If you have the means to read the metadata then you already have both the document and the decryption key. I am not aware of anything that uses metadata expect for locating data. Once you have the full document what use is it?
It seems that the metadata is not available until you have retrived and decrypted the document. At which point you have had to look in a key index of some description to retrieve the freenet uri and the decryption key. You will have used some type of metadata (possibly a plain text description, a list of keywords or something else) to identify which doc to retrieve, so the contents of the document are already known.
