If on the other hand you have a small range of set resources, and you want to distinguish them, then you might process it as (b). Compare: (a) ":doorColor" may be applied to any resource which is a type of :Car. (b) If something has a ":doorColor", then that something is a :Car. The second instance sound more like you are making deductions about something (what is X? Well, if it has a :doorColor, then it is a :Car), whereas the first sounds like you're going through a record of things and wondering which properties you can apply to, "you can use my property :doorColor, but only on something that is a :Car". -- Kindest Regards, Sean B.
