Lazy evaluation of semantic mapping rules
Jonas Rutishauser · Repository for Publications and Research Data (ETH Zurich) · 2008
The concept of Is-a Rules described in the master theses "Mapping Data to Queries" allows the integration of XML data enabling an object oriented usage of XML data items.In this paper it is described how to implement this concept in an efficient way.The rules are now longer evaluated eagerly at the beginning but lazy while processing the XQuery.
