All, long/lat coordinates are very useful to describe points but they don't tell us anything about the scale/size of the item. For example, if we attach a coordinate to a city then this means something really different from a coordinate on a specific restaurant in that city. The practical problem I am facing right now is that I am developing a map browser for our ontology editor, so that it can show Google maps for the selected object (assuming it has coordinates). However, when the user navigates to a given resource, how can I determine a useful zooming of the map - here I would need something like dimension or area to get an idea of whether to show the whole city, a suburb, a block, or a street or backyard. What about introducing an optional but recommended property for scale or size? The onion stuff could help, but I don't see a standard property for this in the vocabulary. Alternatively there could be an area class, but this may complicate querying and using the vocabulary. I guess this may return the group to the discussion about the size of the new vocabulary, and where to set the boundary. But my feeling is that some scaling information is critical for any form of visualization. Thanks for any comment, Holger
