| **BoxType** | Type of storage box with dimensions | `name`, `width`, `height`, `length` (in mm) |
| **Box** | A storage box in the lab | `id` (CharField PK, max 10), `box_type` (FK) |
| **ThingType** | Hierarchical category (MPTT) | `name`, `parent` (TreeForeignKey to self) |
| **Thing** | An item stored in a box | `name`, `thing_type` (FK), `box` (FK), `description`, `picture` |
| **Facet** | A category of tags (e.g., Priority, Category) | `name`, `slug`, `color`, `cardinality` (single/multiple) |
| **Tag** | A tag value for a specific facet | `facet` (FK), `name` |
| **Thing** | An item stored in a box | `name`, `box` (FK), `description`, `picture`, `tags` (M2M) |
| **ThingFile** | File attachment for a Thing | `thing` (FK), `file`, `title`, `uploaded_at` |
| **ThingLink** | Hyperlink for a Thing | `thing` (FK), `url`, `title`, `uploaded_at` |
**Model Relationships:**
- BoxType -> Box (1:N via `boxes` related_name, PROTECT on delete)
- Box -> Thing (1:N via `things` related_name, PROTECT on delete)
- ThingType -> Thing (1:N via `things` related_name, PROTECT on delete)
- ThingType -> ThingType (self-referential tree via MPTT)
- Facet -> Tag (1:N via `tags` related_name, CASCADE on delete)
- Thing <-> Tag (M2M via `tags` related_name on Thing, `things` related_name on Tag)
- Thing -> ThingFile (1:N via `files` related_name, CASCADE on delete)
- Thing -> ThingLink (1:N via `links` related_name, CASCADE on delete)
**Facet Cardinality:**
- `single`: A thing can have at most one tag from this facet (e.g., Priority: High/Medium/Low)
- `multiple`: A thing can have multiple tags from this facet (e.g., Category: Electronics, Tools)
