Or maxheight= 3 ft - original-easy-to enter "folksomomic" key (defaults either to metric or local usage, there are arguments for both) maxheight:metric = 0.912 - added either by power users or by post-processing That is the sort of conclusion I've been coming to with the is_in tag. It is useful to have an easy to remember but fairly free-form tag to capture mass observations and then gain extra value from it by by post-processing and name-spacing for more systematic/rigorous catagorisation.
