It does look pretty abandoned. The extension’s listed author MWJames last edited in 2015. Extension is not deployed to Wikimedia production and is not listed at https://www.mediawiki.org/wiki/Developers/Maintainers. Last human commit is Nov 2022: https://github.com/SemanticMediaWiki/SemanticCite/commits/master.

The listed maintainer is “SMW Project”, with a link to https://www.semantic-mediawiki.org/wiki/Help:SMW_Project. Asking the SMW Project folks might be worth a try. Could also try emailing or posting on the user talk of MWJames.

Sincerely,

Hello folks!

does anybody know if this extension is still maintained? The latest commit is from May 16, 2020.

There are older tickets about SCI being not compatible with SWM 4.0.0 (and therefore not compatible with MW1.39 which will become EOL end of 2023).
