            Bug ID: 46458
           Summary: Ability to use count via the SMW Ask API
           Product: MediaWiki extensions
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: Unprioritized
         Component: Semantic MediaWiki
          Assignee: [email protected]
          Reporter: [email protected]

I would love to add some deeper semantic statistics to WikiApiary beyond what
is reported in the smwinfo API method. This enhancement request could be seen
as a request to add more to smwinfo, but I think it would be better (and more
generic) as an enhancement to the Ask API.

I would specifically like to execute this query via the API:

{{#ask:[[Query size::+]]|format=count}}

by doing:

http://wikiapiary.com/w/api.php?action=ask&query=%5B%5BQuery%20size%3A%3A%2B%5D%5D%7Cformat%3Dcount&format=json

Right now this will result in a PHP exception:

PHP message: PHP Catchable fatal error:  Argument 1 passed to
ApiSMWQuery::addQueryResult() must be an instance of SMWQueryResult, string
given, called in **/SemanticMediaWiki/includes/api/ApiAsk.php on line 48 and
defined in **/SemanticMediaWiki/includes/api/ApiSMWQuery.php on line 82

The Ask API does allow parameters like sort and order to be passed, but it
doesn't seem to handle format at all. For most cases format doesn't make sense
(table, ul, array). However, aggregation formats methods like count, max, min,
earliest, latest do make a lot of sense.

It would be really great to be able to do these queries via the API. I would
then add this as extended semantic information to retrieve and graph in
WikiAiary. :-)
