I am trying to figure out a way to edit what the Kindle 3 displays as the "Author" for PDF files that I have emailed to my Kindle. PDF editing programs, such as PDF-Xchange Viewer allow you to modify what is described as the "Author Metadata Field". HOWEVER, this is NOT what the Kindle displays as the Author. There is another field that is NOT listed under the Metadata that appears to be read by Kindle.

Allow me to elaborate. By using a Binary File Editor I was able to locate the "Properties | Author Metadata Field". In every PDF file there is a section of data that LOOKS like XML markup text entitled "x:xmpmeta". I must assume that is the 'usual metadata' section for the PDF file. Within this is a section entitled "dc:creator", and within this is "rdf:Seq", and inside that is "rdf:li" -- which holds letter-for-letter what is displayed in the "Properties | Author" field when you open a PDF. This is the usual Author Metadata Field. Of this I am very certain!

The problem occurs because the Kindle has decided to NOT use the String that appears there to display as the "Author". I do not understand why, I just know it to be true!

Instead, Kindle takes data that is NOT enclosed inside the usual metadata section -- that is, NOT nested in "x:xmpmeta". Outside of the expected XML markup metadata is another set of fields that list: Author, CreationDate, Creator (this time NOT referring to the Author but instead program that created the PDF file), ModDate, Producer, and Title. I have no idea what to call this section, but the Kindle seems to grab the string from the Author field here and it displays that as the "Author".

Now, I am at a loss to find a program that allows me to INSERT this secondary yet-unnamed "collection of fields" into a PDF file. If I use a Binary file editor and brute force stick that inside the PDF file, the file becomes "corrupted" per Adobe Acrobat. Now, the file MAY still work on the Kindle (yet to be seen -- until I get home), but it is clear the Acrobat does not like that (see my link below).

Has anyone figured out this mess before me?? If so, I congratulate you. If not, someone should -- or we should push Amazon to use the USUAL METADATA AUTHOR field to display as the Author!!!! I would love to be able to Edit the Author field that the Kindle displays for PDF files. There must be a way! Thanks for reading.
