Hey,
So you'd have something like
{{#gimmeh_datas_in_a_table: [[Category:Some category]]}}
that results in the same output as the #ask call you posted? If that's all
you're doing you can of course just use a template. Which indeed does not
work if you want to modify the result in certain ways.
Hey,
Hopefully writing result formats will become even easier
and more pleasant task!
Hopefully it will yes! Though this will not be brought with using the Ask
library, as the technical issues faced there are mostly disjoint from the
Ask language. That being said, having a nicer implementation

I'm happy to announce the initial release of the Ask library!
A small write-up of this release can be found at

There is no discussion about this, as quite some work needs to happen

I was using SMW 1.5 ( with MW 1.15.6) and added my own special property

I changed it back to SQLStore2 in LocalSettings.php and i do see some
results.
Special:Properties list 199 properties when SQLStore2 is used where as only
73 when SQLStore3 is used.
I did not see any error while migrating, but will give it a 2nd try.

I get a list of the pages in category Maps when I use the query:

Just to make sure, did you refresh your data after moving to SqlStore3? You
need to do that before any data will show up.

I don't think doing the implementation would really be that hard.
There would need to be a refreshMetaSemantics.php maintenance

maybe some other tasks like viewing. It should probably only keep
