The Dashboard shows this as a collapsible tree. You can study:
- A single deck — Just the cards directly in that deck
- A parent deck — The deck and all its sub-decks
- All decks — Every card across the vault
Automatic Inclusion¶
Instead of adding osmosis-cards: true to every note, you can auto-include notes by folder or tag in Settings > Osmosis:
- Include folders — Any note in these folders generates cards
- Include tags — Any note with these tags generates cards
This pairs well with folder-based deck assignment — add a folder to the include list, and every note in it automatically generates cards organized into the right deck.
