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... Pierre
