well, in theory it can. the model as is merely limits geometry to be _only one_ of the attributes. as Geometry is a proper attribute type we can easily add more than one, they won't be displayed though ;) > Object type can be used how about a new BLOB attribute type, signifying that the column contains plain bytes, in case blobs are delivered by the underlying data reader? > - to preserve original data as much as possible, but will generally not > survive > a complete roundtrip (maybe a more specific serialization format could achieve > this goal, but with format like shapefile, we will rapidly encounter the 255 > char problem). if it is not saveable w/o data loss the write should simply err out and give the user a chance to save it another way. as much as i understand the industry standardness of the shapefile format, we shouldn't strive to make it limiting factor for OJ data formats. > - to offer plugin developpers a way to store structured data for in-memory > usage > (e.g. multiscale display as suggested by Jukka).
