thanks a lot!
I've read about EasyCatalog. This might be a solution.
Nevertheless ... it looks pretty complicated.
My PIM is able to export specific (and valid) XML-Files (for single products or all products at once) with the correspondig attachments that I could import into my InDesign-File.
The only thing I would have to do for that is to create placeholders and tag them correctly. I think, this could be much easier for the graphic designers, too.
Furthermore I see some advantages by using the XML-transfer via PIM>EXPORT and InDesign<IMPORT.
Do you know any important reasons for using a Plugin for the data-transfer from PIM to InDesign?
I would imagine that a "real" database connection has lots of advantages if you have data that changes a lot.
In those cases you typically would not want to do these manual export<->import steps each time but just update the contents of the pages.
Plus, ideally, a database connection would be pretty transparent for the designer.
