+
+@itemize
+ @item An extensible framework that will support robust spatial indexing
+methods.
+ @item Support for sophisticated spatial queries.  Range, point location,
+ nearest neighbor and k-nearest neighbor as well as parametric queries (defined
+by spatial constraints) should be easy to deploy and run.
+ @item Easy to use interfaces for inserting, deleting and updating information.
+ @item Wide variety of customization capabilities.  Basic index and storage
+characteristics like the page size, node capacity, minimum fan-out, splitting
+algorithm, etc. should be easy to customize.
+ @item Index persistence.  Internal memory and external memory structures
+should be supported.  Clustered and non-clustered indices should be easy to be
+persisted.
