Topic on Extension talk:PageProperties

Hi, my platform is 1.36. After I installed the extension, all pages in my wiki occured error as below:

EasyRdf\Parser\Exception: XML error: "XML_WAR_NS_URI" on line 44, column 4

Backtrace:

How can I fix it? Thanks!@Thomas-topway-it

@JayLiu7319 I'm not sure, can you try to install semsol/arc2 and using the following

				$parser = ARC2::getRDFParser( );
				$parser->parse(  $rdf_export );
 				$serialiser = ARC2::getSer('JSONLD');

 				$triples = $parser->getTriples();
				$index = $parser->getSimpleIndex( $triples, false );
				//$index = $parser->getSimpleIndex( 0 );

         		$output = $serialiser->getSerializedIndex($index);

in the function includes/PageProperties.php => BeforePageDisplay

instead than

				$foaf = new \EasyRdf\Graph( $rdf_export );
				$foaf->load();

				$format = \EasyRdf\Format::getFormat( 'jsonld' );
			
				$output = $foaf->serialise( $format, [
					'compact' => true,
				] );

Thank you very much! @Thomas-topway-it It works!

@JayLiu7319

so EasyRDF is not working and ARC2 does ?

I think we should investigate more about that ...
