Save Metadata with XMP

PDF metadata can be stored in multiple ways, and XMP is the modern, standardized method for embedding metadata inside a PDF file. Using Aspose.PDF, you can update standard fields like Title, Subject, Keywords, and Creator, and then save them in XMP format to ensure wider compatibility and future-proofing. This method is recommended over legacy metadata storage methods.

1. Load the PDF file.
2. Set standard metadata fields.
3. Save metadata in XMP format.

def save_info_with_xmp(infile, outfile):

    # Get PDF information
    pdf_info = pdf_facades.PdfFileInfo(infile)

    # Set PDF metadata
    pdf_info.subject = "Aspose PDF for Python via .NET"
    pdf_info.title = "Aspose PDF for Python via .NET"
    pdf_info.keywords = "Aspose, PDF, Python, .NET"
    pdf_info.creator = "Aspose Team"

    # Save updated metadata
    pdf_info.save_new_info_with_xmp(outfile)
