I have been playing with ideas from this thread to do the same thing - add
predefined properties from an extension.
I came down to this basic code to add user defined properties (based on a
predefined string $propertyName and a calculated value from my extension
$value)
$property = SMWPropertyValue::makeUserProperty( $propertyName );
$dv = SMWDataValueFactory::newPropertyObjectValue( $property, $value
);
SMWParseData::getSMWData( $parser )->addPropertyObjectValue(
$property, $dv );
I am also using the 'ParserAfterTidy' hook since it seems more appropriate
to my extension is doing (add semantic annotations for authors of a page).
At this point, my problem is this :
1- If I use this code as-is, no value seems to be saved for this page
2- If I use SMWParseData::storeData as indicated above, I lose some
properties since storeData assumes parsing has been done when it is called.
3- If I use a direct access to the store by replacing :
SMWParseData::getSMWData( $parser ) by :
smwfGetStore()->getSemanticData($wgTitle) , values are saved but they get
wiped out at the next refresh job.
My question (and I assume, the original question as well) :
How do I go from this user property code to saved values that will persist
after a refresh ?
Based on Markus recommendation, I did check the custom properties added by
SME_ParseData and it seems that nothing more is needed than what I have
above.
Any insight ? code sample ? nudge in any direction ? :)
