Yes. foaf:topic is the inverse of foaf:page. > What's your opinion on that? Will that work with your software > applications? Or should we use foaf:topic instead? If so, in which > direction? To give just one perspective: In our http://sig.ma both would work fine. If you used foaf:page, then the homepage URL would be shown next to a label saying “web page”. If you used foaf:topic, then it would be shown next to a label saying “is topic of”. The first (foaf:page) is perhaps a little bit more straightforward. > Alternative 2: > > foo:microsoft a gr:BusinessEntity; > gr:legalName "Microsoft Corp."; > foaf:topic <http://www.microsoft.com/>. That's just plain wrong, as should be obvious from [1]. The document goes into the subject (domain), the thing that is the topic of the document goes into the object (range).
