[Rdfapi-php-interest] RAP bug report

Perhaps I am doing something wrong?

I am using php 4.3.10 on windoze.

Summary:

Can not create a RES model then add it to a DB/MEM model.

Error(s):

 - function fails
"Call to undefined function: writeashtml() in..."

 - adding resource model to a memmodel, or db model fails

"Fatal error: RDFAPI error (class: MemModel; method: addModel): Model
expected..."

Code:

$modelURI = "http://somwhere.net/something/"
$modelURI2 = $modelURI.'#';
$rdfuri = 'http://www.w3.org/1999/02/22-rdf-syntax-ns#';
$rdfsuri = 'http://www.w3.org/TR/1999/PR-rdf-schema-19990303#';



// Create an empty Model
$model = ModelFactory::getResModel(MEMMODEL, $modelURI);


$mammalURI = $modelURI2.'Mammal';
$personURI = $modelURI2.'Person';
$rdfuriAbout = $model->createResource($rdfuri.'about');

$person = $model->createResource($personURI);
$mammal = $model->createResource($mammalURI);


$hasTeeth = $model->createProperty($modelURI2.'hasTeeth');
$hasName = $model->createProperty($modelURI2.'hasName');


//more code here


$model->writeAsHtml(); //fails
$model2 = new MemModel($modelURI);   
$model2->addModel($model);   //fails
