Hi

I had to parse PDF files for the OpenstreetMap project in france (data could be 
extracted from PDF generated from the cadastre)
I don't know how you plan to use poppler, but for this case, I could not extract 
any useful information from its datastructures. I instead had to use libpodofo. 
I don't think you can use poppler for Calligra needs (except if you implement a 
new poppler backend), but I'd be happy to be proven wrong...
