The Semantic Dependency Updater (SDU) extension monitors pages for changes in their semantic data. If the "Semantic Dependency" property is found, this extension will update all pages that have been selected through that property. A common use case is change propagation where pages need to update (pull) their semantic data via an ask query from a changed page.
The "Semantic Dependency property" is evaluated as an ASK query. It is therefore possible to define either a list of pages directly or do more complex selections.
Installation

Instead of downloading the zip archive you may also check this extension out via Git:
git clone https://github.com/gesinn-it/SemanticDependencyUpdater.git extensions/SemanticDependencyUpdater
Configuration
Mandatory
Make sure, a "Semantic Dependency" property exists, e.g. "Property:Semantic_Dependency" needs to exist and MUST be of the datatype Text
:
[[Has type::Text]]
Optional
// Name of the Semantic Dependency property
$wgSDUProperty = 'Semantic Dependency';
// If enabled, SDU will create a Job for each update
$wgSDUUseJobQueue = false;
Usage
The value of the Semantic Dependency property is evaluated as an ASK query, except that [[
or ]]
must be ommitted.
If there are more conditions, combine them through AND
and OR
Examples
Update Self
This will save the current page twice. Useful when the page stores semantic properties that are calculated from other properties of the same page.
[[Semantic Dependency::{{FULLPAGENAME}}]]
Update other page(s)
[[Semantic Dependency::Product:Test Product]] [[Semantic Dependency::{{{Target Page|}}}]]
Update pages with relation to current page
This will update all pages that link with Part Of
to the current page.
[[Semantic Dependency::Part Of::{{FULLPAGENAME}}]]
More Advanced Queries
Be careful that the query does not return too many pages, as this will result in a heavy load.
[[Semantic Dependency::Category:Product]] [[Semantic Dependency::Category:Product AND Tag::Demo]] [[Semantic Dependency::Category:Person OR Category:Organization]]
Example test case
- Make sure, a page
Property:Semantic_Dependency
exists with content[[Has type::Text]]
- Make sure,
$wgSDUUseJobQueue = false;
- Create a page
A
with
[[Title::A]]
- Create a page
B
with
* [[Part Of::A| ]][[Title::{{#show:A|?Title}}.B]] * {{#show:{{FULLPAGENAME}}|?Title}}
- Now, change page
A
as follows
[[Title::XXX]]
As a result, you should see
- XXX.B - XXX.B
on page B
Debugging
- Note, that on some systems logging to /tmp might not work
- Make sure, a log folder, writable by your web server, exists
> mkdir /var/log/mediawiki > chown -R www-data /var/log/mediawiki
- In your LocalSettings enable
$wgDebugLogGroups['SemanticDependencyUpdater'] = '/var/log/mediawiki/SDU.log';
- Watch the log file
> tail -f /var/log/mediawiki/SDU.log
- If things work as expected, this will look like:
