This message contains my original Java version of a set of classes,
the RDF schema representation (corrected so that rdfs:range and
rdfs:domain are transposed), and an autogenerated XMI representation
contributed by Don Park. The XMI representation is painfully verbose,
probably because it was created by a machine rather than by a human
(it also seems to define a lot of generic Java stuff), so perhaps it
could be made much shorter with human intervention -- can anyone trim
it down?
Here's my original Java version, again:
====================8<====================8<====================
public class Entity
{
public String name;
public String startDate;
public String endData;
}
public class Being extends Entity
{
public Being sire;
public Being dame;
}
public class Person extends Being
{
public String nationality[];
}
====================8<====================8<====================
Here's a corrected version of my RDF schema, with rdfs:range and
rdfs:domain transposed:
