Not a lot of information here about how this can be used on a non-Wikimedia project, even though references to this page seem to imply that it can be used on such a project (See the notice on Extension:TextExtracts). I'm trying to figure out how to automatically create description meta tags on my wiki for when pages are linked, and this site always seems to point me back here, but with no information on how to proceed.
Talk:Page Content Service
Non-Wikimedia meta descriptions
The PCS doesn't provide the meta tags on https://en.wikipedia.org/wiki/Foobar, it provides https://en.wikipedia.org/api/rest_v1/page/mobile-html/Foobar and https://en.wikipedia.org/api/rest_v1/page/summary/Foobar and similar. To a first approximation, none of the code is re-usable outside of Wikimedia, though it could probably be generalised at a cost of performance.
Ok, so then this doesn't provide the description meta tags, correct? And even if it did, the Page Content Service isn't usable outside Wikimedia anyways, right? Perhaps that should be clarified then. Thanks anyways!
Needs non-Wikimedia context
There's very little context here for MediaWiki users coming from 1.27 LTS. The linked Page Content Service Project Google Doc at https://docs.google.com/document/d/15EAaDwK70i2pT4Xkj2Kdp9Q8XsYKGUQkJTSj5Rq8xiE/edit is not public. There's no information on this page about whether this is built into MediaWiki, an extension, or an external service, and if an extension or external service where to find it or how to install or configure it.
It's a service designed and built for Wikimedia. How did you come to read it, and what problem were you hoping it might solve? Maybe there's an alternative to which I could point you.
