When you have the Annotation you can get its Dictionary and then add whatever keys (with whatever values) you want. Then you can just scan all annotations and check for your key.

Be sure to register your prefix as described there as well. Ok, from the specification I understand how to register for a prefix and include the information about additional extensions in the PDF catalog. But what I don't understand is how to store information per annotation to identify it, using PoDoFo. So, I'd like an identification *per annotation*, not *per document*, because some annotations in the document might have been created by some other application, and only some created by my application X. > > 2 - Sure.
