As has already been mentioned, this totally depends on what you want to do with it. In our digital repository we have a policy of storing points (and polygons) as WKT. It's a well documented standard format that is supported by most GIS libraries. Since we're not doing any GIS queries directly from the repository it works fine. For our applications that require polygon comparisons, the data gets stored natively as polygons in PostGIS. For mapping applications that are built around points, using Solr's built in LatLon type can be a great option. For our geobrowse application (http://www.lib.unc.edu/dc/geobrowse/) our points are just stored in Solr as separate float fields, because all we're doing is plotting them on a map. I guess for us, we've found that multiple formats work best.
