Re: Categorization + Whether a POI must have location

Vinod -

Well, I would suggest we keep life (and any standard) simple and stick to
POI's that have location. That is broad enough. As for categories, the
geospatial community has dealt with categories (taxonomies, classification
schemes, etc) related to location for a long time. Typically categories
are handled by reference because a location can have many associated
categories. Personally, I would not even consider trying to define
categories or a world categorization schema. Their are domains of experts
that have defined taxonomies and classification schemes for their domains
of interest, such as TDWG for botony, OneGeology for geological structures
and lithology, and WMO for meteorology. All of these domain related
categories could be categories associated with a location.
