I am running 0.6 b13, and I have a question/observation.

I have been updating metadata on many of the 700+ books in my library. My next step is obviously to convert the books so that I can have clean copies with updated metadata.

I tried to do a mass-convert of my entire library, but calibre choked on that. I was able to convert 100 books, but two or three had problems and didn't convert. I haven't gotten around to completing the rest yet.

However, this points out to me that I don't have any clear way of knowing which I've already converted, which choked, and which have changed meta-data but haven't converted yet. I believe the date information only shows when the library entry was first made (correct?).

I'm not sure about the best implementation, but here are a couple thoughts. 1) An additional date field that shows the last conversion time; or 2) A flag that can be set manually and is set automatically when the meta data changes. This flag shows that the book needs to be converted. You could then do a search/filter on the flag to see books that need to be converted. Every time a book is successfully converted, this flag would be reset.

Comments?
