Ask HN: How to preserve my Flickr, including metadata?

With the uncertain future of Flickr and Verizon, I no longer want to stay with Flickr. I am wondering if there is a way for me to download/transfer my photos to another service AND preserve comments, text, etc attached to that photo?

I have many many photos that I've painstakingly written notes about so I can remember the details and I would hate to lose all that effort.

If there is no solution anyone can point me to, I may just take it on myself as an opportunity since I know i'm not the only one that would be happy to make a clean exit from Flickr.
