I think a maintenance script is a good idea. Perhaps even a button on a
SMW "special page" to trigger the script for easy use when you need it
right away.
I'm wondering if the effort to generally improve the way templates work
with SMW might go hand in hand with the effort to formally support SMW in
templates with Mediawiki (Without having to patch parser.php)
While I'm rambling on to this other topic it would be wonderful to not have
to apply a patch to Mediawiki down the road. I'm trying to formally move
our wiki into more of a "production" state, and telling our Unix/system
admins that they need to apply a patch to parser.php every time they do a
quarterly software update on Mediawiki probably won't sit to well with
them. As it is now I play that role and do the patching, but it's not
really my job. I just happen to be the techy wiki evangelist at the
moment...
One more thing. You guys probably don't hear this enough: Thanks! to all
the SMW developers, you guys are doing an awesome job.

AM child content for "ask" queries
Hi,
Inline queries work by doing database queries on the tables that store
the attributes and relations that have been defined. Whenever you save
(or re-save) a page that defines attributes and relations, the old
attributes and relations (if there were any) get removed from the
database, and the new ones are added. After that, the new data should
show up in inline queries immediately; though you might need to do a
refresh on the page *that holds the query*, to prevent caching.
I'm guessing that the problems you're all experiencing are brought on
by the use of templates. If pages define attributes and relations
indirectly through templates, and you change some of the semantic
structure of a template, that change won't be reflected in the
database: you'll need to re-save each of the pages that use that
template. If you change around the categories in a template, that
change will show up in the database, without any work on your part;
though it takes a few minutes. But that need to re-save is certainly
annoying, especially since there can often be a lot of trial-and-error
in deciding how templates should be structured.
I think what's needed (and it's been discussed before a few times) is
a maintenance script that wipes out all the semantic data in the
database and recreates it. It seems like a lot of people would benefit
from such a tool.
