SMW is such a powerful tool, but it's designed like its target audience is mind readers who can divine what it needs to function. It either installs without issue or fails so cryptically that support is impossible. In pursuit of being a generic tool, the end-user docs and help are still so allergic to examples for its esoteric query syntax or use cases for property design that SMW effectively doesn't even exist for non-admins. Its extension-specific database changes are still their own hassle to upgrade separate from MW's. And the closest thing to an active support community is a Sourceforge email list.

Cargo's still easier to work with and its query syntax is a lot more SQL-like, even with the reduced feature set.

I would recommend Cargo instead of SMW, Cargo lets you use an RDB more directly, and you can do much more powerful things as a result. Cargo has been a better option than SMW since about 2018 or so imo

The SMW developer community seems to be less active now a days, so i suspect SMW is even worse now.
