Just go to this link to see most uses of the colon:
https://taginfo.openstreetmap.org/search?q=%3A addr:housenumber=3, house number is an attribute (or a part) of the whole address source:date=2017-07-07, date is an attribute of the source tag. It is not the source of the date provided. building:levels=4, number of levels is an attribute of the building social_facility:for=seniors, who is the social facility for is an attribute of the social facility church:type=parish, type of the church is an attribute of the church On the entire first page there are only two tags that use colons as you said; ref*:*bag on place #10 and ref*:*ruian*:*building on place #34. That's why, when I created the original Wikidata proposal, I suggested brand:wikidata. Because Wikidata ID is an attribute of the brand. Janko
