יחידה:PropertyLink

יחידה זו משמשת כדי לקשר בוויקיפדיה לפי ויקינתונים. היחידה מיועדת לשימוש בעיקר בתבניות וכוללת את הפונקציות הבאות:

• property או מאפיין - לקבלת קישור לפי "קביעה" מוויקינתונים
  • פרמטרים: שם המאפיין (property) המתאים (בצורה של P123). למשל בערך דמויי כלב:
    • {{#invoke:PropertyLink|property|p171}} - יחזיר "[[טורפים (סדרת יונקים)|טורפים]]" (טורפים), להבדיל מ־[[{{#property:p70}}]], שיחזיר "[[טורפים]]" (טורפים), שהוא דף פירושונים.
• label או תווית: דומה לפונקציה הקודמת, רק שלא מחזיר קישור אלא ללא קישור - מחזיר את התווית (label) וללא תלות בקישור כלשהו שקיים או לא קיים בוויקיפדיה בעברית
  • פרמטרים: שם המאפיין (property) המתאים (בצורה של P123)
• imageLink או תמונה: פונקציה שמחזירה תמונה שמתאימה לשילוב בתבנית מידע בערך.
  • פרמטרים:
    • פרמטר ראשון - (אופציונלי) אם לא מקבל פרמטר בכלל משתמש ב־d:Property:p18 (מאפיין כללי של תמונה), אחרת משתמש בפרמטר המאפיין המכיל את התמונה
    • width - גודל התמונה (אחרת 220px)
• hasEntry או יש פריט: פונקציה שמחזירה "1" אם לערך יש פריט ויקינתונים; או "" אם אין.
  • פרמטרים: אין

ייתכן שבעתיד תהיה תמיכה מובנית לפחות בחלק מהאפשרויות הנ"ל ראו בmeta:Wikidata/Notes/Inclusion_syntax#Items
