description: |
|
|
The directional orientation of text flow on an information carrier.
|
|
|
|
**Purpose**:
|
|
Captures how text is read/written on manuscripts, inscriptions, and other
|
|
information carriers. Essential for proper display and understanding of
|
|
historical documents from different writing traditions.
|
|
|
|
**Common Directions**:
|
|
|
|
| Direction | Scripts | Example |
|
|
|-----------|---------|---------|
|
|
| LEFT_TO_RIGHT | Latin, Cyrillic, Greek | Modern European books |
|
|
| RIGHT_TO_LEFT | Arabic, Hebrew, Syriac | Quran manuscripts, Torah scrolls |
|
|
| TOP_TO_BOTTOM | Traditional CJK | Classical Chinese scrolls |
|
|
| BOUSTROPHEDON | Ancient Greek, Etruscan | "Ox-turning" alternating lines |
|
|
|
|
**Relationship to WritingSystem**:
|
|
TextDirection is distinct from WritingSystem (ISO 15924 script codes).
|
|
A single script may have multiple historical or regional direction conventions.
|
|
|
|
**Usage**:
|
|
Used with `has_direction` slot in InformationCarrier and similar classes.
|
|
|
|
