[Rdfapi-php-interest] Creating getters and setters based on RDFS

[<hen...@ya...>]

Not sure if this problem I am having is obvious - I hope it is!

What I would like to do is:

---------------
given an RDFS ontology (and later, OWL) I would like to be able to
easily create get, set, delete, and update functions - so that for any
class, their properties and inherited properties become part of simple
php functions  to serve as APIs for other applications.
---------------

Problem:


If you create an RDFS class like "Person"  - then you want to create
instances using the statement and resource API of RAP it appears that
instead of the desired

< ns:Person about="ns:person1" ns:hasTeeth=14>
</person>
< ns:Person about="ns:person2" ns:hasTeeth=14>
</person>

Using the statement api I ended up with one, completely incorrect
instance of a person

< ns:Person about="ns:Person">
	<ns:hasTeeth =14 />
	<ns:hasTeeth =14 />
</Person>

I also ended up with unneeded(?) <Description... > tags.

The ontology model looks like it understands classes and properties -
but I am reluctant to use the RAP ontology model because it looks to be
incomplete.
