Guide line? Possible?

 From least to most specific.

I think that should be the overall principle .. appears to be a principle inuse by OSM .. at least I think so?

More specific?

I would reject sells:children_cloths and accept sells:cloths:children as this is more universal method (applies to bread etc)?

I would put the brand last - as that is more specific than the type (of clothing, bread etc).

I think the last would be sufficient, and should indicate that most, if not all, products made by that firm are for sale.

But the first 3 would be very clear that at least those 3 types are sold (but tagging rearranged to brand last).
At least for some tags OSM has two complimentary kinds of tagging in the data base.

e.g. oneway=no compared to no tags for oneway. Both are taken as meaning the same thing. There are others, but I cannot think of them now.

1:1 substitution for all values?
cloths:women becomes sells:cloths:women ?

Similar for

the tag stamps=yes becomes sells:stamp=yes Or better yet would be

As both exist in various countries! And there could be more different kind of stamps?

! You see I have not gone far in my thinking ... but certainly further than others.

Yep. And there will be future 'problems'.
