Apologies if this has already been answered, However I was trying to implement a module, however had the “[Links to :: ]” syntax in a query. I’m not familiar with this, nor do I recognise this from SMW. I’ve done quite a bit of googling however I have yet to stumble upon an extension that implements this.
I searched around in the ExtraSpecialProperties extension, however couldn’t find it, I also found this question using it, however no context was given: Semantic MediaWiki Get page links?
You will need the extension Semantic Scribunto.
Having installed that, you can call mw.smw.getQueryResult() or mw.smw.ask().
Both functions, especially the latter, return rather complex Lua tables; you could use mw.dumpObject() or mw.logObject() to study the structure of the returned tables in the console below the module edit window, in order to find out how to extract only the data you need.
