Thank you for the tips. I am actually interested in enumerating metadata for all the "items" as defined by the API page ever uploaded. For example, one item = one ID:
Archive.org is made up of “items”. An item is a logical “thing” that we represent on one web page on archive.org. An item can be considered as a group of files that deserve their own metadata.
You did cause me to look at the API docs again, though, and I think I found something that does enumerate all item names, and as a bonus, it will keep you updated when changes are made: https://archive.org/developers/changes.html
We'll see how much progress I can make. It might take a while to get through all the millions of them.
Yes, I think so. I'll definitely use the example for downloading some of the files (.torrent, metadata file) once I have some items. But first I need to find all the items ever uploaded.
