Storing meta information within the PDF

Hi all of you!

I am certainly not alone using quickpdf to build pdf document using some kind of merge mechanics.

This library is great. What we offer our customers is the following:

at design time,
1- they build an arbitrary pdf that includes form fields, in the editor they wish, typically a professional version of acrobat,
2- they describe the merge mechanics within our package, let us call this information, the meta information, it is currently stored in the pdf form field "description"

at runtime,
1- the software reads the pdf content and loads the meta information stored in the pdf form field "description",
2-perform the creation of a new one, paste the content (non form content) ,
3-rebuilds the "dynamic content" based on the meta information stored in the pdf form field "description", build the string and graphical resources and embed them,
4- possibly loops when the user does request multiple pages.

Time-and-resource-consuming, but quite workable. The users seem to like it. We would like to improve the process though and embed more tuned-up "meta information" used for the merge into the pdf.

This extra information is currently outside the pdf in an xml ut8 resource.

We understand there are more than one way to store extra data within a pdf. What would be the best way to embed the data? In our view, this meta data should be best kept "not visible" from end-users running they usual tools.

Since I know very little about the subject, any input welcome?

Hi Ingo,

Thanks for the information

The volume of functions available is this library is impressive
