[RDF] Progres report

[Jonas Liljegren]

I have woked full time on Wraf for some time now.  The system
continues to evolve.

I find it relatively easy to discover the existence of bugs in the
system.  To find the source of the bugs can, on the other hand be,
quite time consuming.  But the system feels stable.  And thats nice,
considering the chaos that's going on inside.


I have restructured the jumptables by extracting the dynamic
properties.  The value of LS:size and LS:level now looks like ordinary
properties, but are in fact calculated by functions provided by
interfaces.  The RDFS:subClassOf should also be a dynamic propertu,
but that's not done yet.

The RDFS:label predicate became a testcase for the connection between
the core and the interface.  The DBI interface stores the label in a
special field, apart from other properties.  But the core (now)
handles RDFS:label the same as other properties.  This wa an important
test, since you should be able to construct an interface using a
custom database for your data.

This change led to some restructuring and simplification of the
declaration and storage system.  I think the number of methods has
decreased.  And this should also result in some speed increase.


The latest CVS commit is tagged as Release-v0_0452
