That sounds very good. I just realized that you asked before about the Google Summer of Code - there's a student who's applying to the GSoC to work on adding full support for mapping services to SMW - most notably updating Semantic Layers, but also, if there's time, adding support for services like Google Earth and Yahoo Maps. I'm signed up to be his mentor. I was planning to write more about it once we knew whether his application was accepted or not.

I didn't see any complaints about this functionality so I'll go ahead and check it into the repository.


Thank you,

As promised, I added "Show embed code" link to Special:Ask page:
http://www.techpresentations.org/Special:Ask?title=Special%3AAsk&q=[[Category%3ARFC]]&po=%3FRFC+date%0D%0A%3FRFC+title%0D%0A%3FRFC+author%0D%0A%3FRFC+document+URL%0D%0A&eq=yes&p=format%3Dbroadtable&eq=yes

When clicked, it shows the code for {{#ask:...}} parser function that you can use to embed current results (including format) into a page anywhere on your wiki.

I think that together with format selector, it'll help people create more data-driven wikis. So if nobody objects, I'll check it in for all to enjoy. Patch can be seen here: http://www.techpresentations.org/SMW_Ask_embed.patch / http://www.techpresentations.org/SMW_Ask_embed.patch.html (colorized)

Also, during development, I noticed a few bugs or missing features of Special:Ask page:
  • Not all formatters work on Special:Ask, for example googlemap, debug, count and calendar don't work or display something different from what I'd expect them to do
  • count and order parameters always get set in the code so even when they are not defined, in the embed code they appear with empty values. I decided not to filter out parameters with empty values as some parameters might actually be meaningful. It's possible that count and order are just not initialized properly when $wgRequest->getVal( 'order' ) and $wgRequest->getText( 'sort' ) are used unconditionally
  • there is no way to display any meaningful title for a formatter or know whenever to include one in the list or not (debug) - current formatter classes are limited in this sense
  • there is no way to configure formatter on Special:Ask page except for just asking user for a list of additional attributes similar how printouts are asked for. This is limiting the use of formatting feature and renders some formatters completely useless (template, for example). I think it's worth looking into expanding SMWResultPrinter to carry more metadata and maybe form definition for accepted parameters.
I hope to have time in the future to address some of these, but don't know when I'll have more time for it.

Markus, Denny, let me know if it's a good idea to add these into Bugzilla to keep track of them.

BTW, is SMW participating in GSoC?

Thank you,
