Sorry about that--I'm in Tokyo this week for business and have been busy
with things. I'm the one who did the most work to set up the current
templates, so I think other folks weren't chiming in because they don't
know the area as well.

I've responded inline, but in general I think your ideas are spot on. *Do
you want to file bugs on the bugzilla to track these?* That will make sure
we don't forget these awesome ideas. Feel free to set me as the owner. In
practice, we may want to split up the work on these if you're able to help.

I think this is a good idea, and it should be *relatively *easy to
accomplish by having an additional nested template type.

I reached out to the creator of Semantic Forms about this. I agree that the
preview mode bug is confusing (at best).

As for auto escaping of code, I'm not sure how we could best accomplish
that directly in media wiki/semantic forms.

There's an ability to mark any reference article (including
Methods/Properties) as being standard/obsolete/non-standard, etc.  Making
it so that those would be pulled out in the summary tables on API Objects
should be relatively easy. Another good thing t o

This could get very expensive to do, because the code on each API Object
page would have to run a separate query for each level up the chain, even
if those levels don't exist.

The work around that's currently implemented (and I think is better) is
that each API_Object page accepts a comma-delimited list of pages in the
Subclass_of field. If you provide more than one, it will print them all out
on the page (although not collated together). This is not very clear in the
current documentation of the templates.

Agreed.

http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Semantic_Forms_and_templatesis
where ArrayMap is documented. You can see it in action in
http://docs.webplatform.org/wiki/Template:API_Object , among other pages.

Hmmm. The main documentation for semantic forms is:
http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms .
Based on that, I think the answer is no. The reason is that even if we were
to use "values from category", the page titles would all be too long. What
we'd want is the *last bit of the title *for every page in the group.

Hmm, that must have been an error in the import. For now the best way to
fix this (and this is not an ideal answer, I know) is to manually remove
the erroneous values in the Subclass_of form field for each of those
articles. :-/

Unfortunately, I don't believe it's possible to include javascript in the
semantic forms. If there are a number of places where this would be useful
(I think we've enumerated a few just in this e-mail), it might be useful to
ask the creator of Semantic Forms if it's possible to do that.

I just investigated a bit more and it's not obvious to me how to do the
appropriate conversion in MediaWiki markup/parserfunctions.
