That's not cataloguing, that's recording, and as far as I understand this is long ago done - cataloguing is those "all other details" which require expertise and time; all the things like figuring out that this coin is a roman coin from 1st century, and that other coin from the same find is from another location.

If it's long ago done, where is the wiki with 2.4 million photos? If it's not online it might as well not exist

Museums have huge collections of many things that are not online but which researchers can access locally.
