Semantic Rules

Element Identification

• All rings and chains must have unique identifiers within pattern scope
  
• Identifiers follow pattern: elementtype + number (e.g., ring1, chain2)
  
• Custom names allowed: center_ring, petal_chain

Pattern Import System

• import "path/to/pattern.tatml" as motif_name loads external pattern
  
• Imported patterns become reusable components
  
• Pattern elements accessible via motif_name.element_id

Pattern Usage & Connection

// Use imported pattern with connections
motif1: use flower_motif with {
    connect ring1.picot1 to flower_motif.ring1.picot3
}

Picot Addressing

• Picots automatically numbered 1, 2, 3... in order of appearance
  
• Named picots override automatic numbering for that position
  
• References use dot notation: ring1.picot2, chain1.join_here
  
• Cross-pattern references: motif1.ring2.picot1
