Hello, the amazon 3M data on this [website](http://manikvarma.org/downloads/XC/XMLRepository.html) doesn't include metadata.json. It's not in both "BoW Features" and "Raw text"

Start by checking the linked Amazon2M archive and the Amazon 3M download page, focusing on whether metadata.json is included in either dataset package. The issue is complete when the metadata file's availability and location are clarified or the missing dataset asset is corrected.
