[Rdfapi-php-interest] Problem with InfModelF

[Peter B. <pb...@xs...>]

Hi,

The InfModelF does, among other things, type inference.
If 	a rel b
and 	rel range c
it infers:
	b type c.

This is nice. However, when I have a literal property
	a rel 'abc'
and 	rel range http://www.w3.org/2001/XMLSchema#string
it will infer:
	'abc' type http://www.w3.org/2001/XMLSchema#string
which obviously won't work.

The error is given as:
Fatal error: RDFAPI error (class: Statement; method: new): Resource 
expected as subject. in 
d:\Inetpub\wwwroot\emblems\lab\rdfapi091\rdfapi-php\api\model\Statement.php 
on line 66

I may of course be doing something wrong. Could someone help shed light 
on this?

Thanks in advance,
Peter Boot

My very simple PHP script:
<?php
define("RDFAPI_INCLUDE_DIR", 
"d:/inetpub/wwwroot/emblems/lab/rdfapi091/rdfapi-php/api/");
include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");
$im = ModelFactory::getInfModelF();
$im->load("http://emblems.let.uu.nl/emblems/lab/dse/rdf/test.rdf");
?>
