 def get_ocr_prompt():

-Your task is to meticulously analyze this image and extract all relevant information.
-
-Output Format Instructions:
-Provide your response as a SINGLE, VALID JSON OBJECT. Do not include any explanatory text before or after the JSON.
-The JSON object should have the following top-level keys:
-- "document_type_detected": (string) Your best guess of the specific document type (e.g., "Passport Front", "Passport Back", "National ID Card", "Photo of a person", "Hotel Reservation", "Bank Statement").
-- "extracted_fields": (object) A key-value map of all extracted information. Be comprehensive.
-    - For ALL document types, if a primary person is the subject, try to include: "Primary Person Name", "Full Name".
-    - List other names found under specific keys like "Guest Name", "Account Holder Name", "Mother's Name", "Spouse's Name".
-    - Extract critical identifiers like "Passport Number", "Document Number", "ID Number", "Account Number", "Reservation Number" FROM ANY PART OF THE DOCUMENT where they appear. Use consistent key names for these if possible.
-    - For passports/IDs: "Surname", "Given Names", "Nationality", "Date of Birth", "Sex", "Place of Birth", "Date of Issue", "Date of Expiry".
-    - For photos: "Description" (e.g., "Portrait of John Doe", "User's profile photo"), "People Present" (array of names if discernible).
-- "mrz_data": (object or null) If a Machine Readable Zone (MRZ) is present.
-- "full_text_ocr": (string) Concatenation of all text found on the document.
-
-Extraction Guidelines:
-1. Extract "Passport Number" or "Document Number" even from back sides or less prominent areas.
-2. Identify and list all prominent names. If one person is clearly the main subject, label their name as "Primary Person Name" or "Full Name".
-3. For dates, aim for YYYY-MM-DD.
-
-Ensure the entire output strictly adheres to the JSON format.
