gRegorLoveGoodreads has "bookshelves". There's three core ones you can't remove: read, currently reading, to-read. They also have an 'exclusive' flag, so a book can only be in one of them at a time.
gRegorLoveFor a while they didn't support the concept of re-reading a book, but they've added some type of records so you can track multiple start/end dates for re-readings
[jgmac1106]maybe what you do is make a read post, and want-to, start, and finish are webmentions you send to that post?...or do you go back and revise your read post and change the p-category status?
[jgmac1106]then maybe IMO in terms of iwbc long term be nice if there were input fields that let you select want to, started, and finished, and each time you updated your post it would add the p-category and a dt-edited?
[Vincent]hello, I’ve been digging through the microformats wiki but I can’t find an answer. What do the p-*,u-*,dt-*,e-* prefixes mean on the relevant MF tags?
