Only if someone figures out a way to pick the discovered metadata options as well as the mark 1 eyeball does

Yeah it is not an easy task, but an impossible task for 1 unless you're only updating a handful of items.

The current Download metadata and covers option from Edit metadata is a pretty decent example of what is wrong with automatic download and import of metadata. I have yet to find a metadata source that is even close to trustworthy. By trustworthy, I mean automatically update 25 books and not have to modify the metadata and covers for more than 5.

I don't find it nearly as bad.

My current plan would involve, all automatically:

1. import new books files (epub,mobi,pdf) into a staging library.
2. remove all tags
3. filter out content which is not a book, news ect, and tag it.
4. create a list of all items where tag:false
5. for this list, update Metadata with the Kobo plugin (reject an update that would change either title/author)
6. send rejected items to their own library, Kobo rejects
7. create a new list of items where tag:false
8. for this list, update Metadata with the same criteria as before using the Goodreads plugin
9. send rejected items to their own library, Goodreads rejects
10. send all items with a tag to main Calibre library
11. send items which remain to another library, failed imports

With the tools available I think this will do an alright job.

Note: I talked about creating a list of items, but I think it would be better to process each item individually, it is very much a work in process.
