All the "official" entries have comments on them, so if you see something without a comment, it's up to you if you wish to fill the entry or not. I also recommend that if you add a new entry or see one without comment, that you add a comment.
Yeah, about that: I don’t know what categories are used there. For example I have added „food“ and don’t know, what I should write in the comment.
I think "Ware category" would make sense here.
You can get an overview of the comments I used if you export the glossary to a csv file.
