This document discusses making PDFs "smarter" through the use of custom properties, exporting and importing metadata, sanitization, barcodes, and defining workflows. It provides definitions of PDFs and discusses their history. It also demonstrates how to add custom properties, export and import metadata, sanitize PDFs, generate 1D and 2D barcodes, and presents a real-world example of integrating these features into a document management system workflow.
Don't just pdf, Smart PDF

- 3. Definitions & Facts What is a PDF? Portable Document Format (PDF) is a file format used to present and exchange documents reliably, independent of software, hardware, or operating system. • Invented by Adobe. • Open standard maintained by ISO ( International Standards Organization). • Can contain links and buttons, form fields, audio, video, and business logic. • Can also be signed electronically Some Facts About a PDF
- 4. History • In 1991, Adobe cofounder Dr. John Warnock launched the paper-to-digital revolution with an idea he called The Camelot Project. • By 1992, Camelot had developed into PDF. Today, it is the format trusted by businesses around the world. • Today, Warnock's vision is alive, well, and evolving. Adobe PDFs preserve all the data in the original file - even when text, graphics, spreadsheets, and more.
- 5. Security • Password • Redacting sensitive information • Sanitization—Remove hidden data from a PDF • Digital signature using a private/public key pair Secure a PDF by
- 6. Conclusion • If you can share & reduce physical occupation of 1000 books to 1000 digital files resting in your lap. • If you can search for files, pages within seconds. • If you can sign, edit, comment, stamp a PDF. • If you can secure a PDF. • If all above can be done by a PDF, shouldn’t we call it SMART?
- 7. Not yet, until we make it smarter by predefining the workflow • Custom Properties. • Exporting and importing metadata. • Sanitization. • Barcode. • All together to create a PDF workflow.
- 8. PDF Custom Properties • Ability to add custom properties to store specific data. • ColdFusion can only read custom properties as of 2016 release. • To create custom properties we will use JAVA. • No need to load extra library, ColdFusion already has iText java library pre-loaded.
- 10. Exporting & Importing Metadata Metadata Includes information about the document and its contents, such as the author’s name, keywords, and copyright information, that can be used by search utilities. XMP The Extensible Metadata Platform (XMP) provides Adobe applications with a common XML framework that standardizes the creation, processing, and interchange of document metadata across publishing workflows.
- 11. Exporting & Importing Metadata Export Specify the source of the PDF and destination of the XMP file. <cfpdf action=“export” type=“metadata” source = “file.pdf” exportTo =“file.xmp”/> Import Specify the source of the PDF, the source of XMP file and the destination for the file to be placed. <cfpdf action=“import” type=“metadata” source=“file.pdf” importFrom=“file.xmp” destination=“PDF output file pathname” /or name=“PDF document variable name”/>
- 13. Sanitization Sanitize Removes metadata from your PDF document so that sensitive information is not passed along when you publish your PDF. • Metadata • Attached files • Scripts • Search indexes • Form data • Review and comment data • Obscured text and images • Unreferenced data • Links • Actions and javascripts • Overlapping objects Sanitize removes the following:
- 15. Barcode A barcode is an optical, machine-readable, representation of data; the data usually describes something about the object that carries the barcode. (Wikipedia) One-Dimensional (1D) Barcode Systematically represent data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional. Two-Dimensional (2D) Barcode Systematically represent data using two-dimensional symbols and shapes. They are similar to a linear 1D barcode, but can represent more data per unit area.
- 16. Barcode-1D Types One-Dimensional (1D) Barcode Types • UPC CODE • EAN CODE • CODE 39 • CODE 128 • ITF (Interleaved 2 OF 5) • CODE 93 • CODABAR • GS1 DATABAR • MSI PLESSEY UPC CODE CODE 39 ITF (Interleaved 2 OF 5) MSI PLESSEY
- 17. Barcode-2D Types Two-Dimensional (2D) Barcode • DATAMATRIX CODE • QR Code • PDF417 Used in tracking and marketing. Free to use, flexible in size, has a high fault tolerance, and fast readability. However, it can’t be read with a laser scanner. It supports four different modes of data: numeric, alphanumeric, byte/binary, and Kanji. It is a public domain and free to use. Used in applications that require the storage of huge amounts of data, such as photographs, fingerprints, signatures, text, numbers, and graphics. It can hold over 1.1 kilobytes of machine-readable data, making it more powerful than other 2D barcodes. Like QR codes, PDF417 barcodes are public domain and free to use. • AZTEC

Download ZXing ("zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. https://github.com/zxing/zxing 2. Save the library in your ColdFusion class path C:{cfserverhome}{cfusion}wwwrootWEB-INFlib 3. Restart ColdFusion server

- 22. Real case scenario Custom Properties Key pair value( TrackingNumber, WorkflowID) • TrackingNumber: unique ID (CreateUUID) to validate the PDF by embedding inside the barcode. • WorkflowID: unique ID (Database ID)definition to tell the PDF what to do next Export XMP (The Metadata) Export the metadata (XMP) file to folder structure by making the file name same as tracking number D:DMSxmp{trackingNumber}.xmp
