Super noob question: is it possible to show the metadata inserted with hyperref into the generated pdf itself? I don't mean to set them during generation, that would be easy.
I know that is not possible or somewhat hard to search and replace strings of text into a pdf after creation. I've some nice LaTeX invoice template, where normally, only some data changes.
I would like to use C or Objective-C to change those data after the PDF is generated. It seems to me that the metadata are, maybe, more accessible programmatically and I would not like to loose the excellent LaTeX typeset text of the PDF.
I would like to use metadata as some sort of baked in database.
Am I crazy?
For example, the "author" field could be set to a placeholder value like XXX, then I would later set/change it by only accessing PDFs metadata, programmatically (in other words in post-production without LaTeX).
It's like a fillable pdf but with metadata as a mean to update the text.
I know it could be an automation distorted idea but the problem arise from the usage scenario. I would like to produce a simple invoicing app for iOS (iPhone and iPad) and I would like to use the nice typeset pdf I created with LaTeX. I know i can't embed TEX into the app because of various licensing problems. At the same time I don't like to depend on an external, network reachable, TEX engine like scribtex.
