Use PDF file's embedded creation date

Hi,

I'm trying to find a way to use Hazel to recognize the creation date found in some PDF files' properties (accessible hitting cmd-I in Preview), which is not the same than the creation date of a copy of the file that sits on my computer.

As an example, my bank allows me to download PDF documents that were each created on a different date in the past. If I download them today, the creation date of all the files will be today in the Finder.
As if I open the files in Preview and hit cmd-I, I will see the actual creation date of these documents.
See the difference for yourself in the following screenshots, taken for the same file.

You all guessed I'd like to have Hazel rename all theses docs using their embedded creation date.

Thanks for your answers,

Guillaume

You'll need to check the other Spotlight attributes. For instance, there might be more listed under "Plus d'infos".

Thanks for your answer,

So did I, but I can't see any other creation date :

any clue ?

If you are comfortable using the command line, you can also try the "mdls" command on the files. It does a full metadata dump. See if any of those dates correspond with the date in the file.

Well, that is the output of the mdls command on that file :

no luck there then.

But if I look into the PDF with a text editor, the creation date i'm willing Hazel to use is encoded after a PDF tag as follows :

Code: Select all: %PDF-1.4 %‚„œ” 1 0 obj << /Creator (Exstream Dialogue Version 6.1.019) /CreationDate (D:20100216221953)

Would you suggest any way to make Hazel use that ?

Thanks

You'd have to write a script to extract it. It's too bad that Apple's Spotlight importer drops the ball here but I can't think of any other way to do it now.
