Suppose that a query is run against a RDBMS to get our source data. Example rows from the XML result set source file are shown below in Figure 1. The entire file can be found in the result set file EduRS.xml found in theexample/source directory of the online example. Also see Appendix C. There is frequently more than one row for a given person and the data may or may not be complete as indicated in the Figure 1 below.

In Figure 2 the rectangles represent data; the oval shapes represent object classes and the labeled arrows predicates. A namespace abbreviation is also given e.g. vivo or foaf. The string local:degreeLevel, like local:weakAttribution, is the name of a yet to be defined predicate - more later. The central object will be of type vivo:EducationalTraining as mentioned above.
